Storm Weaver is a craftable katana in Loot to Forge. Getting it starts with selecting the right ores at the Forge, then claiming the finished weapon.

How to get Storm Weaver in Loot to Forge
Forge and equip Storm Weaver first, then add runes and enhancement upgrades to develop the weapon further.
Part 1 – Forge and equip Storm Weaver
Abyssal Blue and Magma Cluster appear to become obtainable from stage 9 onward.
Approach the Forge cauldron
Walk to the large suspended cauldron at the center of the town square. Look for its Forge interaction prompt.

Open the Forge menu
Your inventory ores appear on the right; before you add any, the preview reads Katana: 0%.

Load the Storm Weaver recipe
Add 1 Magma Cluster, 1 Abyssal Blue, and 2 Frostbite ores from your inventory. The interface has four slots, and the two Frostbite ores can appear together as an x2 stack, leaving one slot empty.

Start forging
Click Forge at the bottom of the screen to begin crafting.
Let the forging animation finish
Wait while the cauldron melts the ores and pours the metal into a mold. The ingot moves to the anvil for hammering into a blade, then cools in the water tub.

Claim Storm Weaver
Review the Storm Weaver reward card when forging finishes. Click anywhere to advance past the card and claim the weapon.

Equip Storm Weaver
Close the Forge window and leave the structure, then open Backpack. Select Storm Weaver and press Equip; afterward, you can test the weapon and activate its skill in the plaza.

Part 2 – Add runes and enhance Storm Weaver
Add rune enchantments and enhancement upgrades after you’ve obtained the weapon.
Apply Thunder Rune I
Visit Enchant and select Storm Weaver. Choose the lightning tab, select slot 1, and apply Thunder Rune I with Enchant.

Enhance the weapon
Review the weapon after upgrading.

Apply Poison Rune I
Return to Enchant and reopen the Enchantment menu for Storm Weaver. Choose the poison tab and second rune slot, apply Poison Rune I, then close the menu.

You can let the forging animation finish without buying a skip. Skipping the forging animation costs 29 Robux.
