Sorc Pyromancer , yeah that's Blaster 101 for noobs right there.
Fluff (tho' interesting) on which classes are available is near totalsvckballs. Too setting specific for my tastes.
Int Arcana has 2 minor crunch things on page 11.
Buying Selling --- appropriately B S
--- isn't quite the same as in the DMG.
CARS COST 100 G.P. ?!!
Quicksmithing feat = Ritual feat with minor recrunch/fluff.
Servo Crafting feat = Find Familiar + missing template (see Servo at the bottom of the pdf) + small attack thingy
Aetherborn = var Half Elf with Major refluffing. I like. Gift Of The Aetherborn = yes please.
Elf like Zendikar minor crunch change.
Vedalkin = var Gnome with Major refluffing. I like. Int +2, Wis +1, for all your Mystic Theurge inclinations.
Gremlins ... oh yeah sic these on a mid level party having never seen anything like this before = Freak Out.
