I went over my logs and discovered that when my mors-gravis demons bash, they miss. Every time. I searched and found 24 attempts and 24 misses.

I can't give my demons any rafts or anything. So how do I help my demons to bash?

the demon is perfect match to you, are you fighting things a lot tougher than you? If it is too high level wise, or have a really high dex (elves), they might just be damn hard to bash. Need more info on he target to give a better answer.

Elves, humans, Arials, Giants, Gnomes, mobs, people

it can't bash anything.
