Actual in-game values may vary from those shown in this document. ## What is Rune? Rune is a new function that increases the power of mongen. Each mongen can equip up to 6 runes at the same time. If equipped with the correct rune type and location, mongen will activate a runeword Runeword when equipped activates special effects. The more rare the runes in the runeword, the stronger the effects of the runeword. {% hint style="warning" %} ~~Rune and~~ Only Runeword effect is unaffected to troops except stats (

) change. {% endhint %} ## Rune Upgrade Runes are divided into several rarity. Runes with higher rarity will have stronger stats To upgrade runes to higher rarity, players need the same amount of runes, sMAG

and MSTR

Ra	3	60,000	25	12,500

## Equip and Remove Runes Mongen can equip up to 6 runes regardless of level or rarity. When the player no longer wants to use runes, the player can use sMAG

to remove the runes from the mongen and return them to the inventory.
