Muddle Buds - I like that they are in game, it's more or less Confusion spell, it gives you a tool to tackle the problem differently than heads on approach. What I didn't figured out so far is if monsters have anything akin to Wisdom/Will Saving Throw (to put it into D&D terminology) that will be checked in the background to decide if they are influenced by it?
Haven't get around to try it on all different enemies, but so far it seems all that I tried on were susceptible to it...any other experiences so far?
