Amulet of Planeswalking

While wearing this amulet the attuned creature can breathe normally in any environment, and they have advantage on saving throws made against harmful gases and vapors (such as cloudkill and stinking cloud effects, inhaled poisons, and the breath weapons of some dragons). They can also walk on water, lava, snow, and other diffcult terrain as if it were normal solid ground (ignoring any damage that would be taken from normally traversing such a surface).

In addition, they are unaffected by extreme environmental temperatures and can cast plane shift targeting themselves only once per day, but only to travel back to their own home plane of existence.
