1st Tier

第1位階 · Magic & Power Systems · Magic Tiers

The most common tier, containing many practical spells; under the seven-levels-per-tier theory it corresponds to magic-class levels 1–7.

Signature spell: 〈Magic Arrow〉 — unerring non-elemental bolts of light, more of them the higher one's usable tier; Ainz can fire 10, Ninya two
〈Floating Board〉: creates a semi-transparent floating board for carrying cargo; team Darkness was transported from E-Rantel to the royal capital by flight magic plus floating boards
Everyday and support spells such as 〈Clean〉, 〈Create Water〉, 〈Alarm〉, 〈Sleep〉 and 〈Light Healing〉
The "rabbit magic" trio, such as 〈Rabbit Ears〉, was inexplicably popular in YGGDRASIL, and Narberal knows all three
Another account: anyone can learn it with training, and being able to cast it is enough to make a living (unverified)
Other 1st-tier spells: 〈Sense Enemy〉 (detects nearby enemies), 〈Repair〉 (emergency repair that lowers maximum durability, Web novel), 〈Preservation〉 (keeps things fresh), 〈Appraisal Magic Item〉, 〈Detect Enchant〉 and 〈Compass〉 (side story)
Everyday magic: 〈Create Water〉 can be divided and its temperature adjusted (side story); 〈Destruction Water〉 makes water vanish like an illusion and can also badly damage water elementals; there are also spells that create salt and spices (Web novel)
Summoning: 〈Summon Undead 1st〉 (Satoru Suzuki summons a dog zombie in the side story) and 〈Summon Monster 1st〉 (summons lesser wind and water elementals)
In the Web novel the magic academy's Jiet can cast only up to the 1st tier

Notes

〈Alarm〉 is a local spell not found in YGGDRASIL.
