This rule adds a bit of consequence to taking damage (either via combat or spell casting).

• When a character is reduced to 3/4 of their maximum Hit Points (rounded up) he/she is Fatigued.
• When a character is reduce to 1/2 or fewer of their maximum Hit Points (rounded up) he/she is Exhausted.

Unlike normal Fatigued and Exhausted conditions, these conditions are only removed when the character is healed above the applicable Hit Point threshold. Normal rules for stacking Fatigue apply.

Example
A character reduced to “Fatigued” by damage who later suffers another level of Fatigue through physical exertion is thus Exhausted. The Exhausted condition is removed with normal rest, however the Fatigued condition remains until the character is healed above 3/4 of his/her maximum Hit Points.
