Tero's Lighthouse

The light of Tero spills forth from you, comforting those you call friend. You emit bright light in a 15-foot-radius, and no additional light beyond that point. If any of this spell’s area overlaps with an area of darkness created by a spell of 4th level or lower, the spell that created the darkness is dispelled.

When you cast this spell, you can designate any number of creatures you can see as your allies. You and your allies who remain in the area of bright light gain your spellcasting modifier in temporary hit points at the beginning of each of your turns. Creatures attacking you or your allies within the area of bright light must succeed at a Constitution saving throw or suffer disadvantage on their attacks. Creatures who are immune to the blinded condition do not suffer this disadvantage.

If you are immune to detect thoughts, or are in a location that prevents clairvoyance, this spell fails and the spell slot isn’t expended.
