Ah ok, but since he is bound to escape if we don't act now (and this was our plan all along, to capture him at the party), we have to act now.
I'd handle it as an untrained exotic weapon attack (AGI -1 as I rolled) with airburst rules
Tabasco won't be as strong as pepperpunch so I'd say 2/3 or half of its power
Likewise for the improvised fire breathing against a hopefully distracted target. That one's mostly designed to set his cloths on fire and force him to divest himself of his jacket.
A cyber troll, a cyber elf and a mage, and an adept should be able to overpower him.
The explosions should have distracted the security enough that they won't stop us "evacuating" him.
