I was playing around with mirage's 2nd ability and the training bot/spawned enemy seemed to have their max health "erased". First it seemingly deletes the health bar. Then after expiring completely draining the enemy of all health, with this effect persisting to the next life. It also seems to add max life to the mirage which cannot actually be reached (the shop heal doesn't bring me to max)
