Lost Ark Ability Stone Faceting odds

Faceting works an Ability Stone one slot at a time on its engraving lines. Each attempt succeeds or fails at the current Success Rate, and the chance changes after every success and failure; the successes on each line set the engraving levels the stone grants.

Faceting in the game

1. Talk to a Stone Cutter and choose Facet.
2. Choose the stone, then facet one line at a time; the window shows the current Success Rate.
