Hallowed Beast Mask (Patreon)

Wondrous item, uncommon (requires attunement by a druid)

This skeletal mask is ceremonially carved from the skull of an animal. While wearing it, whenever you use your Wild Shape feature to transform into a beast, you can choose to transform into a skeletal version of it. While in this form, you have resistance to poison damage, and your creature type is undead instead of its normal type.

When the effects of your Wild Shape end and you revert to your normal form, you can choose to release a horrifying wail (no action required). Living creatures of your choice that can hear the wail within 15 feet of you when you transform must succeed on a DC 13 Wisdom saving throw or become frightened of you until the end of your next turn. A creature makes the saving throw with disadvantage if you are both within dim light or darkness.

“The veil that separates this world from the next is no less a natural boundary than where land meet sea. And just like any natural boundary, what seems plain and normal on the one side is wildly out of place and unsuited for the other. Think not of the other side as a realm of death, but as a place to rest before beginning the cycle of life anew.”
