How To Upgrade Weapons in Bastion (Full List)

The Forge Upgrade Menu in Bastion

You can upgrade your weapons after unlocking the Forge. You’ll find your first Forge in the eastside of The Workmen Ward. After that, you can then build your own forge when you return to The Bastion.

You’ll have three upgrade tiers at first.

Later in the game, you can unlock the True Forge, which gives you access to the fourth and fifth upgrade tiers.

The earliest you can do that is after getting the Shard in Jawson’s Bog. You can’t miss it since it’s part of the story.

Upgrade Materials

Every weapon has their own specific upgrade material. You need one piece of material for every upgrade tier, along with Fragments.

You can find these materials in proving grounds, the Lost-and-Found, and across various levels.
