I think the penalty for dying is too harsh. Maybe like when you die, you loose some experience points and you can be ressed but the weakness debuff would be more severe and longer.

Mmm....I can imagine it now from those Shasta final boss trash mobs popping twice as fast...stone Virgil final boss the ice dragon using his mechanics twice as fast all the way to av's final boss super quick bad breath and germinate
