Sandskimmer

(Sandstorm, page 52, DnD 3.5)

[General]

You are particularly adept at moving over sand.

Benefit

You treat shallow sand as normal terrain and deep sand as shallow sand. Sand crust does not break beneath your feet, allowing you to move atop it as if it were normal terrain.

Special

This feat can be taken twice, allowing a creature to treat all sand as normal terrain. Its effects also stack similarly with other abilities that improve movement over sand. For example, if a bhuka takes Sand skimmer, she treats all sand as normal terrain and never breaks through sand crust by moving across it.
