Hostiles (overview)

General Info
All (but one) Hostiles can be categorized by three movement speeds: slower than the player, as fast as the player, and faster than the player. The player can perform one action (such as moving one tile or opening a door) every in-game minute. Creatures slower than the player perform one action per minute for three minutes then halt for one minute and repeat. Creatures faster than the player perform one action per minute for three minutes then perform two actions for one minute and repeat.

The only differing Hostile is the @. It follows the player regardless of whether the player is moving or stationary. It is the only creature that can move even if the player is not taking actions.
