Very solid update to Sorcerer. Mostly focuses on the usual M20 effort of compiling all the aspects of a given thing rather than introducing new parts but it's still a very handy guide with a few updates. It's well organized and very streamlined. The more time I spend poking at it the more I like it and they're already working on the errata to deal with the few major issues it has.
Those of you who have always been vexed at things like Giovanni supposedly coming from mortal necromancers yet the mortal necromancy either being non existent or awful will be happy to find several paths related to it in here that are pretty decent.
This does feel a bit lower power than previous editions of Sorcerer so if you're looking for that you may have to tune things up but the rules clarification and consolidation are definitely worth a look. I'd give it 5 stars but I think they can (and will) do better when they update it so I'll save it for then.
