Skeletons are enemies spawned by Dark Elf Mages, though they may appear independently in Survival Mix Mode or the Halloween Spooktacular! challenge.

Behavior[]

Bringing a skeleton down to zero health does not permanently kill it; instead it will fall to a pile of bones. Killing the Dark Elf Mage who summoned it will permanently kill all skeletons summoned by him.
Independent skeletons (seen in the Halloween Spooktacular challenge and Survival Mix Mode) temporarily die twice before permanently dying a third time. They resurrect themselves several seconds after dying the first two times.
Each Dark Elf Mage may spawn up to three Skeletons. As long as the parent Dark Elf Mage is alive, it will revive any fallen Skeletons, including any nearby ones.

Strategy[]

Because skeletons do not permanently die unless the Dark Elf Mage who summoned them are killed, it is best to make mages a higher priority than skeletons.
Skeletons laying on the ground still activate traps and consume aura HP. If a large group of skeletons are imminent, ensure that traps and (especially) auras are kept in good repair.
Skeletons when resurrecting are solid and invulnerable until the resurrection is complete. Be wary when charging large groups of enemies; skeletons may resurrect behind you, thus trapping you in the remaining group.
Bowling balls from Bowling Ball Turrets immediately break when hitting resurrecting skeletons.
If a Dark Elf Mage is against a wall and begins summoning skeletons, those skeletons may be summoned past your defenses.
