Rune Leveling
Runes are leveled by feeding duplicate copies. Each level increases the rune's bonus. Only one rune can be equipped at a time, so choose wisely.
Usage Tips
- •Luck runes are essential for farming builds to maximize drop rates from bosses.
- •Swap to a damage rune for boss fights where you need DPS, then switch back for farming.
- •Only one rune can be equipped at a time. Prioritize leveling your primary rune to Lv50 before investing in others.
