Your touch inflicts disease. Make a melee spell attack against a creature within your reach. On a hit, the target takes 5d8 necrotic damage and is poisoned. While poisoned in this way, the creature has disadvantage on disadvantage on saving throws made with the ability of your choice.

The target must repeat the saving throw at the end of each of its turns until it gets three successes or failures. If the target succeeds on three of these saves, the spell ends on the target. If the target fails three of these saves, the target is no longer poisoned, but instead suffers one of the below diseases for the next 7 days.

If the creature receives an effect that would otherwise end the poisoned or diseased condition while still affected by this spell, the creature must succeed on a Constitution saving throw against your spell DC or the condition does not end.
