Cape of the Mountebank

Wondrous item, rare

This cape smells faintly of brimstone. While wearing it, you can use it to cast Dimension Door as a Magic action. This property can’t be used again until the next dawn.

When you teleport with that spell, you leave behind a cloud of smoke. The space you left is Lightly Obscured by that smoke until the end of your next turn.
