A creature requires an amount of water per day based on its size, as shown in the [[#Water Needs per Day]] table. A creature that drinks less than half the required water for a day gains 1 [[Exhaustion]] level at the day's end. **Remove Exhaustion.** [[Exhaustion]] caused by dehydration can't be removed until the creature drinks the full amount of water required for a day. # Water Needs per Day | Size | Water | Size | Water | | ------ | ---------- | ---------- | ----- | | Tiny | 1/4 Gallon | Large | 4 Gallons | | Small | 1 Gallon | Huge | 16 Gallons | | Medium | 1 Gallon | Gargantuan | 64 Gallons |
