Rune Power-Up & Substat Enhancement

Learn Rune Power-Up & Substat Enhancement in Summoners War, using Mana Stones, Grindstones, and Enchanted Gems for optimal stats.

Runes can be powered up using Mana Stones, increasing their main stat and unlocking substats at +3, +6, +9, and +12. At +15, the main stat reaches its maximum. Substats can also be enhanced using Grindstones (to increase existing substat values) and Enchanted Gems (to change a substat to a new one). These are obtained from Rift Raids.
