Blood Curse

Description:
You conjure ethereal, blood-red scales that float around a target creature, warping its form and distorting its senses. These scales impose a curse on the target, hindering its abilities and defenses.

Effect:
Choose one creature you can see within range. The target must make a Constitution saving throw. On a failed save, the creature suffers the following effects for the duration:

• The target has disadvantage on attack rolls.
• The target cannot take damage from any source until the start of its next turn. However, once it does take damage, it also takes an additional 1d4 necrotic damage.

The target can repeat the saving throw at the end of each of its turns, ending the effect on a success.

At Higher Levels:
When you cast this spell using a spell slot of 2nd level or higher, the additional necrotic damage increases by 1d4 for each slot level above 1st.
