A storm cloud appears in the shape of a cylinder that is 10 feet tall with a 60-foot radius, centred on a point you can see 100 feet directly above you. The spell fails if you can't see a point in the air where the storm cloud could appear (for example, if you are in a room that can't accommodate the cloud).
When you cast the spell, choose a point you can see within range. A bolt of lightning flashes down from the cloud to that point. Each creature within 5 feet of that point must make a Dexterity saving throw. A creature takes 3d10 lightning damage on a failed save, or half as much damage on a successful one. On each of your turns until the spell ends, you can use your action to call down lightning in this way again, targeting the same point or a different one. If you are outdoors in stormy conditions when you cast this spell, the spell gives you control over the existing storm instead of creating a new one. Under such conditions, the spell's damage increases by 1d10.
At Higher Levels: When you cast this spell using a spell slot of 4th level or higher level, the damage increases by 1d10 for each slot level above 3rd.
A remove curse spell ends this effect. At the DM's option, you may choose an alternative curse effect, but it should be no more powerful than those described above. The DM has final say on such a curse's effect.
At Higher Levels: If you cast this spell using a spell slot of 4th level or higher, the duration is concentration, up to 10 minutes. If you use a spell slot of 5th level or higher, the duration is 8 hours. If you use a spell slot of 7th level or higher, the duration is 24 hours. If you use a 9th level spell slot, the spell lasts until it is dispelled. Using a spell slot of 5th level or higher grants a duration that doesn't require concentration.
You touch a creature, and that creature must succeed on a Wisdom saving throw or become cursed for the duration of the spell. When you cast this spell, choose the nature of the curse from the following options.
• Choose one ability score. While cursed, the target has disadvantage on ability checks and saving throws made with that ability score.
• While cursed, the target has disadvantage on attack rolls against you.
• While cursed, the target must make a Wisdom saving throw at the start of each of its turns. If it fails, it wastes its action that turn doing nothing.
• While the target is cursed, your attacks and spells deal an extra 1d8 necrotic damage to the target.
For the duration, a willing target's body parts (fingers, legs, tail, and even its head) can be harmlessly severed from its body. It takes no damage from such dismemberment, as long as the cut removing the body part is swift and leaves a clean cut. The target's head remains alive and conscious, and parts connected to it also remain alive. All severed body parts become inanimate, but do not begin decomposition for the spell's duration. Any of the target's severed body parts that are removed during this spell's duration can be held back to the stump, which instantly causes the part to knit to the stump, restoring the body part.
At the end of the duration, severed body parts become permanently severed. The target dies if vital organs have not been reattached to its head.
