Spider scuttle

Sometimes known as spiderwalk or spider climb, Spider scuttle is an invocation used by some warlocks, particularly those of the dark pact. When cast, spider scuttle, allows its caster to walk along the walls of a cavern like a spider, giving them shadowy legs that allow them to move with unnatural ease and speed. Spider scuttle is a somewhat complex spell, but warlocks require only a short rest between castings in order to regain the power necessary to cast it.

Prior to the Spellplague, spider scuttle was more commonly known as spider climb, and was usable by wizards and sorcerers as well as warlocks. For the former two, spider climb was like any other spell, the number of castings allowed dependent upon a degree of preparation by the wizard or power of the sorcerer. Druids also used a similar evocation.
