I've just started looking through the 5th edition book. It seems like very little has changed with the magic system other than alchemy and ritual casting. Would it be a problem to use 4e street magic with 5? How much house ruling would be necessary? I really would like to be able to use some other traditions, spirits, and maybe possession spirits.

Thoughts?

Drain has changed a bit , to F instead of F/2 plus they changed some of the add ons, but if you look at the spells they have you can pretty much figure what to shift it to.

Not sure how the other elemental effects like sound and sand and the rest from Street are getting tweaked yet, so can not advise on those.
