Stress & Sanity

Stress Pool

(Sanity Mod+Con Mod)[minimum of 1]+Proficiency Bonus=Stress Pool
Events that induce stress are over 24 hours without rest, seeing an important ally fall in battle, over 24 hours without proper food/water, being poisoned, being diseased.
A failed Sanity save might result in short-term, long-term, or indefinite madness, as described in chapter 8, "Running the Game." Any time a character suffers from long-term or indefinite madness, the character’s Sanity is reduced by 1. A greater restoration spell can restore Sanity lost in this way, and a character can increase his or her Sanity through level advancement.

Exhaustion with Madness Levels

1. Disadvantage on ability checks
2. Speed halved
3. Disadvantage on attack and saving rolls
4. Short term madness (on a Failed DC10 Sanity Save)
5. Long term madness (On a Failed DC15 Sanity Save)
6. Hit point max halved
7. Indefinite Madness (On a Failed DC20 Sanity Save)
8. Speed reduced to 0
9. Death

You can restore your stress pool by 1d4 per short rest and 2d4 per long rest. During your rests you have to do something that decreases stress.
ie Just taking hit dice on a short rest to restore health wont restore stress. iee. However Sitting down having a meal, playing a tune, warming up by a fire would Restore Stress per (short/long)
ie: Environment: Roughing it without proper shelter can cause stress to the pool even though you are resting.
After your Stress Pool is depleted you start incurring Exhaustion up to level 3 if you do nothing to recover stress.
