Wyll and Gale are the two that would probably not survive, Gale is getting double killed, 1 for jump scaring and 2 for eating all my magic items like a drug addict, just take him to the spot where our Tavs first wake up after falling and kill him there, if he blows up there, there would be 0 causalities since everyone on the beach is already dead, Wyll however immediately dies if he dares to threaten Karlach.
