I would like to see it have a cheaper ability cost, and with a timer (similar to Cloak), and can be used X times per turn. Maybe that doesn't fit as well with what you intended, but I think it would strike a good balance between being OP and UP. It would give life even more "growth", but would also limit a player from simply spamming these out once enough 100 life quanta was accumulated.
My suggested changes aside, I like this due to the fact that it give mono life a soft counter to shields and CC, both, which fits perfectly thematically. Overall, I really like the idea, Morm.
