The spirit of Obojima comes to your aid in your times of greatest need. When you are reduced to 0 hit points, you instead regain half of your hit points and are lifted to your feet amidst a turbulent tempest of petals.

You can then immediately use your reaction to send a wave of concussive wind sweeping out from you. Each creature in a 10-foot radius centered on you must succeed on a Strength saving throw against your spell save DC or be pushed 15 feet away from you and suffer 2d8 slashing damage.

You may only benefit from this spells effects once per long rest.
