Armageddon Evil

最終戦争・悪（アーマゲドン・イビル） · Magic & Power Systems · Key Spells & Skills

A 10th-tier spell that summons a mass of demons; individually they are weak, and they run amok on their own.

Its main use exploits the fact that the summoned demons do not count as allies, so they can serve as sacrifices for ritual magic or special skills
During "Gehenna" in Vol. 6, Demiurge summoned demons with an item of the same name left by Ulbert
That item is Ulbert's failed attempt at imitating a World Item; each of its six gems holds one casting of this spell
Per the side story The Vampire Princess of the Lost Country, the spell can summon demons as high as the 60s and 70s in level, but Satoru canceled those two tiers (side story-345)
Tiers summoned in the side story: 64 Lesser Devils (level 10 or below; 128 in another note), 32 Scythe Demons (level 20s; 64), 16 Rot Devils (level 30s; 32), 8 Supplication Demons (level 40s), 4 Chariot Demons (level 50s); the summons of 2 in the level 60s and 1 in the level 70s were canceled
Chariot Demons can buff nearby demon commander types; one charge from Cure Elim dealt them more than half-lethal damage (side story-345)

Notes

The counterpart "Armageddon Good" resembles the super-tier spell [Pantheon].
