Surge of Adrenaline

A creature you touch regains a number of temporary hit points equal to 4d8 + your spellcasting ability modifier. This spell has no effect on undead or constructs.

When the adrenaline wears off after an hour, the chosen creature will loose the temporary hit points and gain an exhaustion point. If the creature's hit points goes below 1, the creature automatically goes unconsious. However, using a Greater Restoration spell before Surge of Adrenaline is over will cause the creature to half the temporary hit points but keep them and will not be exhausted at all.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the healing increases by 1d8 for each slot level above 4th.
