Don't know, I just like stealth, and my character has hid from others for a long time now, so he needs to be good in blending in. Also, if your power is to summon and control guns, you need to have some extra side-skills if you want to survive.

EDIT: I agree on the 'no anti-venom' thing. Maybe you should make it that there is a vaccin for it, making you temporarily immune to it, but you need a sample of the saliva in advance to be able to make it.
