From DragonMineZ Wiki
Every form drains a resource (usually Ki) while it is active. If you can't pay the drain, the form and any stack form are switched off and you return to base. Raise the form's mastery (it lowers the drain), power down (the drain scales with your Power Release) or invest in Energy for a bigger Ki pool. See Transformations and Training Points and Mastery.
