What do they look like?
Does their fur or hide blend into the environment? Are they scarred, diseased, radiant, or puzzlingly pristine?
How do they move?
Fast and skittering? Heavy and lumbering with the sound of cracking stone?
Drifting, floating, or phasing through shadows?
What stands out?
Extra eyes or ears might reveal unseen threats or ignore stealth attempts. Oversized claws might break shields or leave jagged rents in stone walls. Strange colors or glowing organs might hint at venom, radiation, or magic.
Why do they fight?
Hunger? Territory? Vile purpose? Self-defense?
Creatures behave with instinct or intent. Let those motivations guide their tactics.
