Revenant

NeoQuest II boss found in the Lost Desert, part 3 of the game. A mummified Kougra, the Revenant has 600 hp and is also paired with 2 possessed skeletons, each of which has 180 hp. Despite that the Revenant can heal all of his members 60 hp in one turn and does 44 group damage to enemies, he isn't too difficult to defeat because Velm can heal the player's group so the health wouldn't be a concern.
