Īlpha creatures are the second tier of tameable creatures that Primal Fear adds to your game. When harvested Toxic Creatures will drop Toxic Blood and Toxic Hide. Toxic Creatures have a 7% chance of spawning. Their loot tables include vanilla items with the occasional Tame Helpers, Primal Stimulants, and Potent Narcotics. They have a mere x3 stat multiplier and can deal torpor damage, compared to vanilla creatures, yet they are vital in progressing through the tiers, as you will need their blood and eggs to progress to the Alpha Creatures.
They require Toxic Kibble to tame, which can use any egg. Toxic creatures are the first tier of tamable creatures that you will encounter.
