The Animal Devotion feat also gives anyone a poisonous bite attack for 1 min/day, though it would probably take a generous DM to allow it to work with venomfire.
Well, my DM pretty much lets me do what I want if say it's legal because I know the rules far better than him. So I tend to take strict interpretations of the rules, I don't want to abuse the trust
What DeST said about the wording of Venomfire kind of busts my hustle a bit, the spell does have some interesting phrasing. I think the Hydra trick is right out.
I like the Yaun-Ti fang graft. By strict RAW I am iffy on using it with Venomfire, but it meets the prereq for Spit Venom and opens up that feat chain. If I can't find a better alternative, it will do. A non-level adjustment template would be better though, so I can still keep caster levels and use Venomfire/Spit Venom in normal form. Anyone know of such a thing?
