A skill ball is a function that only characters of UR or higher can be used for each character as well as their potential. By equipping skill balls, you can improve the status and raise the potential skill Lv.
A skill ball is an extension of the potential skill, and each skill ball increases HP, ATK, and DEF. There are also skill balls with potential skills such as continuous attack and critical.
There are three frames for equipping skill balls: copper frame, silver frame, and gold frame. Certain conditions must be met in order to open each slot.
Skill ball (copper frame) release condition The skill ball (copper frame) is released by awakening to the UR .
Skill ball (silver frame) release condition The skill ball (silver frame) is released by setting each character's Special Move Lv to 10 .
A skill ball has the concept of attributes and rarity. The higher the rarity, the higher the effect. Details about the attributes are unknown.
Either the skill ball with the same attribute as the skill ball can only be worn, or the effect is higher if the character and skill ball have the same attribute.
Skill ball (gold frame) release condition The skill ball (gold frame) will be released by releasing the second potential additional route of each character .
Skill balls can be obtained at various events. According to the information on the V Jump, a "training event with Whis" will be held and available there.
