9th Tier
A tier entered only by high-level players and NPCs; under the seven-levels-per-tier theory it corresponds to levels 57–63.
- Signature spell: [Grasp Heart] — an instant-death spell that crushes the heart, inflicting stun even if resisted
- [True Death]: prevents resurrection by low-tier resurrection magic; Ainz killed Gazef with it
- [Vermilion Nova]: the highest single-target fire attack short of super-tier magic; [Call Greater Thunder]: the highest single-target lightning spell
- [Nuclear Blast]: somewhat weak damage, but among the largest areas of effect of any spell, with knockback, poison, blindness and more
- [Perfect Unknowable], [Temporal Stasis], [True Resurrection], [Greater Rejection] and others
- Decem is the first local confirmed to be able to use 9th- and 10th-tier magic
- [Elemental Form]: an upgrade similar to [Aspect of Elemental] (Vol. 16); [Tempest] (Vol. 16); [Crack in the Ground]: divine magic in which a fissure traps the target like a bear trap, with effects such as instant death (side story)
- [Polar Claw]: the highest-damage cold spell, with no added effects; [Mist of Super Acid] (10th tier) deals the most damage to the Platinum Dragon Lord's platinum armor — the Ainz played by Pandora's Actor cannot use either (Vol. 14)
- [Bless of Titania] and [Lead of Yatagarasu]: respectively show a low-danger route and the shortest route straight to the heart of a dungeon (BD bonus novel)
- [Greater Rejection] can only banish summoned beings, not beings produced by creation-type abilities (Vols. 3 and 16)
