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

  • Damage runes are the most versatile choice, boosting all damage output universally.
  • Pairs well with high-DPS fruits and swords for maximum burst damage.
  • DoT (Damage over Time) runes provide sustained damage, great for extended boss fights.
  • Less effective in PvP where burst damage is preferred over sustained damage.
  • Only one rune can be equipped at a time. Prioritize leveling your primary rune to Lv50 before investing in others.
