Designed for the Desert

Dwarf

You're acclimated to desert environments and require very little water to survive, you require only 2 unit of water per day instead of the normal 12 units per day. You're also naturally adapted to hot climates and do not suffer the normal ill-effects of such environments. You can move across and climb sandy surfaces without needing to make an ability check. Additionally, difficult terrain composed of sand doesn’t cost you extra moment.
