In the absence of a Squirrel Contaminated use Macabra Puppet with 1, 2, 1 starting with Life Suction and then throwing the Dead Party, in that order of priority, at the end Vahofetido enters or any undead that removes more than 253 hp at a stroke. =)
Blighthawk 1, 2, 1; Infected Squirrel 2, *, 1; Blightbreath; *, 2 *. For Blighthawk, use Infected Claw, Lift off, and only use ghostly bite in the undead phase. Infected squirrel, healed once after stampede. I wanted to try creeping fungus before stampede but forgot. Might be better.
Simple script for Son of Sethe, Blighted Squirrel, Blightbreath

You have to get really lucky with Son of Sethe against Delta for this strat to work. You need no crits by Delta, no triple-thrashes and Lift-Off has to hit high enough. Otherwise Son of Sethe gets killed by Delta.
