Buttressed

Buttressed is a material mod in Fallout 76.

Effects
When applied to a raider, trapper, or marine armor piece, it improves Damage Resistance and Energy Resistance. It is considered a fourth-tier material mod for raider, trapper, and marine armors.

Locations
The buttressed material mod may be crafted and applied to raider, trapper, or marine armor at an armor workbench if the relevant plan is known. Note that the mod can only be learned from scrapping armor of the same type (e.g. trapper or marine armor) and yields the automatically-learned mod for a random piece of said armor type.

As with other mods, loose buttressed mods for the raider and trapper armors may be randomly sold by Responder, Raider, Brotherhood, and Free States vendors. Raider mods may also be found in the Toxic Valley, while trapper mods may be found in the Savage Divide and Ash Heap. Loose marine buttressed mods cannot be found in-game.
