Tools...like a pickaxe

[Taxorgian]

The number of turns you need to dig is greater than the lifetime of a sand path. So if you try to use your trusty pickaxe to dig through, the sand will collapse on you. This is not fun if you are a skeleton, from the damage you take, but anything else will die from suffocation too. It's a BAD idea in other words.

Though you could just sit, buried in the sand, and rest, no?

If you're not undead, if you stay there your character will get eternal rest....
