This guide details how to use the Volcano Forge in Stardew Valley 1.6, including forging weapons and enchanting tools. All functions require Cinder Shards, obtainable by mining nodes, enemy drops (Magma Sprite, Magma Duggy, Magma Sparker, False Magma Cap), or from a fishing pond with at least 7 Stingrays. Note: Cinder Shards cannot be created in a Crystalarium.

After achieving Combat Mastery, craft a Mini-Forge: 5 Dragon Teeth, 10 Iron Bars, 10 Gold Bars, 5 Iridium Bars. This functions identically to the Volcano Forge.

Weapon Forging: Weapons (not tools) can be forged up to three times using gemstones and Cinder Shards (10, 15, then 20 shards per forge).

Unforging (red X) restores the weapon, recovering some shards but not the gemstone.
Infinity Weapons: Upgrade Galaxy Sword, Dagger, or Hammer using 3 Galaxy Souls (20 shards each). Galaxy Souls are obtained from Mr. Qi (40 Qi Gems), Big Slimes, the Island Trader (10 Radioactive Bars), or as rare drops from Dangerous Monsters (after killing 50).

Enchantments: Use a Prismatic Shard and 20 Cinder Shards for a random enchantment on any melee weapon or tool. Re-enchant for a different effect.

Weapon Enchantments: Artful, Bug Killer, Crusader, Vampiric, Haymaker. Bug Killer and Crusader are generally most useful.
Innate Enchantments: Use a Dragon Tooth for guaranteed enchantments (Slime Slayer, +Crit Power, +Attack, +Speed) and a chance at a second enchantment (Slime Gatherer, +Defense, -Weight).
Tool Enchantments: Twelve enchantments, tool-specific. Examples include Auto-Hook (fishing rod), Bottomless (watering can), Efficient (various), and Reaching (various). Choose based on playstyle.
