The mechanical beauty of the forsaken portal ability was just so god damn cool. It needs to come back.

I would like to see some way for them to open rifts to a force of pure wild magic that can alter reality in the world around. Either make it a straight up skill or make it a possible outcome of using any entropy powers.

Portal could do all sorts of stuff.
-spawn beer elementals from alcohol containers
-reverse magic affects (damn redux becomes soften, reduce becomes enlarge, frenzy becomes calm etc.
-randomly do mirror image on people in the area
-boost magic like a veil tier weaker in that area. Maybe max tier in same room.
-spread insanity to non mages
-turn people into toads
-freeze/set rooms on fire/make air poison
-cause orderly people to feel ill and vomit in its presence
-reverse all directional commands
-conversely the affect could be like a cloud spell instead of area wide like portal. Extra points if calling magic through it fuels it more and it has tiers of affects based on thinness of veil.
-animated nearby corpses
-change the weather
-start a magical plague
-random neat stuff
