Attention of Evantine

Your Goddess pays close attention to your targets. As long as concentration lasts, you deal an extra 1d6 radiant damage to the target whenever you hit it with an attack. Also,  the target has disadvantage on ability checks made with one chosen stat.
If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to curse a new creature.
At Higher Levels. When you cast 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.
