Using the mace of 'whatever her name is' causes enemies struck by it to repeatedly halve their attack value. 3 hits took an obsidian golem down to 5 attack.. This effect is unresistable.
Also the fear effect from dragons and other monsters stacks with itself, and can effectively negate multiple turns a row. While I'm sure my units need time to shit their pants, I'm pretty sure once they are soiled and changed, they won't be able to immediately do so again. In it's current form it's pretty rediculous. I'm also fairly certain I have never resisted this effect.
