So I'm interested in playing an NPC I created for my party when I was GMing as a PC for an upcoming campaign. Now, the issue is that he's a Winter Wolf and that's a whole slew of problems waiting to happen so I came up with a good ol' fantasy reason why he's now a PC race: the always useful "I've been cursed" shtick. The thing is I want to simulate some of his winter wolfishness outside of RP with class abilities/powers and I'm not sure what kind of options there are to do that effectively within the rules/outside of homebrewing. Any suggestions would be awesome though I'd like to avoid primary spellcasting classes and I'm open to options that can only be used a limited amount of time. In fact, I'd prefer that.
