Infernal Artifacts League/Artisan's Forge
Melt and Improve are the first two functions of the Artisan's Forge in the Infernal Artifacts League. Both unlock at League Tier 1. Melt destroys unwanted affixed gear for materials. Improve spends those materials to raise the affix values on gear that you keep.

Overview
To open the Forge interface, use the Demonic Anvil. The interface has four tabs:
| Tab | Unlocks at | Function |
|---|---|---|
| Melt | League Tier 1 | Destroy items for materials. |
| Improve | League Tier 1 | Upgrade affix values on items. |
| Transplant | League Tier 3 | Move affixes between items. |
| Masterwork | League Tier 5 | Final affix boosts. |
The top-left corner of the interface shows your material totals in this order:
Melt

The Melt tab breaks down affixed gear into Forge Dust, Forge Cores, and Upgrade Gems. Melted items are destroyed.
How to melt items
- Use the Demonic Anvil and select the Melt tab.
- Stage items in the crucible with one of these methods:
- Click individual items in your inventory.
- Click a Bulk Add By Rarity button to add every item of that rarity, or click All.
- Check the Estimated Yield line at the bottom of the interface.
- Click Melt X Items.
- Click Confirm Melt in the confirmation window, or press Enter or Space. To cancel, press Esc.
To empty the crucible without melting, click Clear Crucible.

Yields
Each staged item shows its own yield. The video shows the following yields for adamant and rune platebodies:
| Rarity | Forge Dust | Forge Cores | Brimstone Thread |
|---|---|---|---|
| Epic | 60 | 0 | 1 |
| Legendary | 120 | 0 | 1 |
For example, seven Epic platebodies melt into 420 Forge Dust, 0 Forge Cores, and 7 Brimstone Thread.
Brimstone Thread is a separate resource that trims skilling outfits.
Demonic powers

Items that carry a demonic power show one of two labels in the crucible:
| Label | Meaning |
|---|---|
| Unbanked Power | You have not extracted this power into your Demonic Codex. |
| Already Banked | This power is already in your Demonic Codex. |
The interface also shows a warning that counts the staged items that carry demonic powers.
Improve

The Improve tab spends materials to raise the value of an affix on an item. You do not need a perfect roll when an item drops. If an item has the affixes you want at low values, improve them.
Affix tiers

- Each affix progresses from Tier I to Tier V.
- Each tier has 10 micro-steps.
- Upgrades have a 100% success rate. Upgrades never fail or break your equipment.
- Costs scale with tier. Low tiers require Upgrade Gems and Forge Dust. Tier IV and Tier V require Forge Cores.
- An item can have a tier cap. For example, a Level 40 Legendary rune platebody shows Affixes cap at Tier II.
How to improve an affix
- Use the Demonic Anvil and select the Improve tab.
- Click an item in your inventory.
- Select the affix to upgrade. Each affix row shows its current value, its value range for the current tier, and its tier and step.
- Check the Current and Projected values and the Step Cost.
- Click the upgrade button. If you lack materials, the button reads Need Materials and the missing material appears in red.
If an affix rolled more than once on an item, each roll appears as its own row.
Example
| Item | Affix | Step | Current | Projected | Step cost |
|---|---|---|---|---|---|
| Legendary rune platebody (Level 40) | Damage reflected [30 – 40] | Tier I, Step 3/10 | +32.55% | +33% | 166 Upgrade Gems, 140 Forge Dust |

|---|---|---|
