The Devourer Hydra

The Devourer Hydra is a reptilian creature with many mouths and a large central eye. It uses its arm-mounted mouths as its primary method of attack, but uses its more damaging central mouth when up close to the player. A red overlay will be displayed whenever the player is in its direct vision.

Behavior
Although appearing to be menacing, the Hydra is passive and useless for most of the time. For 40 second intervals it will wander mindlessly. But once that time runs out, it will actively pursue the player and try to kill them for 20 seconds. After that runs out, it will return to the beginning of the cycle and forget the player. The 40 second intervals give the player time to get as far as possible from the creature, as once it runs out, they are placed in a boatload of trouble. Alternatively, the monster can be lured into its 20 seconds immediate anger if it is attacked in its passive state.
