Ioprey

A vivid red species of small carnivores often found in subtropical zones. Sacs in their throat contain a powerful poison that slowly drains the Health of their prey.

It forms packs in the Swamp and the Volcano. It moves quickly, and when several attack at once it becomes a troublesome foe. It attacks by spitting poison, so do not stand in front of it. Keep your feet moving and always circle around to its side to attack.
