Leveling Up Information

You level up your heroes by using both ISO-8 and Gold. Different rarity heroes require different amount of ISO-8 experience to level up. The amount of XP needed gets higher the higher level hero reaches.

Your catalyst can be substituted as ISO-8 experience as well. However, because they are much more rare and sometimes require special events, you should generally never use catalyst to level up your hero. Below we will list out the amount of EXP needed for each level.

It should be noted that your heroes are capped per every 10 levels, you can rank up to increase the max level. If you need more ISO-8’s to level up your heroes, please check out our ISO-8 farming guide for quests.
