Constructs
Very similar to Rock Trolls, Constructs are large enemies that move very slowly. They should be out maneuvered and destroyed from a distance to avoid taking a significant amount of damage. Sometimes avoiding them is your best option.

Flesheaters
Zombies; strangely, these can bleed.

Grave diggers
Small enemies that run around and dig up undead enemies. If left alive, they will continue to uncover a large amount of enemies (unlimited?).

Skeletons
Melee units that spawn during triggers where doors open on a platform above where your character is standing.

Spider
Large arachnids. Some spit acid. If these appear during a trigger, they come out of sewer grates in the wall.
