You create an area of protection that shields your allies from harm. The area is a 20 foot radius sphere centered on a point you choose within range, and it glows with soft golden light that produces dim light within. The area has a pool of 30 hit points that any creature you designate when you cast this spell can draw on to restore their health. A chosen creature inside the area can use its reaction to regain hit points from this pool immediately after being dealt damage. A creature can use this reaction even if it would normally be knocked unconscious or killed.

Constructs and undead creatures can’t restore hit points from this spell.
