Blood Tide

When you cast this spell, a creature you designate within range must succeed on a Constitution saving throw or bleed from its nose, eyes, ears, and mouth. This bleeding deals no damage but imposes a -2 penalty on the creature's Intelligence, Charisma, and Wisdom checks.

Blood tide has no effect on undead or constructs.

A bleeding creature might attract the attention of creatures such as stirges, sharks, or giant mosquitoes, depending on the circumstances.

A cure wounds spell stops the bleeding before the duration of blood tide expires, as does a successful DC IO

Wisdom (Medicine) check.

The spell's duration increases to 2 minutes when you reach sth level, to 10 minutes when you reach ith level, and to I hour when you reach 17th level.
