Their horns spew out various fire-based attacks so getting rid of these will take away their primary offensive capabilities and save yourself from being burned. This component can be separated using Tear damage to be looted as a resource to upgrade your weapons and outfits, if you don’t separate it before Grimhorn is killed the horns will be lost.

This is where the fuel for their fire attacks is stored and explode if you damage it enough. Now there is a dilemma to this weak spot, either you destroy it to use its explosion to deal massive area damage and stop the fire attacks or you save it until the Grimhorn is dead to loot it for resource. The choice is yours!

Cluster Launcher

This component gets annoying if you are trying to stay at a distance to deal with this monstrosity. It will rain down cluster bombs at you and deal substantial damage. Although it’s their asset to make your life hell, it can be removed and used by Aloy to flip the table and used against the giant, even after Grimhorn is downed these weapons can be picked up and used.

Tail Clamp & Tail Capsule

If you shoot the Tail Clamp, in the left picture, the tail will be immobilized and tail attacks will stop momentarily. Furthermore, doing so will open up the Tail Capsule, in the right picture, which contains a bunch of valuable resources. These resources can only be accessed while in a fight, otherwise, if Grimhorn is destroyed all these will be lost with it.
