The Eternal Seal Spell is a sealing spell used by the Holy Knights that is used to trap very powerful individuals.

Description
The Eternal Seal Spell is a trapping and sealing spell, triggered by breaking an Incantation Ball, that has enough strength to contain ten Tyrant Dragons, each of whom had the strength to level an entire town singlehandedly. In the Baste Dungeon, the spell was set and designed to be a last-resort move, in case the Weird Fangs could not stop the Seven Deadly Sins from entering the dungeon. Even still, the spell, and the dungeon, were both easily destroyed by Ban and Meliodas' greeting.
