The thing that bothers me about things like overwhelm, is these are 100% guaranteed to hit no matter what.
Why can a lowly spider that can't even hit me, overwhelm be automatically and chew off my face.
Then beyond that, unlike most other attacks with effects, here there is ZERO chance to resist.
So again, I can resist a Dragon knocking me down, but not a spider?
100% hit chance, with ZERO% resist chance = annoying cheese attack.
I think scattershot is another of these cheese attacks. Auto hit, auto stun. No defense, no resist.
I will add that I don't think this really applies to Revenant attacks, as someone above indicated.
Once my Rogue got defense ~150 and Physical Resistance to 100, I would hold my party back and the Rogue would usually solo the Revenant without getting hit.
It would be Resist, Missed, Resist, Missed from Revenant attacks while I sliced him apart.
It is because special attacks can't be blocked, they are actually "actions" that bypassed dice rolls and turns, auto attacks are actually following turns
Round 1 - your attack score vs enemy defense score
Round 2 - enemy attack score vs your defense score
Actions such as overwhelm, shield bash, ect bypassed the turn
