Sometimes when i fight bosses that are the same as my school i will load a buntch of prisms in my deck.
Sometimes when i fight balance bosses, they boost my attack.
But why is there any balance prism?
Prisms are made to switch out the school that the spell originally is in and into the opposite school, allowing it to boost. All of the other schools have been used, and also, Balance has no opposite. Thus, there is no Balance Prism. Sorry for your, um, loss?
Spectral blast, hydra, and chimera, especially chimera, were all made to replace the issue of balance's prism problem,but i can see why balance might want a prism, we all love our AOE spells.
