So, does it only work within a certain threshold? For example, if the enemy has X% more health than the creature wielding singularity, it simply doesn’t work? Or does it only exchange a certain percentage of health? I’m almost certain that I saw no change, but it was a few hours ago so it’s possible that I may have been mistaken.
Cephyric: As far as balance is concerned, if Singularity caused a switch that multiplied the creature’s health even twentyfold as you suggested, the enemies are at such a high level that their attack has scaled appropriately with their health. Even with a massive amount of health, the friendly creature would still probably die in a couple of hits. Damage reduction would still be a much more formidable source of effective health, and there are more potent solutions currently available (Blood Dance). Balancing Singularity to a percentage would more likely be for the purpose of preventing players from swapping the health of friendly creatures with high level enemies so that those enemies can be eliminated next turn with a single hit.
