Bloodshot Eyes

Upon casting this spell and on every subsequent turn you maintain concentration you take 1 damage (bypassing resistance and immunity) as blood slowly pours from your eyes. While the spell is maintained any attack rolls made against you or anyone within 5 feet of you first require a CON save. If they fail the save blood begins to pour from their eyes, causing 1d6 damage (bypassing resistance and immunity) and imposing disadvantage on all attack rolls made until the beginning of their next turn. This effect only works if the attacking creature has eyes, can see, and has blood.

For every spell level above 4th you use, it causes an extra 1d6 points of damage.
