So I ran into a campaign with a DM that cited this book by name. It's from Mongoose Publishing, and it has literally a ton of feats. (Read: if each feat weight 1 kilogram, you'd get a ton.) Just scouring through the arcane feat section (the feats are all categorized according to which archetype they're appropriate to) I practically had an evilgasm. Couple of notables:
Bloodburn: take Xd6 damage, raise your CL by X. Limit is up to your charisma modifier (and requires you to cast spontaneously too, so obviously a sorcerer feat). Keep in mind the feat doesn't reference temporary augmentation as being a no-no.
Bloodcasting: gain a daily spell slot up to the highest level you can cast, take 1d4 Con damage. Hello Naberius dip, how do you do? I'm fine, thank you. And now you have infinite spell slots without going Tainted Scholar or such things. Alternatively, be undead.
Known Spells Focus: Gain bonus spells as spells known. Yours is the charisma that shall pierce the heavens and learn you a freaking ton of spells!
So who else wants to help me devise deliciously broken manners to pulverize what's already torn apart?
