Kill Burtok Challenge

A poorly designed challenge indeed - as it heavily limits you when you did not build for physical melee or bows.


Besides puncture, one other option is:

Vaal Double Strike + Chance to Bleed + increased duration.
It has no specific weapon limitation.

When you have Vaal charged, you can hit once to summon two copies for 10s (more if your build has duration in passive tree).
At 50% bleed chance.

I would assume they can keep up the bleed for a while. Damage does not matter as you just need to make sure you can actually hit.
Vaal version has 100% hit chance.
