The evolution of a ZENFORM requires that the Protector has enough skill points which are spent to allow the evoluton to occur. ZENFORMS branch their evolution based on their stats, which are attack, defense and and speed meaning each ZENFORM has the protential to become powerful attackers, strong defenders or swift speedsters.
ZENFORMS have five stages of evolution. The Newborn can progress to Child, Adolescent, Adult and finally to the Grand stage.
The Child stage is the second in the evolutionary chain of ZENFORMS. What Child form a Newborn takes relies on its highest Physical Stat. Evolving a ZENFORM to the Child stage costs 1500 SP.
Child stage ZENFORMS evolve into one of four Adolescents depending on their current form and highest physical stat(s) not represented by their form. Evolving a ZENFORM to the Adolescent stage costs 3000 SP.
The Adult stage is dependent on the highest Elemental Stat of the Adolescent. Each Adolescent has four Adult variants.
The method for reaching the Grand stage is largely unknown - only the very best Protectors have discovered it.Yay!
