Hallowed Effigy

Wondrous item, rare (requires attunement)

These small totems, crafted from animal bones and the skull of a tiny woodland creature, all bound in thin leather strips, serve as a boon for those loyal to nature and as a stinging trap to those who threaten it.

You can use an action to secure the effigy on any natural organic substrate (such as dirt, mud, grass, and so on). While so planted, it pulses with energy in a 15-foot- radius sphere, and at the beginning of each of your turns, it activates to effect all within range: you and any creature friendly to you regain 1d6 hit points, and any creatures hostile to you must make a DC 15 Constitution saving throw, taking 1d6 necrotic damage on a failed save or half as much damage on a successful one.

This totem has 9 charges. Each round it activates, it uses 1 charge. While planted, it activates automatically each round unless you pick it up, it runs out of charges, or it is destroyed. It regains 1d6 + 3 charges daily at dawn. If it ever runs out of charges, it must be purified once again by a druid of at least 5th level to be reused.
