The Forge: Refine and +10

Refine materials

Refining uses stones: Orichalcum from +0 to +6 and Lactorium from +6 to +9. They drop from monsters and also form from dust: 10 dust become 1 stone (on their own, with Auto-combine dust on).

Materials

Material	Description
Orichalcum Dust	Golden dust scraped from discarded and duplicate items. 10 Dust combine into 1 Orichalcum.
Orichalcum	A golden refine stone pressed from Orichalcum Dust. Refines from +0 to +6.
Lactorium Dust	Blue-silver dust carried by the strongest monsters. 10 Dust combine into 1 Lactorium.
Lactorium	A blue-silver refine stone pressed from Lactorium Dust. Refines from +6 to +9.
Sage's Stone	Catalyst for +10. Each attempt consumes one, on success or failure.
Sapphire	A blue gem, cold to the touch.
Emerald	A green gem that pulses slowly.
Coral	A pink gem taken from the depths of old vaults.
Garnet	A dark red gem, warm like an ember.

• Orichalcum Dust also comes from discarded items (1 dust) and duplicate drops (1 dust).
• Lactorium Dust only drops from stronger monsters, from the Shallow Crypt on; the Lactorium stone, from Ashbitter Fort on.
• Drop regions multiply material odds; XP regions lower them.

Refining +0 → +9

Drag the stone onto the item (at the Forge or right in the bag) or place the item in the Forge slot. Each attempt costs 1 stone and gold. On success the item goes up one level; on failure it stays where it is and its failure count goes up. Once the guarantee is reached, that item's next attempt is a sure success.

Refine odds

Step	Chance	Guarantee	Cost	Average attempts
+0 → +1	100%	—	1 Ori + 10 gold	1
+1 → +2	95%	—	1 Ori + 70 gold	1.05
+2 → +3	90%	—	1 Ori + 130 gold	1.11
+3 → +4	80%	after 2 failures	1 Ori + 250 gold	1.24
+4 → +5	70%	after 3 failures	1 Ori + 480 gold	1.42
+5 → +6	55%	after 4 failures	1 Ori + 500 gold	1.78
+6 → +7	45%	after 5 failures	1 Lac + 850 gold	2.16
+7 → +8	35%	after 6 failures	1 Lac + 1,500 gold	2.72
+8 → +9	25%	after 8 failures	1 Lac + 2,700 gold	3.7

The odds are fixed: the XP and drop multipliers in Options don't change refining. The failure count belongs to each item and resets on success.

Composition 4 → 1

Combine any 4 items from your bag — any tier, slot and refine — and get 1 item at +0 with new affixes. Success is guaranteed; chance decides the tier and the piece. The Forge shows the exact odds of every outcome before you confirm.

Result tier

Each item is worth 1 ticket for the tier above its own (I → II, …, VI → VII; VII stays VII) and the result draws one of the 4 tickets:

• 4 tier I items = always a tier II item.
• 3 tier I + 1 tier II = 75% II, 25% III.
• 4 tier VII items = a tier VII item with new affixes — the way to reroll top-tier affixes.

Result type

• 3 or 4 weapons: a weapon for your class.
• 0 or 1 weapon: armor, a shield or an amulet.
• 2 weapons and 2 other pieces: you choose at the Forge.
• Directed composition: with 1 gem of any kind, you pick the result's slot (Chest, Helm, My class's weapon…); the tier is still drawn.

The 4 items are consumed. Equipped and starter items can't be used. Auto-Compose combines bag items 4 by 4 for the classes you tick — never equipped, locked or favorite ones.

+10 with gems

+10 merges two identical +9 items into one, which gains +10 stats, merged affixes and the gem's effect. Gems drop from monsters from Ashbitter Fort on; Sage's Stones, from any region boss and from monsters in Oathwaste and beyond.

Items

2 identical (the same item) at +9

Gems

4 of the same kind

Catalyst

1 Sage's Stone + 30 Lactorium

Chance

40%

Guarantee

after 3 failures (account-wide count)

Average attempts

2.18

1. The 1st item becomes +10 — it can be equipped. The 2nd, from the bag, is consumed on success.
2. On failure: the gold, the Sage's Stone, the Lactorium and the 4 gems are lost; both +9 items stay intact.
3. The affixes of both items merge by grade: 90% the same grade, 6% one lower, 4% one higher.
4. Amulets can't go to +10.

Gold cost per tier

Each gem's effect

The gem you pick defines the effect the +10 item gains, and it grows with the item's tier. The item glows in the gem's color.

Gem effects by tier

Gem	I	II	III	IV	V	VI	VII
Sapphire Drop rate	+8%	+9.6%	+11.2%	+12.8%	+14.4%	+16%	+17.6%
Emerald Penetration	+40	+48	+56	+64	+72	+80	+88
Coral XP rate	+2%	+2.4%	+2.8%	+3.2%	+3.6%	+4%	+4.4%
Garnet Absorption	+40	+48	+56	+64	+72	+80	+88

• Sapphire: more drops — for farming items and materials.
• Emerald: Penetration — strips target defense before every hit.
• Coral: more XP — to level faster.
• Garnet: Absorption — cuts a flat amount off every hit taken.
