Ah if it produces 2 quanta per turn that is a different manner.
That does kinda limit its balancing variables.
Obviously although this looks like it costs
in reality it costs trio/quad quanta.
This means the cost is at least equivalent to 2 elemental quanta if not 3.
In return it acts like 2 cards instead of 1.
I think the unupped is balanced. The upgraded can be balanced by mirroring pillars|towers and removing the current upgrade bonus.
This works as nice quanta acceleration and trio/quad quanta fixation.
Chance of producing two types of quanta 67%/75% (I miscalculated before.)
