You touch a closed door, window, chest, or other entryway, and it becomes magically sealed. The caster must designate four locations (two on each side of the seal) where equal blood payment can be provided to break the seal. These two locations will give off ancient magical abjuration energy and are hidden with a DC of your proficiency bonus plus your spell casting ability modifier. The seal is impassable until the spell is paid in blood. Any blood can be used to break the seal (humanoid, fey, monstrosity, etc.), however hybrid and beast forms, disguise self, polymorph, or wild shape spells will still recognize only one entity.
While affected by this spell, the object is more difficult to break or force open; the DC to break it or pick any locks on it increases by 20.
