Inquisitor's Brand

2nd-level evocation (Solarmancy)
Casting Time: 1 action
Range: 30 feet
Components: S, M (An Uncommon or rarer Sunstone)
Duration: 10 minutes

You reach out and cause a searing, radiant brand to form on a target within range that you can see. The target must succeed on a Constitution saving throw or a visible brand appears on their forehead for the duration. While this brand persists, the target takes 2d6 radiant damage each time they take the attack action, each time they target a creature with a harmful effect, each time they force a creature to make a saving throw, or when they willingly speak a lie. This spell ends if they are dealt damage or targeted with a harmful spell by yourself or one of your allies.

If you target a creature in Direct Sunlight, they have disadvantage on their Constitution saving throw made to resist this spell.

At higher levels: When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature within range per spell level above 2nd.
