One of the things I've noticed was whenever I've attempted to use its powers it would briefly start up and then cease immediately afterward. As if all of its powers were drained in an instant. The amount of mana necessary to summon Origin is far greater than that of, let's say Sylph, not to forget the length of time needed to build said mana and actually make the command. That's plenty of time for them to notice and stop it on the spot. Hence another reason why I've been able to summon the other spirits but not him per se. Well, of course, this is all just a theory.

What are some of the spells that haven't worked for you?
