Potion of Heroism
Property [Consumable]: As an action, you drink the potion. You gain 10 temporary hit points. These hit points can cause you to exceed your hit point maximum, and they cannot be regained. If you take any damage, these hit points are lost first. In addition, you gain a +2 bonus to ability checks, attack rolls, and saving throws. Finally, the saving throw DC of any spell you cast or magic item you use, or that results from something else you do by increases by 2. The effects wear off after 1 hour.
This colorless potion steams as if boiling. Sampling or drinking it causes the imbiber to feel immensely healthy and robust.
