Sneak Attacks and Carried Effects

[FrodoOf9Fingers]

So, say a rogue has Chill Touch as a SLA.

He casts said spells, and uses the free touch attack to hit someone. We can all agree the sneak attack damage would be negative damage.

ON the next turn, he decides to punch his target, which also delivers a charge of chill touch. What damage type would this deal? Bludgeoning or Negative?

bludgeon. The main weapon is now the unarmed attack. The spell is a extra thing. Similar to a normal sword + flaming quality.
