Modding

Hello. Could you please tell me where the parameter is located that controls whether summoned elementals disappear when summoned again? In other words, is there a way to summon a potentially infinite number of elemental stacks? And if not, where is the "Elemental Equilibrium" ability located in the files? I want to try to make it so that elements summoned by the ability don't disappear. At least, they don't disappear if a mage casts it on another mage with the same ability.
