Check our group msg, me & uzura quite seasoned already. I've reached Dark Invoker level (last boss aka level  15) & with Uzura, we reached Alche level (2nd last level). Lai lai join, anything for 1 less pinoy.

only reach alchemist stage on darkmoon.
rly hard to fight this 6 alchemist.
set..underlord,ds,medusa,treant and techies..

Ok, so we're stuck consistently at Injoker. Any ideas how to handle him? We have hex, bloodthorn, BKB....ain't helping much.

Let's start with critically needed heroes

Treant & Pit Lord definitely good to have as tank, especially Pit Lord's aura. Dark Seer's wall is a savior when there's a mass of his minions. Is hiding for few seconds in Tusk's snowball even helpful? Is Medusa's disable helpful?

What I felt dysfunctional against Invoker

PA doesn't seem like a legit tank since she's relying on evasion to tank, unless she can evade Invoker's magical nukes & PA keeps on getting disarmed anyway to even hit Invoker.  Sniper is somewhat redundant vs invoker, whenever wanna Assassinate will surely kena sunstrike to death, so can only shoot non-stop from a distance.  Whoever trapped in Winter Wyvern's ice cube will be sunstriked to death.

Ideal Battlefield?

We usually engage Invoker in just front of base, at the T2 top tower. Is it recommended to engage him at the further tower from base? Any strategic location to trap him or hero position/formation?

Itemization

We Solar Crest, Hex & Silence continuously but he seems to be able to cast some spells while disabled. Any way to survive his spells, especially Meteor & Tornado besides BKB? BKB ain't that reliable cause of long cooldown & BKB doesn't protect from Sunstrike. Raindrop? Pipe? Are those even relevant when he's nuking like 1k damage? Any other recommended items?
