'FEEDBACK' / 'NOSEBLEED' Psionicists can use hyperfocus to improve the potency of their spells. However, doing so runs the risk of over-exerting and causing themselves a nosebleed that lowers their maximum health. This feedback effect cannot be cured by healing spells and herbs, instead it can only be recuperated by natural regeneration. The effect of the feedback will become smaller as the psionicist gradually recuperates from it. See also: TICK
