Speed order: CLS, Han Solo, Chewbacca, C-3PO, Old Ben
All need to be r5 or higher with most of the zeta’s required.
Go for alot of speed secondaries so CLS gets 310+ , han solo 270+ etc
CLS and Han need the lowest hp+prot so they get guard
Strategy: Topple GAS asap. When he takes cover try and kill them all, 5’s first,then rex, then echo and finally arc trooper. If needed, topple again. Use chewbacca’s pulverize to get rid of buffs and use ben’s devout protector just before GAS comes out of cover to tank up any damage.
