New Death Knight Abilities

Outbreak (level 81): Outbreak infects the target with both Frost Fever and Blood Plague at no rune cost. This ability allows death knights to apply diseases quickly when they are switching targets or when their diseases have been dispelled.

Necrotic Strike (level 83): Necrotic Strike is a new attack that deals weapon damage and applies a debuff that absorbs an amount of healing based on the damage done. For context, imagine that the death knight can choose between doing 8,000 damage outright with a certain ability, or dealing 6,000 damage and absorbing 4,000 points in incoming heals with Necrotic Strike -- the burst is smaller, but a larger overall amount of healing would be required to bring the target back to full health.

This ability is meant to bring back some of the old flavor from when death knights could dispel heal-over-time (HoT) effects. It also gives the class a bit more PvP utility without simply replicating a Mortal Strike-style effect.

Dark Simulacrum (level 85): The death knight strikes a target, applying a debuff that allows the death knight to copy the opponent's next spell cast and unleash it. Unlike Spell Reflection, Dark Simulacrum does not cancel the incoming spell. In general, if you can't reflect an ability, you won't be able to copy it either.

Rune System Changes

While we're satisfied with the way the rune system works overall, we're making a few major changes to the mechanics that will ultimately help death knight players feel less constrained. Here's the rationale behind the changes, followed by an explanation of how the new system will work.

In the current rune system, any time a rune is sitting idle, death knights are losing out on potential damage output. By comparison, rogues spend most of their time at low energy levels, and if they're unable to use their skills for a few seconds, that energy builds up and can be spent later, minimizing the net loss from the interruption.

A death knight's runes, on the other hand, cannot be used until they are fully active. If a death knight ever goes more than a few seconds without spending an available rune, that resource is essentially wasted. Because the death knight is pushing buttons constantly, it can be difficult to add new mechanics to the class because the player doesn't have any free global cooldowns to use them. We can't grant extra resources or reduced cost, because there is no time to spend them. Missing an attack is devastating, and it's impossible to save resources for when they're most useful.

Additionally, each individual death knight ability has a fairly low impact on its own, making it feel like most of the death knight's attacks are weak. The death knight's rotations are also more easily affected by latency or a player's timing being just a little off. At times, it feels like death knights aren't able to take advantage of their unique resource mechanic, which can diminish the fun.

The new rune system will change how runes regenerate, from filling simultaneously to filling sequentially. For example, if you use two Blood runes, then the first rune will fill up before the second one starts to fill up. Essentially, you have three sets of runes filling every 10 seconds instead of six individual runes filling every 10 seconds. (Haste will cause runes to fill faster.) Another way to think of this is having three runes that go up to 200% each (allowing extra "storage"), rather than six runes that go up to 100% each.

As this is a major change to the death knight's mechanics, it will of course require us to retune many of the class's current abilities. For example, each ability needs to hit harder or otherwise be more meaningful since the death knight is getting fewer resources per unit of time. Some abilities will need to have their costs reduced as a result.

Talent Changes

Next we'll outline some of the death knight talent-tree changes we're planning in Cataclysm. This list is by no means comprehensive, but it should give you a sense of how we're intending each death knight spec to perform.

One of the biggest changes we're making is converting Blood into a dedicated tanking tree. While we feel that having three tanking trees was successful overall, it's less necessary in a world with dual-specialization. In addition, the current breakdown isn't as compatible with the Mastery-based passive talent-tree bonuses we want to add (see below). We'd rather spend time tweaking and balancing one good tanking tree rather than having a tank always wondering if they picked the "correct" tree out of three possibilities.

Blood seemed like the best fit for tanking. Unholy has always had a strong niche with diseases, magic, and command over pets. Frost now feels like a solid dual-wield tree with Frost magic damage and decent crowd control. Blood's niche was self-healing -- fitting for a tank -- as well as strong weapon swings, which could easily be migrated to Frost and Unholy.

Our plan is to move the most interesting and fun tanking talents and abilities to Blood. For example, you will likely see Vampiric Blood and Will of the Necropolis remain, while Bone Shield will move over from Unholy.

Mastery Passive Talent Tree Bonuses

Blood
Damage reduction
Vengeance
Healing Absorption

Frost
Melee damage
Melee Haste
Runic Power Generation

Unholy
Melee damage
Melee and spell critical damage
Disease Damage

Healing Absorption: When you heal yourself, you'll receive an additional effect that absorbs incoming damage.

Runic Power Generation: This will function as the name implies, and the new rune system will make generating Runic Power more appealing.

Disease Damage: Unholy death knights will be able to get more out of their diseases, which are integral to the tree's play style.

Vengeance: This new mechanic is designed to ensure that tank damage output (and therefore threat) doesn't fall behind as damage-dealing classes improve their gear during the course of the expansion. All tanking specs will have Vengeance as their second talent tree passive bonus. Whenever a tank gets hit, Vengeance will grant a stacking Attack Power buff equal to 5% of the damage done, up to a maximum of 10% of the character's unbuffed health. For boss encounters, we expect that tanks will always have an Attack Power bonus equal to 10% of their health. The 5% and 10% bonuses assume 51 talent points have been put into the Blood tree; these values will be smaller at lower levels.

You only get the Vengeance bonus if you have spent the most talent points in the Blood tree, so you won't see Frost or Unholy death knights running around with it. Vengeance will let us continue to design tank gear more or less the way we do today; there will be some damage-dealing stats, but mostly survival-oriented stats. Druids typically have more damage-dealing stats even on their tanking gear, so their Vengeance benefit may be smaller, but the goal is that all four tanks will do about the same damage when tanking.

We hope you enjoyed this preview, and we're looking forward to hearing your thoughts and feedback on these additions and changes. Please keep in mind that this information represents a work in progress and is subject to change as development on Cataclysm continues.

New Druid Abilities

Thrash (Level 81): Thrash deals damage and causes all targets within 10 yards to bleed every 2 seconds for 6 seconds. The intent here is to give bears another button to hit while tanking. Talents will affect the bleed, such as causing Swipe to deal more damage to bleeding targets. 5-second cooldown. 25 Rage.

Stampeding Roar (Level 83): The druid roars, increasing the movement of all allies within 10 yards by 40% for 8 seconds. Stampeding Roar can be used in cat or bear form, but bears might have a talent to drop the cooldown. The goal of this ability is to give both bears and cats a little more situational group utility. 3-minute cooldown. No cost.

Wild Mushroom (Level 85): Grows a magical mushroom at the target location. After 4 seconds the mushroom becomes invisible. Enemies who cross the mushroom detonate it, causing it to deal area-of-effect damage, though its damage component will remain very effective against single targets. The druid can also choose to detonate the mushroom ahead of time. This is primarily a tool for the Balance druid, and there will be talents that play off of it. No cooldown. 40-yard range. Instant cast.


Changes to Abilities and Mechanics

In addition to the new abilities listed above, we intend to make changes to some of the other abilities and mechanics with which you’re already familiar. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of our goals for each spec.

All heal-over-time spells (HoTs) will benefit from crit and haste innately in Cataclysm. Hasted HoTs do not reduce their duration, but instead add additional HoT ticks. Haste will also benefit Energy generation while in cat form.
Unlike the other healers, Restoration druids will not be receiving any new spells. They have plenty to work with already, and our challenge instead is to make sure all of them have a well-defined niche. A druid should be able to tank-heal with stacks of Lifebloom, spot-heal a group with Nourish and Regrowth, and top off lightly wounded targets with Rejuvenation.
We want to add tools to cat form and depth to bear form. If a Feral cat is going to fill a very similar niche to that of a rogue, warrior or Enhancement shaman, it needs a few more tools -- primarily a reliable interrupt. Bears need to be pushing a few more buttons just so the contrast between tanking and damage-dealing is not so steep.
Barkskin will be innately undispellable.
We will be buffing the damage of Mangle (cat) significantly so that when cat druids cannot Shred, they are not at such a damage-dealing loss.
Druids will lose Abolish Poison with the dispel mechanics change, but Restoration druids will gain Dispel Magic (on friendly targets) as a talent. All druids can still remove poisons with Cure Poison and remove curses with Remove Curse.


New Talents and Talent Changes

Tree of Life is changing from a passive talent to a cooldown-based talent, similar to Metamorphosis. Mechanically, it feels unfair for a druid to have to give up so much offense and utility in order to be just as good at healing as the other classes who are not asked to make that trade. We are exploring the exact benefit the druid gets from Tree of Life. It could strictly be better healing, or it could be that each heal behaves slightly different. You also will not be able to be banished in Tree of Life form (this will probably be true of Metamorphosis as well). Additionally, we would like to update the Tree of Life model so that it feels more exciting when you do decide to go into that form. Our feeling is that druids rarely actually get to show off their armor, so it would be nice to have at least one spec that looked like a night elf or tauren (and soon troll or worgen) for most of the time.
We want to make the Feral cat damage rotation slightly more forgiving. We do not want to remove what druids like about their gameplay, but we do want to make it less punishing to miss, say, a Savage Roar or Rake. The changes here will be on par with increasing the duration of Mangle like we did for patch 3.3.3.
Balance druids will have a new talent ability called Nature’s Torrent, which strikes for either Nature or Arcane damage depending on which will do the most damage (or possibly both), and moves the Eclipse meter more (details below). The improved version of Nature’s Torrent also reduces the target's movement speed. 10-second cooldown.
Restoration druids will have a new talent called Efflorescence, which causes a bed of healing flora to sprout beneath targets that are critically healed by Regrowth.
We plan on giving Feral cats and bears a Kick/Pummel equivalent -- an interrupt that is off the global cooldown and does no damage. We feel like they need this utility to be able to fill the melee role in a dungeon or raid group, and to give them more PvP utility.
We want to make sure Feral and Balance druids feel like good options for an Arena team. They need the tools to where you might consider a Feral druid over an Arms warrior, or a Balance druid over a mage or warlock. Remember that the PvP landscape will probably look pretty different for Cataclysm with a focus on rated, competitive Battlegrounds.


Mastery Passive Talent Tree Bonuses

Balance
Spell Damage
Spell Haste
Eclipse

Eclipse: We are moving Eclipse from a talent into a core mechanic of the class and making it less random. Balance druids will have a new UI element that shows a sun and a moon. Whenever they cast an Arcane spell, it will move the UI closer to the sun, and buff their Nature damage. Whenever they cast a Nature spell, it will move the UI closer to the moon, and buff their Arcane damage. The gameplay intention is to alternate Arcane and Nature spells (largely Starfire and Wrath) to maintain the balance.

Feral (Cat)
Melee Damage
Melee Critical Damage
Bleed Damage

Feral (Bear)
Damage Reduction
Vengeance
Savage Defense

Bleed Damage and Savage Defense: Feral druids will receive two sets of passive bonuses depending on whether the druid is in cat or bear form. Bleed Damage will be improved for cats. Savage Defense is the current bear mechanic for converting crits into damage absorption and will be improved for bears.

Vengeance: This is a mechanic to ensure that tank damage (and therefore threat) doesn’t fall behind as damage-dealing classes improve their gear during the course of the expansion. All tanking specs will have Vengeance as their second talent tree passive bonus. Whenever a tank gets hit, Vengeance will give them a stacking attack power buff equal to 5% of the damage done, up to a maximum of 10% of the character’s unbuffed health. For boss encounters we expect that tanks will always have the attack power bonus equal to 10% of their health. The 5% and 10% bonuses assume 51 talent points have been put into the Feral tree and the druid is in bear form -- these values will be smaller at lower levels. Remember, you only get this bonus if you have spent the most talent points in the Feral tree and are in bear form, so you won’t see Balance, Restoration, or Feral druids in cat form running around with it. Vengeance will let us continue to make tank gear more or less the way we do today -- there will be some damage-dealing stats, but mostly survival-oriented stats. Druids typically have more damage-dealing stats even on their tanking gear, so the Vengeance benefit may be smaller, but overall the goal is that all four tanks do about the same damage when tanking.

Restoration
Healing
Meditation
HoT Scale Healing

HoT Scale Healing: HoTs will do increased healing on more wounded targets. The mechanic is similar to that of the Restoration shaman, but with HoTs instead of direct heals. In Cataclysm, we anticipate druids using a greater variety of their spells so there is a distinction between healing and HoT healing.

New Mage Spells

Flame Orb (available at level 81): Inspired by Prince Taldaram’s abilities in Ahn'kahet and Icecrown Citadel, this spell allows the mage to cast a flaming orb that travels in front in a straight line, sending beams that cause fire damage to passing targets. Once it’s cast, the mage is free to begin casting other spells as the Flame Orb travels. While the spell will be useful to any spec, Fire mages will have talents that improve it, possibly causing the Flame Orb to explode when it reaches its destination.

Time Warp (level 83): Grants a passive Haste effect much like Bloodlust or Heroism to party or raid members. It also temporarily increases the mage's own movement speed. Time Warp will be exclusive with Bloodlust and Heroism, meaning you can’t benefit from both if you’ve got the Exhaustion debuff, though the movement-speed increase will still work even when under the effects of Exhaustion.

Wall of Fog (level 85): Creates a line of frost in front of the mage, 30 yards from end to end. Enemies who cross the line are snared and take damage. The mana cost will be designed to make Wall of Fog efficient against groups, not individuals. This spell is intended to give mages a way to help control the battlefield, whether the mage is damaging incoming enemies (Blizzard can be channeled on top of Wall of Fog) or protecting a flag in a Battleground. 10-second duration. 30-second cooldown.

Changes to Abilities and Mechanics

In addition to introducing new spells, we're planning to make changes to some of the other abilities and mechanics you're familiar with. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of what we intend for each spec.

Arcane Missiles is being redesigned to become a proc-based spell. Whenever the mage does damage with any spell, there is a chance for Arcane Missiles to become available, similar to how the warrior’s Overpower works. The damage and mana cost of this spell will be reworked to make it very desirable to use when available. This change should make gameplay more dynamic for the mage, particularly at low levels.
We are planning to remove spells that don't have a clear purpose. Amplify Magic, Dampen Magic, Fire Ward, and Frost Ward are being removed from the game, and we may remove more.
The ability to conjure food and water will not become available until higher levels (likely around level 40), as we're making changes to ensure mages generally won’t run out of mana at lower levels. Once mages learn how to conjure food and water, the conjured item will restore both health and mana.
Scorch will provide a damage bonus to the mage's fire spells. Our goal is for Scorch to be part of the mage's rotation and a useful damage-dealing ability, even if someone else is supplying the group with the spell Critical Strike debuff. Scorch will provide the mage with more specific benefits, which can also be improved through talents.


New Talents and Talent Changes

Arcane Focus will now return mana for each spell that fails to hit your target, including Arcane Missiles that fail to launch. We want Arcane mages to have several talents that play off of how much mana the character has and give the player enough tools to manage mana.
The talent Playing with Fire will reduce the cooldown of Blast Wave when hit by a melee attack, instead of its current effect.
Pyromaniac will grant Haste when three or more targets are getting damaged by the effects of your damage-over-time (DoT) fire spells.
The Burnout talent will allow mages to cast spells using health when they run out of mana.


Mastery Passive Talent Tree Bonuses

Arcane
Spell damage
Spell Haste
Mana Adept

Mana Adept: Arcane will deal damage based how much mana the mage has. For example, Arcane mages will do much more damage at 100% mana than at 50% mana. If they begin to get low on mana, they will likely want to use an ability or mechanic to bring their mana up to increase their damage.

Fire
Spell damage
Spell Crit
Ignite

Ignite: All direct-damage fire spells will add a damage-over-time (DoT) component when cast. The flavor will be similar to how Fireball works; however, the DoT component will be much stronger.

Frost
Spell damage
Spell Crit damage
Deathfrost

Deathfrost: Casting Frostbolt places a buff on the mage that increases the damage for all frost, fire, and arcane spells. The only damage spell that won't be affected by this buff is Frostbolt.
