My character (who is not a Monk and does not have Improved Unarmed Strike) has just learned a touch attack spell (Chill Touch).
1) Can Magic Fang give a +1 to hit with this spell? I think so (the spell says "fists", Chill Touch says "hand") but I suspect the intent is that I would have to then deliver the attack as an unarmed strike (with the associated AoO, full-AC instead of touch-AC, and, in my case, damage penalty for STR).
2) How about the +1 damage from Magic Fang. This, I suspect, really needs an unarmed strike.
3) Can I "fight defensively" with it? SRD says "when attacking". I think I'm on safe ground in saying that a touch attack is an attack?
