Elite Workshop Day 2 — Let's make something for jumping between Planes!

Hey heroes! Thanks for the votes and comments yesterday! Let's make another item together!

These are loose item ideas based on the suggestions from yesterday's direction poll. Some of these may have had their ideas adjusted or combined with other like-minded suggestions. The final product may or may not use the original wording, so these are the core of the items' functionality and flavor.

Ideas

Aetheric Tether — A worn compass that always points to a set location on a particular plane of existence. You can use it to cast the plane shift spell once, arriving at the set location, but the compass magically vanishes and reappears somewhere on another plane when you do.

Portable Pocket Pitcher — A tent stake that, when driven into the ground, creates a tent that duplicates the effect of the tiny hut spell, with the exception that it fills a cube, and an alarm spell magically encircles the tent.

The Fiend's Pipe — A crooked smoking pipe that smells of brimstone and sulfur when smoked. While smoking it, you can cast the detect thoughts or disguise self spells at will, provided that the tobacco used in the pipe is of a certain gp value. When the spells are cast, you have a cumulative percentile chance of poisoning yourself.

Warp Anchor — A magical rod that snaps in two, creating an invisible tether between each half. While holding a half, you can use an action to cast the teleport spell to appear in a space adjacent to the other half, even if it goes between planes of existence. Each time you do, there's a percent chance that the rod can't be used again, and stays snapped in half.

Thanks for the suggestions! Let's make something fun!
