Enhancement Mechanics & Methodology
0 to 30 Failstacks
Direct Black Stone Exchange: Black Stones can be consumed directly at the Enhancement interface for fixed stacks (5 FS = 5 stones, 10 FS = 12, 15 FS = 21, 20 FS = 33, 25 FS = 53, 30 FS = 84).
Reblath +14 Failstacking: Reblath Armor from Velia blacksmith Tranan Underfoe has a 2% base success rate (+0.1%/FS). Failures grant +1 FS and cost 1 Black Stone + 6,300 silver repair. Accidental +15 successes are cleansed at the church for 100,000 silver.
30 to 50 Failstacks
DUO → TRI Green Gear: Attempting DUO → TRI on Grunil or Heve armor grants +4 failstacks per failure and consumes 1 Concentrated Magical Black Stone (Armor).
Dragon Scale Fossils: Exchanging 350 fossils yields an Advice of Valks (+40), and 450 fossils yields an Advice of Valks (+50).
50 to 100 Failstacks
TRI → TET Boss or Green Gear: Attempting TET enhancements on TRI gear grants +5 failstacks on failure. Restores durability with Memory Fragments or base green gear.
100 to 300 Failstacks
Origin of Dark Hunger: Applied between 100 and 299 FS according to Adventurer's Guide diminishing return curves (+26 at 100 FS down to +1 at 299 FS). 100% success rate, 0 durability loss, maximum base stack of 300.
