If you want to heal with fire, there's always Phoenix Belt. Set yourself on fire for continuous fast healing 1.
I am completely unfamiliar with Soulmelds. How do they work and how could I get such a belt?
Are you suggestimg taking a level in Totemist? Also, is there a way in which I could obtain the belt without having that class?
Also, how does having this give me fast healing?
Phoenix Belt, when bound, gives you fast healing 1 whenever the fire resistance it grants prevents fire damage, for a number of rounds equal to the fie damage prevented.
You can use a feat to get the soulmeld, and another feat to bind it, though the later wouldn't kick in until level 18... better off getting a spell that can open the chakra for you.
