Something like this build.
Chaotic evil barbarian
Flesh crunch with +6 Strip the Flesh (the other boost doesn’t matter).
Flame of the Fire Hawk
Inflammable The Bee (for the fire dude)
Flakker (for the fire dude)
A fire Interfacer
Magic Missile x 4
Grog Nozzle/Rubi
A accurate weapon to make the dragon of your choice land without antagonizing the others.
