Power limitations:
Gods:
-Olympians, can keep all the powers they have(To a slightly weaker extent). However they can be killed, if a series enough wound is inflicted they will die or if a series of smaller wounds are inflicted they will run out of the energy needed to heal
-other gods, can keep all the powers they have except for immortality(ie healing) however they will continue to live forever until a wound is inflicted (bullet to the heart, stabbed and bled to death,ext)
Demigods:
-Demigods can have multiple powers as long as they are powers the god/goddess parent had. (Ie: the child of Hades couldn't control water or the weather)
-Demigods can NOT have immortality, they will age and can die of normal means
Monsters:
-canon monsters(Medusa,minotaur,ext), can keep all the powers they have.
-Custom monsters, can have up to 4 powers
