Make them alternatively generate quanta of their opposite element, that's a good idea for making Trios.
Could you explain that?
Anyway, here's some other ideas:
-"
: Generate 1 quanta of every element represented on the field. Does not generate
." This would work but it doesn't generate
! Is that even worth it? Might be good for rainbows though.
-"Each turn, generates 1 quanta for any one element represented on the field." Rainbow again, but more pillar-like, and can actually generate
. But doesn't feel particularly special.
-"Heal 1HP for every pillar or pendulum you own at the end of your turn." The original idea, but not very... original. It's defensive, which is apt for Gravity, but I'd prefer quanta generation.
