What is Ultimate Enhancement?
Add Equipment Slots

Ultimate Enhancement is a training method that adds a weapon or armor slot to a 6-star Hero, and it is unlocked when you obtain a 6-star Hero. To perform an Ultimate Enhancement, you need to consume another 6-star Hero or the Ultimate Enhancement Material, Leah, as a material.
![]() | Leah is a Hero, who is exclusively used as an Ultimate Enhancement Material and cannot be added to a party. |

How to Use Ultimate Enhancement
Select a Hero from Ultimate Enhancement

Go to Home > Power Up > Hero Enhancement > Ultimate Enhancement screen. After selecting the Hero you want to enhance and the material Hero, choose whether to add a weapon or armor slot and consume Gold to perform the Ultimate Enhancement.
Increased Equipment Slots

You can only add a total of two slots with Ultimate Enhancement: one weapon and one armor slot. Be aware that you cannot add Accessory slots.
Benefits of Ultimate Enhancement
Raises Stats with new Equipment

Performing an Ultimate Enhancement increases the number of equipment slots, allowing you to raise various stats by equipping more items. Since you can choose the equipment freely, the benefit is that you can raise the stats you want for that Hero according to your preference.
Use Leah as Material
It is recommended to use 6-star Heroes in battle or as Crafting materials rather than as Ultimate Enhancement Materials. Therefore, you should basically use the exclusive material, Leah, for Ultimate Enhancement.

How to Obtain Materials
1. Event Rewards

Ultimate Enhancement Materials can sometimes be obtained as rewards from mission-type events.
2. Topaz Exchange Shop

In the Topaz Exchange Shop, you can exchange 2500 Topaz for an Ultimate Enhancement Material. Topaz can be obtained by purchasing paid items, and you also get 5 Topaz per Power Up Package that can be bought with Rubies.
