I know...you can say there is allready enough paths for wizards...but I simply love this one...

1d10/1d12 hp level progresion

Class level bonus on concentration and heal..

Your caster attribute becomes constitution..

Your spells cost life co cast (spell circle*2??)

You gain DC bonus based upon how much HP you have remaining..maybe 1DC per 10% HP?

You can infi cast spells of 1-4 circle (5/10/15/20 level?)
Or you could infi cast all spells but it could cost you way more life...maybe 1-3 : 2*spell level,
4-6 : 3*spell level, 7-9 : 4* spelllevel..

Blood Mage has become relatively common in D&D homebrew settings, and seems a solid idea.

I'm not going to comment on the mechanics you have suggested, but should a developer here want to try working on a Blood Mage class they have my blessing (It will just almost certainly differ from the above)

Anyone interested can google the class and see a number of possible variations.

Approved.

We now have a hemomancer, I consider this complete.
