So I've been tweaking some of the 3rd party Pathfinder classes that seem a little bit broken. First one is the Dragonrider by Super Genius Games.
Tried to balance it as I saw fit. Gave it the Magus' BAB and spell list, and nerfed it's absurd save bonuses. Also tweaked the built in multiclass options to make it a little more interesting.
Would like to get some feedback from players more experienced than myself. I uploaded the 'fixed' version here.

Can anyone recommend additional resources to use with the Inscribe Magical Tattoo feat? The 3 'stock' tattoos from Inner Sea Magic seem a little underwhelming and the book is pretty vague about additional uses for it. Was hoping there were some 3rd party or 3.5 books with reasonable rules for homebrewing magic items that would translate well for this purpose.
