Sorry, I keep forgetting a lot of people on here still haven't read Welknair's Bloodlines. To clarify, I was talking about those.
A bit trickier. Partly because there are waayyy more Monsters than there are half-blood templates, and it would be a nightmare to cover them all. Were you hoping for anything in particular?
Just a general monster class progression. Maybe just get the class features of certain monster classes along the way, without replacing racial features. To clarify, I mean these monster classes.
