Quick question, I'm running a mage in my current campaign and a bit of an illusionist/aoe shooting guy. As much as I can try to coordinate moves to avoid teammates, sometimes they just get so .. "mucked in" I feel its hard to use my moves to assit, as I dont want to consistantly hurt my own team. I seem to recall that there was SOME feat that was like "Choose X squares IN your blast effect to not happen" or somthing in that spirit.
If that dosent exist or I need to explain further, please let me know! Thanks!
