My first one came to me as I threw a kiss to my wife and accidentically in the same moment she dropped her sandwich on the ground. Needless to say on which side it landed, hehe.
So the idea:
Disturbing/unarming kiss: based on charisma? it could be a touch spell or skill, or ranged with very short distance. If succesful the same effect on everyone (m or f). Small success that the enemy won't attack the spellcaster next turn (but can do anything else or attack others) big success that the enemy is so surprised that drops his/her weapon. Next turn it cost many ap to equip another weapon or pick up old one.
What do you think? Your ideas?
