Peridot of Planar Protection

Wondrous Item (crystal), very rare (requires attunement)

This small crystal necklace anchors your soul and protects you from all extraplanar influences.

Detect Portal

You automatically sense the presence of any portal within 120 feet of you and instinctively know roughly where it leads. With 10 minutes of concentration you can sense whether or not there are portals within 1 mile and what plane they lead to.

Ethereal Step

Once a day, you can use your bonus action to cast Etherealness, though it ends at the end of your current turn.

Cleanse Spirit

You and your allies within 120 feet of you become immune to the emotional effects of the outer planes while you wear this crystal.

Antipathy

Once per day, you can cast Antipathy as an action, targeting Aberrations, Celestials, Elementals, Feys, or Fiends. This version lasts for 1 hour (concentration). The DC is 17.
