The Hidden Potential System allows you to further strengthen your UR and LR characters by unlocking nodes on a grid. To unlock nodes, you need duplicate copies of the character (or specific 'Elder Kai' units) to open 'paths' (bottom-right, top-left, top-right, bottom-left). Each node provides stat boosts (HP, ATK, DEF) and allows you to choose specific abilities: Critical Hit (chance to deal 2x damage), Additional Attack (chance for an extra normal or Super Attack), and Dodge (chance to completely evade an attack). The optimal distribution of these abilities depends on the character's kit. Generally, Critical Hit and Additional Attack are prioritized for damage dealers, while Dodge can be useful for defensive units. Unlocking all four paths and maxing out the Hidden Potential is known as 'rainbowing' a unit, making them incredibly powerful.
