Armageddon Evil does work as a mass summoning spell but the summons are particularly weak to begin with and they are mostly used as sacrifice summons to be used in conjunction with other spells; like life banks for Shalltear's Spuit lance or probably even the sacrifice for Ainz to cast Iä Shub-Niggurath. The other downside for the spell is that the demons brought into being don't follow orders and would even attack the summoner. Even if the spell itself is a Rank 10, it's a literally suicide nuke for anyone in the New World who's dumb enough to try it.

I read through the part again, it's the prototype that got turned in. In a way, it's trash disposal. Since Ulbert had been wanting to get rid of the thing in the first place, Ainz simply though it was the right moment back then.
