Eternal Coffin (エターナルコフィン Etānaru Kofin) is a freezing spell cast by Chrono Harlaown at the end of A's and its movie adaptation. It is a spell set/recorded by Durandal,[1] although Chrono has also learned it on his own.[2]

In the primary continuity, it is a wide-area attack by generating extremely low temperature in an area to fully freeze the target instead of killing it. Originally a high-level spell of Over-S class (which restricts its usage to all but most powerful mages), Chrono manages to cast it fully thanks to Durandal's optimised tuning for freezing spells, as well as his own learning and training on temperature change and mana conversion.[1] Notably, the spell is originally intended to be cast upon Hayate Yagami after the Wolkenritter complete the Book of Darkness, thus freezing all of them in stasis for all eternity and ending the Book's cycle of reincarnation.

In the movie continuity, it is instead a radiate freezing bombardment. The matters in the effective area can be frozen at maximum efficiency with Durandal's floating sub-units reflecting the overflowing freezing mana.[2]
