Rune Slot Enchant

  • Rune Candor Essence can be used to enchant the slot of a Skill Rune.
  • When Rune Candor Essence is used on a Skill Rune, a random slot is changed into ‘White’.
    • White Rune Slots can be connected to Link Runes all colors.
    • Based on the level of the White Rune Slot, the linked Link Rune’s level is applied at an increased level.
    • If different Skill Runes with White Slots are equipped with a Link Rune in between, the increased level effect of the Link Rune is applied individually to each Skill Rune.. (Skill A White Slot – X Link Rune Lv. 30 – Skill B White Slot > Lv. 31 X Link Rune effect applied to Skill A / Lv. 31 X Link Rune effect applied to Skill B)
  • If multiple essences are used on a slot that has already changed to White, it can be further enchanted. In this case, the Link Rune’s level increases by the number of enchantment stacks.
  • When a Rune Candor Essence is used on a Skill Rune, all other essences besides ‘Rune Link Essence, Rune Birth Essence’ and Rune Upgrade Essences cannot be used.

  • Consecutive successes with Rune Candor Essence decreases the success chance of the next enchant.
  • Candor Essences can no longer be used upon failing. However, there is a chance the enchantment will be ‘maintained,’ to allow one more try.
  • If maintained, instead of the Candor Essence effect being applied, the next enchant’s success chance slightly increases. If the stacks are maintained multiple times in a row, the success chance continues to increase.
  • Successfully enchanting Candor Essence will remove all bonus success chances.
  • Upon completely failing, ‘Rune Color Essences’ can be used on the Skill Rune again. Afterward, Rune Candor Essence can be enchanted again from the beginning.

  • Every 5 successful enchant with Rune Candor Essence increases the Skill Rune’s maximum level limit. (E.g.: 10 Candor Essence enchants on a Skill Rune with maximum level of 30 will allow the Skill Rune to be increased up to Lv. 32)
  • When the maximum level of 30 is surpassed, elements can be used from ‘Rune Growth’ to increase the Rune’s level
  • Rune’s maximum level increase can be applied up to 5 times. The increased maximum level is displayed on the left with a number. Once applied, it does not disappear even when Rune Candor Essence enchant fails and the Rune is reset with ‘Rune Color Essence,’ or ‘Rune Birth Essence.’.
  • If the ‘Previous Maximum Success’ is not surpassed after the reset, the ‘Maximum Level Limit’ does not increase either. E.g.: Maximum Level Limit increased by 2 with 10 Rune Candor Essence successes > Rune Candor Essence enchant fails. Rune is reset and then proceeded to 5 Rune Candor Essence successes. Maximum Level Limit increase is maintained at 2 > Upon reaching 15 Candor Essence successes, the Maximum Level Limit then changes to 3.

Rune Slot Restoration

  • Using ‘Rune Candor Revitalization Essence’ will restore the Rune Slot to its maximum Rune Candor Essence successful enchant count.
    • Can be used on Skill Runes that have been reset with Rune Color Essence after failing Rune Candor Essence.
    • If a Candor Essence enchant attempt fails during a re-attempt, it can be used to restore to the previous highest enchant count without resetting.
  • The maximum enchant record of a Skill Rune enchanted with Rune Candor Essence can be viewed from the Mystic’s ‘Rune Enchant’ UI.
  • If “Rune Birth Essence” is used on a Skill Rune enchanted with Rune Candor Essence, the maximum enchant record is erased. Please be aware that in this case, it cannot be recovered even with Rune Candor Revitalization Essence.
