has anyone found any real use for armageddon

[Metathron]

I used the spell for half my mage game last time. Mostly because I had found the crown of chaos and a ghost armor that brought my immunity to astral to 70%. My army consisted of black dragons most of the time, those 1000 hp are real important when facing armageddon. I couldn't keep casting it after my intellect grew past a certain point, but this was a really fun tactic to use.
