Baeloth's Cause for Celebration

You place a curse on a creature that you can see within range.

If the target drops to 0 hit points before this spell ends, it explodes into magical paper confetti in a 5-foot-radius sphere centered on the target. Each creature in the area must make a Constitution saving throw. A creature takes 1d6 thunder damage and its speed is reduced by 10 feet until the start of your next turn on a failed saving throw, or half as much damage on a successful one. If a creature drops to 0 hit points due to the explosion, it explodes in the same way, starting a chain reaction.

When this spell ends, you can use a bonus action on a subsequent turn of yours to curse a new target.

A remove curse [Tooltip Not Found] on the target ends this spell early.

At Higher Levels. When you [Tooltip Not Found] this spell using a spell slot of 3rd or 4th level, you can maintain your concentration on the spell for up to 8 hours. When you use a spell slot of 5th level or higher, you can maintain your concentration on the spell for up to 24 hours.
