Tendril Ring

Found by Marnab, Boldrek, and Odrik in Ullen Vale / Nellu Valley.

This ring is made of a dark, rubbery, slightly sticky material. When you put the ring on it feels like a tiny tendril slithers into your brain matter.

When wearing the ring you gain the following benefits:

You have advantage on Unheimisch saves.

You gain 10 temporary hit points when entering the Shadow Place and after a short rest in the Shadow Place.

You have advantage on Intelligence, Wisdom, and Charisma saves.

Once you save successfully, the ring crumbles into bits and falls from your finger, its magic spent.
