voodoo should do something super special awesome if used in combat

pfft, spirits should come down and mudsex your enemies on the spot.

what's your comeback!?

Impregnation.

You counterstrike a shady male humans impregnation
You do UNSPEAKABLE things to a shady male human
A shady male human is dead
You hear a shady male human death cry

You feel different.

Can bards have some sort of concentration boost? Or Combat casting (assuming that it helps with singing/dancing)

Why?

Maxing out your intelligence and dexterity will help you with that. But if you want more than that... well, no. Nothing planned anyway.

The more dex you have, the less int it takes to sing and dance.

Combat casting would be utterly useless to a stock bard (ie: no cabal) because they don't have any spells and get their full third attack regardless of singing / dancing. It would only benefit a caballed bard and even then most cabals don't use their spells in combat.

Why would shamans benefit from combat casting? They only get two attacks and no enhanced damage skill. It's not like they're contributing anything useful to the melee game.
