How to defeat a Tremortusk in Horizon Forbidden West?

How do you defeat these mammoth-like machines?

Tremortusks are one of the most difficult and dangerous enemies in Horizon Forbidden West. They deal massive damage to players during battle and can kill their opponents in only a few hits. The best way to tackle a fight with a Tremortusk is to focus on attacking its most vulnerable parts.

Its Blaze Sac, located on its stomach, will explode and deal massive damage to the machine when hit enough times. Players can also attack and remove the Tremortusk's Plasma Cannon and Tusks, which are responsible for some of the machine's most powerful attacks. Removing these two body parts will disable the attacks.

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 Tremortusk is a part of the KAPPA Overrides Cauldron.
