Weapon augmentation in Remixed Dungeon refers to the Reforging mechanic offered by the Troll Blacksmith quest NPC. There is no “augmentation” subsystem that adds properties such as Precise, Swift, Heavy, or Light; the only in-game weapon modification beyond upgrading is the reforging service provided by the Blacksmith.

The Blacksmith's reforge combines two items of the same type (same `entityKind`) into a single item whose level is one higher than the higher-level of the two inputs.

• Item kind: Both items must share an entity kind (e.g. two Short Swords, two Leather Armors).
• Identification: Both items must be identified.
• Cursed state: Neither item may be cursed.
• Negative levels: Neither item may have a negative upgrade level (`level() < 0`).
• Upgradability: Both items must be upgradable (`isUpgradable() == true`).

When the reforge is performed:

• The higher-level of the two items is upgraded by 1.
• The other item is consumed.
• The hero spends 2 turns (`Dungeon.hero.spendAndNext(2f)`).
• The `SND_EVOKE` sound is played.
• The `Badges.validateItemLevelAcquired` badge check is run.

• A regular upgrade (via Scroll of Upgrade or Scroll of Weapon Upgrade) raises the level of a single item by 1.
• The Blacksmith's reforge consumes the second item while raising the first item by 1 — the net effect on a single item is identical to one upgrade, but the second item is destroyed.
• For weapons, the Scroll of Weapon Upgrade is the upgrade path that may add or preserve an enchantment; the Blacksmith's reforge does not change enchantments on the surviving item.

The Troll Blacksmith spawns on dungeon levels deeper than 11 (controlled by `Dungeon.depth > 11` in the spawn code). The quest has two alternative paths:

• Gold path: Retrieve 15 pieces of dark gold ore and bring them together with the pickaxe the Blacksmith provides.
• Blood path: Use the pickaxe the Blacksmith provides to kill a bat, then return the blood-stained pickaxe.

After the quest is completed, the Blacksmith will open the reforge window. Once a reforge has been performed, the Blacksmith will only say “I'm busy. Get lost!” until the dungeon is reset.
