Wand of teleportation

A wand of teleportation can teleport away monsters and items. You can even zap it at yourself as a way to teleport.

It's one of the few universally useful items; the only time it doesn't always work is against the three Riders (but even then it has a small chance to succeed). Wands of teleportation work even on notele levels, unless you're trying to teleport yourself.

In high density areas like Moloch's Sanctum and the Astral Plane, wands of teleportation are invaluable.

Wands of teleportation, along with cancellation and make invisible, will make engravings vanish. If you engrave-ID a vanishing wand, you can test if it's teleportation by zapping a monster or item.
