My game has a dove shaman who is really no good in combat (just after) and wants to be more useful. Also, she has fallen in love with and married the troll

. The player wants to know if she can slough off the karma costs of quickening big increase attribute/initiative spells to other PCs. I don't think he (the player) really understands their drawbacks, but that's a whole other issue. Does she have to pay all the karma, or can another PC pay the karma especially when it benefits the other character directly? I guess we could use karma for cash for karma, but that would wreak the roleplaying mood he is going for.
