Actions
Blood Quench: 1d10+Con+PB

You must drink from a living Humanoid at least once every day before dawn, or gain one level of exhaustion.

When a humanoid is in melee range you may make an attack roll at advantage in an attempt to bite into their neck and drink their blood. If the creature is restrained, unconscious, or anything other effect that would cause it to be unable to take an action, you automatically hit.

In order to satisfy your Vampiric Thirst, you must drink 5hp plus your player level per day. When you do this, you also recover the same amount of HP.

If this attack downs or kills the target, the HP recovered is doubled.

Sunlight Hypersensitivity:
When you are in the sunlight, you lose Blood Quench's HP Restoration ability. This condition lasts for one hour after you exit sunlight.
