Last skill rune on vault. When used, it creates a trail of fire.

1hand crossbow have the least dmg but high att speed and you could equip shield with it or dual wield.

2h xbow on the other hand have the highest dmg but the slowest att speed.

Most SC will equip a 2h xbow as it provides the highest dmg output and most HC will equip a 1h xbow to equip a shield.

The easiest way is to stack high def (~4k if possible but 3k is alreayd doable for butcher), high vit (at least 30k), and high dex for dmg. I completed A1 inferno in HC with practically less than 100AR. Playing a glass cannon 1 shot death is gonna take plenty of death till you are able to time butcher moves to perfection and also with bit of luck. So, best way is to build better survivabiltiy. Instead of using your gold for repair, use it to buy gear and don't die saving repair cost. Key is not to die often and you will be able to save gold.

As for me, hopefully will be able to complete A2 inferno HC soon, now progressing slowly, so far so good, of course in A2, you will need better survivability stats than what I've mentioned.

Equips are generally pretty cheap now. You don't need to stack high AR to complete butcher. Good luck.

Defense as in armor. Get a piece that has high armor + main stat + vit on it. Not every piece needs to actually be very high armor to achieve ~4k defense. It's extremely doable.

Added on August 28, 2012, 12:10 pmIf you switch skills, you can kill butcher even faster. With your build, I think can faceroll whole of inferno already, of course you will need experience first to handle mobs in inferno as DH first before facerolling. You don't need to stack so much att speed IMO. Getting about 2x% is good enough for me. Better to concentrate on crit rate and crit dmg. Having discpline based equips is a great plus too though might not be necessary for you since your survivability stats is very good.
