Grimhorn are extremely dangerous foes in Horizon Forbidden West. They are a modified version of the Plowhorn that is made to fight with extreme aggression. An easy way to get an advantage in a fight against a Grimhorn is to take out their Horns first. This will massively reduce the effectiveness of their Fire elemental attacks and make the rest of the fight much easier.

Cauldron

In Horizon Forbidden West, Cauldrons allow players to override the machines within that Cauldron once they have completed it. Completing a Cauldron usually means traversing through its dungeon-like corridors and facing off against a boss at the end. The Grimhorn is a part of the TAU Overrides Cauldron.
