Ghouls fulfill a similar role to Zombies from previous games, but have faster movement and attack speed. They are blue-skinned undead who spawn in great numbers, are quite fleet of foot and quick of movement, but are fairly weak and easy to kill. While ghouls often fight empty handed, some have been seen wielding swords. At many times, they will climb up the walls to ambush the player. In Acts I and II, normal Ghouls are encountered, but in Act III, Blazing Ghouls (which are more powerful and deal additional Fire damage) replace them.
