The Riftforge
The Riftforge is a smithy off the Rift Spire camp (the north-east branch of the lobby), run by Brann Ashforge, the Riftsmith.
Talk to Brann, or right-click a smithing table in the smithy, with the armour piece in your main hand. /forge shows your materials
anywhere.
Riftforging a piece
Section titled “Riftforging a piece”- What: a diamond or netherite helmet, chestplate, leggings or boots, exotics included.
- Cost: 50 Cinders + 10 Rift Shards per piece.
- The piece keeps its enchantments, name and durability, and gains three mod slots: one Stat slot and two Perk slots.
- It starts at Masterwork 3, which means Energy 3.
- Dungeon set armour from Normal and Hard drops already Riftforged.
The item shows its state, for example:
Riftforged · Masterwork 6 · Energy 5/6◆ Plating II◆ Sure Footing◇ empty perk slotEnergy and masterworking
Section titled “Energy and masterworking”Every mod costs Energy. The total cost of a piece’s mods can’t go over its Masterwork level (3 to 10). Raise it by masterworking with Rift Shards, boss cores and Ascendant Alloy:
| Masterwork | Rift Shards | Boss cores | Ascendant Alloy |
|---|---|---|---|
| 3 → 4 | 20 | - | - |
| 4 → 5 | 30 | - | - |
| 5 → 6 | 45 | 1 (any floor 1-5) | - |
| 6 → 7 | 60 | 2 (any floor 1-10) | - |
| 7 → 8 | 80 | 2 (floors 6-10) | - |
| 8 → 9 | 100 | 3 (floors 6-10) | 1 |
| 9 → 10 | 150 | 4 (floors 6-10) | 2 |
| Total per piece | 485 | 12 | 3 |
A Masterwork 10 piece also gets +0.5 armour toughness and a gold line on the item.
Materials are kept on your account, not as items, so they can’t be lost, dropped or traded. See Cinders and Rift Shards for where they come from.
Mods are items. Slotting a mod uses it up, and replacing or removing a slotted mod destroys it (the menu warns you first).
Mods can be traded with /trade, sold in chest shops and kept in backpacks, and they stack to 16.
Tiers show by name colour: I white, II aqua, III gold.

How mods drop
Section titled “How mods drop”- First clear of a Spire floor: one mod from that boss’s list, guaranteed.
- After that: a 20% chance at a mod from that boss’s list, rolled at most once per boss per day (in a climb or a rewarded rematch).
- Cinder Colossus win: Siphon or Scavenger, guaranteed.
- Hard dungeons and Rift Trials can drop a mod from the vault.
- Brann sells the tier I stat mods (Vitality I, Plating I, Tempered I, Might I, Swift I) for 40 Cinders each.
Across all four armour pieces, mods can add at most:
| Stat | Cap |
|---|---|
| Max health | +4 hearts |
| Armour | +6 |
| Armour toughness | +4 |
| Attack damage | +3 |
| Movement speed | +12% |
Riftbane, Bulwark, Second Wind, Siphon, Scavenger and Foresight count once, even if slotted twice. Vanilla’s own limits still apply.
Salvage
Section titled “Salvage”Brann breaks spare mods down into Rift Shards: tier I 5, tier II 10, tier III 20 each.
Good to know
Section titled “Good to know”- Mods count in duels.
- Mods only work on Main, never on Anarchy.
- Upgrading a Riftforged diamond piece to netherite at a smithing table keeps its mods and Masterwork.
