Elemental Gacha

Elemental Gacha (ガチャえれ) is a magic item that originated from YGGDRASIL.

Description
An item that was in the possession of Ainz Ooal Gown who rather than keep it in the Treasury, kept it in his Item Box to hopefully give it to someone whose levels were low.

Appearance
It was a Top Class magic item. It is a transparent, glass-like sphere and inside of it were four lights moving around in circles.

Abilities
It is a magic item specialized in summoning Elemental summons of fire, water, air, and earth. In addition to that it can also summon composite Elementals that are a mixture of 2 different elements together such as that of of fire + earth = magma, water + wind = blizzard, earth + water = bog, fire + water = hydrothermal, earth + wind = sandstorm, fire + wind = firenado, and more.

Among these, the elementals of fire, water, air, and earth could manifest as high-ranking elementals with levels in the low-40s, mid-rank elementals with levels in the mid-20s, and as lower-rank elementals with levels in the single digits

In regards to the composite elementals, they could manifest as high-ranking elementals with levels in the mid-50s, mid-rank elementals with levels in the low-30s, and as lower-rank elementals with levels in the low-10s. However, the number of composite elementals summoned in all cases was one.

A single high-ranking elemental can be summoned. The number of mid-rank elementals was random but between 1 and 3 were summoned, the number of lower-rank elementals summoned was also random, but a minimum of 3 to a maximum of 6 were summoned.

Drawbacks
Just from hearing this, you might think it sounded pretty useful, but unfortunately the elemental summoned was chosen randomly. Moreover, compared to the lower-rank elementals, getting a high-ranking elemental to appear was difficult. When it came to the higher-ranking elementals it was on the same level as winning a Shooting Star ring.

It was far too strategically useless to not be able to summon something that suited the opponent or situation. If you summoned an earth elemental when flying in the sky, all you could do was watch it drop like a rock.

Trivia

 * Ainz had used this item to summon an air elemental during his travels to the Great Forest of Evasha.
 * The item had to be used three times until Mare could summon an air elemental.
 * During his fight against Antilene Heran Fouche, Mare summoned one mid level Earth Elemental and much later another stronger Earth Elemental using this item. Shocking and confusing Antilene and causing her to theorize that Mare was somehow blood related to the Elf King and thinking that the elementals he summoned were the legendary Behemot used by the Elf King.
