Refining

Adding permanent DC, MC or SC to a weapon at the refining NPC

How it works

Hand a weapon to the NPC along with ingredient items and Black Iron Ore, pay a gold fee, then come back later to collect it. The ingredients decide which stat is added and heavily influence the chance of it working.

Which stat you get

Every ingredient's DC, MC and SC are totalled separately (min + max, plus anything already refined onto them). Whichever total is highest is the stat your weapon gains. Items carrying no DC, MC or SC are ignored entirely, and weapons cannot be used as ingredients.

Success chance

Four parts added together, then reduced by refines already on the weapon. The best possible score is 100%.

SourceMaxHow it is earned
Base+20%Always given
Ingredients+35%Up to 10% from their stat total, +10% if their average required level is high enough, +10% if all are at full max durability, +5% if all are fully repaired
Ore+35%+15% for at least as much ore as ingredients, +15% for high enough average purity, +5% if total purity exactly matches the stat total
Luck+10%Weapon's Luck + 5
Penalty−50%Every point already refined onto the weapon costs 6%, capped at 50%

Ore purity is that ore's current durability divided by 1000. Add no ore, or no ingredient carrying DC/MC/SC, and the chance is zero — the attempt is wasted.

Collecting

The roll happens when you collect, not when you hand it in. On failure the weapon returns unchanged: the gold and materials are lost, but the weapon itself is never destroyed or downgraded.
