Stardew Valley weapon forging guide: How to use, Infinity weapons, and more

Stardew Valley weapons can be upgraded to make everyday tasks faster, combat more efficient, and resource-gathering easier. These upgrades can be applied using the Forge in the Volcano Dungeon. Thanks to the Forge, you can have an axe that never needs repairs, a sword that has an increased chance to deal critical hit, or a pickaxe that mines with more efficiency.

In this guide, we will cover how to unlock Stardew Valley weapon forging, the different types of upgrades available to each weapon, and the best ones for combat.

The Forge becomes available after reaching the Volcano Dungeon on Ginger Island. Once you make your way to the 10th floor, you'll find the Forge, where you can use Cinder Shards to upgrade your tools.

Stardew Valley weapon forging significantly boosts your abilities, allowing you to explore deeper levels of the dungeons with greater confidence.

If you defeat enemies within the Volcano Dungeon in Stardew Valley, there is a chance that Cinder Shards will drop. Magma Duggy, Magma Sprite, Magma Sparker, and False Magma Cap have a 40% to 50% chance of dropping a single Cinder Shard.

Cinder Shard can also be obtained by mining Cinder Shard nodes with a pickaxe. The likelihood of finding Cinder Shard nodes increases in deeper levels of the dungeon.

With your Cinder Shards in hand, you can head to the Forge and begin forging. Forging requires a certain amount of Cinder Shards and a gem. Here’s a list of each gem and its effects:
