Sickening Radiance

Level: 4th
School: Evocation
Casting Time: 1 action
Range: 120 feet
Components: V, S
Duration: Concentration, up to 10 minutes

Description:

A dim, greenish light spreads within a 30-foot-radius sphere centered on a point you choose within range. The light spreads around corners, and it lasts until the spell ends. When a creature moves into the spell’s area for the first time on a turn or starts its turn there, that creature must succeed on a Constitution saving throw or take 4d10 radiant damage, and it suffers one level of exhaustion and emits a greenish light in a 5-foot radius. This light makes it impossible for the creature to benefit from being invisible.

Notes:

• Damage and Exhaustion: This spell deals substantial radiant damage and inflicts levels of exhaustion, which can severely debilitate creatures over time.
• Invisibility Counter: The greenish light emitted by affected creatures can negate invisibility, making it a tactical choice against sneaky or hidden opponents.
• Area Control: The 30-foot radius and the spell's ability to spread around corners make it effective for controlling large areas or enclosed spaces.
