I did some more research. (also thought his skill was Rngless!)
Solutions on the field other then going for the kill:
Aano (restore Atk),
Folrart Slash Knight (restore 1 friendly HP=0),
Etiole (restore all friendly HP=0),
Aliria (restore 10HP all friendly closeskill, revive 1 friendly autoskill),
Women of purity (revive 1 friendly closeskill), <-- needs to close AFTER things are dead, not simultaniously.
Obsidian Carbuncle (heal or revive 1 Carbuncle closeskill),
Boy combat priest (heal 20MHP 1 TGC closeskill),
Justice (heal 10HP closeskill), Phoenix Chick, Morning Lycans & Ashbar (self-revivers),
Gilensa, Guardian Sphinx. (revive friendly unit(s) actionskill)
Sunbeam, Inquisition Night Raider (during nighttime), Fortune. (remove Rng)
Most probably suck tho. Best to kill it when you get the chance....
