Bestow Curse
You touch a creature, which must succeed on a Wisdom saving throw or become cursed for the duration. Until the curse ends, the target suffers one of the following effects of your choice:
• Choose one ability. The target has Disadvantage on ability checks and saving throws made with that ability. • The target has Disadvantage on attack rolls against you.
• In combat, the target must succeed on a Wisdom saving throw at the start of each of its turns or be forced to take the Dodge action on that turn.
• If you deal damage to the target with an attack roll or a spell, the target takes an extra 1d8 Necrotic damage.
Using a Higher-Level Spell Slot. If you cast this spell using a level 4 spell slot, you can maintain Concentration on it for up to 10 minutes. If you use a level 5+ spell slot, the spell doesn't require Concentration, and the duration becomes 8 hours (level 5-6 slot) or 24 hours (level 7-8 slot). If you use a level 9 spell slot, the spell lasts until dispelled.
Bestow Curse 5e 2024 vs. 2014 edition differences
The 2024 version specifies "up to 1 minute" duration, clarifies the target "suffers one of the following effects," and changes the combat effect to forcing the Dodge action instead of wasting the target's action. It also adjusts how concentration and duration work with higher-level slots, specifying that 5+ slots don't require concentration, with durations of 8 or 24 hours depending on slot level.
