"What is this?"
"Protection spell. Once I'm done, evil will not be able to cross the line created by the flowing water."
Zed Martin and John Constantine[src]

A protection spell is often used by John Constantine to create safe areas which block the advance of enemy spells or creatures.


The spell is based on painting a physical circle around a target area, which is then enchanted with magic to keep evil powers and creatures like demons out. A version used by Constantine around the barn with the residing Imogen used a turned on water hose running around the building, to create a constant flow of water that is also supposed to keep evil out. The spell can only be dismissed by the caster, and not even angelic beings can dispel it.[1]

The spell's incantation is in Latin, the language of the Roman Empire.


Chas Chandler used a warding spell to cast the Eye of Horus upon Liv Aberdine's door, and later John Constantine created a protective circle to control the movements of Furcifer, luring the demon to his destruction.[2] He used the protective circle technique again while protecting the barn where the angel Imogen resided in. When Imogen turned out to be a fallen angel, the protection spell managed to cage her inside the barn instead of keeping evils out.[1]

John Constantine used the protection spell creating a safe perimeter around the summer camp while working together with the Legends. However, it did not affect the shtriga masquerading as "Chad Stephens".[3]
