Fatigue accumulates during combat in the Resheph, Flurry, and Katahzirui forms. Once you reach maximum fatigue your combat abilities decline precipitously and death will surely follow.

There are several active ways to manage fatigue:

• Setting nervature to 'nervature fat' will periodically reduce your fatigue level.
• Imbibing ingredients is a powerful way to reduce fatigue. Semuta is particularly good at this.
• Applying wraps soaked in an ingredient will also reduce fatigue.

Many guild skills either reduce the rate at which fatigue accumulates, or increase the rate at which it naturally decreases. Examples of such skills are endurance and finesse.
