** The spell "falling down" may be a reference to "ruin" in the Epic Level Book since Shalltear's body way completely disintegration but it may have been due to the the general effect of powerful magic being used.

* The dub of season 1 episode 7 has Ains consider naming the giant hamster he just captured Anime/{{Hamtaro}}.

--> Albedo: "My, my precious!"

--> Demiurge: "For you see, this is probably the outcome Lord Ainz wanted all along."
--> Albedo: "You mean everything that's transpired has done so according to his design?"
* The mechanics of Yggdrasil are heavily based on ''TabletopGame/DungeonsAndDragons'', specifically editions 3.0 and 3.5, and even include material from obscure {{Sourcebook}}s:

* To ''Literature/LordOfTheRings''. Ainz gives Albedo a guild ring originally intended for guild members only. Since Albedo is madly in love with Ainz, her reaction is rather more extreme than normal.

** Even the tactics used by characters in-series mirror those of experienced D&D players. Adventurers carry "alchemical silver" to pour on their weapons for fighting enemies only vulnerable to silver weapons.[[note]]In D&D the pour-on item is called "silversheen" and "alchemical silver" is the material that actual silver weapons are crafted from, but close enough.[[/note]] Ainz has great familiarity with "Scry and Die" tactics and their counters [[note]]A common player tactic in D&D is to use information gathering spells to locate the enemy and then teleport in an overwhelming force to deal with said enemy. This is why Ainz takes so many anti-scrying precautions since this tactic is ''very'' effective[[/note]], and notes that it's almost impossible to defeat a high-level spellcaster unless you have a way to defend against the ''[[http://www.d20srd.org/srd/spells/timeStop.htm Time Stop]]'' spell. Almost everyone in Nazerick is either undead or wears a ''Ring of Sustenance'' to remove the need for sleep.[[note]]This effectively brings Nazarick's maintenance cost to zero and answers one of the oldest FridgeLogic questions in D&D. How a Dungeon's ecology can actually function without some sort of producer like plants bringing in more food into the ecosystem than the occasional adventurer.[[/note]]

--> "Do or Do Not. There is no 'try.'"

* The Great Tomb of Nazarick has the Pleiades being led by Sebas Tian, a butler with intense combat training. Almost as if the author wanted an {{Expy}} of [[Manga/BlackButler Sebastian]]. Given that he was created and named by a player of Yggdrasil, this may be an in-universe reference as well.

* One of the spells in episode 12 of the anime is ''[[Film/{{Sharknado}} Sharks Cyclone]]''.
