Additional Creatures Wiki

Cornusaurus is a fictional species of dinosaur in Additional Creatures.


Cornusaurus is an apex-level theropod found in various forested environments. Its appearance calls tell to the Wendigo: a cannibalistic spirit in native-american folklore. Just like it, however, it is a ravenous and bloodthirsty creature. Every attack with its jaws or horns bleeds the target, and it is capable of delivering a fearsome roar that can damage the nerves of enemies temporarily: blinding them and hindering their movement. If that wasnt enough, Cornusaurus's sheer presence alone terrifies smaller creatures away from it! However, Cornusaurus lives up to its Wendigo-like attributes whenever it eats a fresh kill. When it does, a strange, Purple liquid called Malignent begins to flow through its veins. Malignent is a form of element liquid, and this causes the cornusaurus to fly into a fury after eating a corpse. When in this "Bloodlust" state, they become much more powerful and durable, becoming a drastic threat. However, if it is unable to keep up its bloodshed, it will enter an exhausted state: becoming weaker and vulnerable for a time. Tamed, Cornusaurus proves to be a fearsome berserker, flying into a fury and rewarding its owner for senseless violence and bloodshed.

Automatically dismounts. The Cornusaurus can also generally be told to sit. This slightly increases healing rate.

Cornusaurus, after harvesting a corpse, enter a Bloodlust state for 35 seconds, which increases damage by 60%, health and stamina regeneration, and torpor drain. Once this state runs out, the Cornusaurus enters an Exhaustion state for 40 seconds or until Bloodlust is activated again, which decreases defense by 15%, damage by 25%, decreases stamina, and gains torpor.

Cornusaurus passively produce Malignment in their inventory during their bloodlust state. Malignent weighs nothing in the inventory of a Cornusaurus.

Cornusaurus have an AoE debuff called "Terrifying Visage" which causes smaller creatures to flee when unmounted and receive a 30% decrease to attack and defense.

Cornusaurus are immune to bleed and radiation.
