Well of Radiance

Uttering a sacred Vow of Protection, you conjure a radiant sword and drive it into the ground at a point within 5 feet of you. From this point, a pillar of pulsing holy light erupts in a 15-foot-radius Emination. The area within the emination is considered daylight, and it sheds dim light for an additional 10 feet beyond its boundaries.

The effect lasts until the start of your next turn and creates the following benefits:

Allies within the area regain 2d8 hit points and gain resistance to necrotic, radiant, and nonmagical bludgeoning, piercing, and slashing damage.

Attack rolls against those allies are made with disadvantage, and their attack rolls against creatures outside the area are made with advantage.

If an ally within the area is reduced to 0 hit points, they immediately rise with 1 hit point instead.

Creatures within the area have vulnerability to radiant damage and the ground beneath the area is considered difficult terrain.

When cast with a spell slot of 5th level or higher this spell's healing increases by 1d8.
