This feat is really bad and uninteresting. Most times you burst something, the damage bonus is lost anyways as that enemy is dead.
If the feat also increased Brain bursts damage by 25%, or enough that it would 1 hit flamers in T5 and 2 tap crushers in the right scenerio it would actually be worth considering and most importantly fun!
You can already do that.
Without cerebral lacerations.
1st feat lvl 10 + 1st feat lvl 25
With enough warp charges+peril, you can 1 shot flamer, poxburster, dreg rager, scab rager.
With 6 warp charges and when both BB casts are started when around 60%+ peril, you can 2 shot a crusher.
Outside of bossfights and you trying to 2 shot a crusher more easily, cerebral lacerations is really not worth much.
I am aware you can do that. Lacerations making it so you don’t need to combo up to make that possible would be a good change.
What you say above is true. That doesn’t make the feat as it is less pointless. Lacerations right now is objectively bad, and a damage bonus would make it more interesting.
Alternatively, increasing the bonus from 25% to 50% or more would make it fun .
Right now, no one takes it, and I think there should be a build that puts brain burst front row and center that is viable and lacerations could be a lynchpin feat for that
