Summoner

Summoner is the generic term used to refer to a general class of magic casters that exist in YGGDRASIL and the New World in the Overlord series. Besides being a job class name for some, individuals not belonging to the class can still be classified as one to some degree by summoning a monster of their own from other means elsewhere.

* Breath of Fly: It allows Entoma to shoot forth a swarm of small flies. These flies then lay eggs in their victims. The maggots quickly hatch and eat the victim's flesh and rapidly grow to flies, only to repeat the process with new victims. This ability can only be used 3 times per day.
* Undead Lieutenant: If Ainz uses use his experience points, he can even create another level 90 monsters such as Overlord Wiseman, or Grim Reaper Thanatos.
* Unnamed Skill: It allows Ainz to create upper-tier undead four times a day. However, if he divided those up into two uses, he could make undead of roughly level 90. For starters, this special skill allows him to summon either the thief-type Eternal Deaths or sensory-focused Eyeball types under his command.
* Unnamed Skill: With her special skill, Shalltear can turn a low-level undead she created into a lesser Vampire.

When a summon spell is already activated by its summoner, casting another similar spell like it would cause the previous summon spell to end abruptly. The currently-summoned monsters would go back from whence they came and new monsters would be summoned in their place. It is even possible for a summoner like Ainz to conjure forth monsters with a Super-Tier Spell.Overlord Volume 10 Chapter 1: The Sorcerer Kingdom of Ainz Ooal Gown
Besides requiring mana, summoning spells can call forth monsters with different costs. For instance, the function of a Super-Tier Spell, Iä Shub-Niggurath is needed with a lot of people alive as sacrificial pawns in order to summon the Dark Youngs. Whereas there are racial abilities or tier spells which allow the summoning of monsters weaker than that to appear without such a heavy cost of lives necessary. Another application to conjuring monsters is also done through the use of currency, special itemsOverlord Volume 07 Prologue, rituals, summoning systemOverlord Volume 04 Prologue, and so on.
A non-human summoner who specialized in summoning undead can also make use of their racial ability in tangent with dead bodies, serving to be a catalyst for a summoned monster. This includes not only Ainz making the undead permanent but as well as for performing rituals to develop one's undead creation skills. The strength of an undead created by Ainz is variable dependent on the quality of the dead corpses being used or else in an area filled with undead gathered together that is capable of spawning a stronger one.
As a human necromancer, Khajiit utilizes an unknown ritual in the New World which requires sacrificing a city. It was the kind of sacrifices that needed people living in the city as a gateway for spawning undead endlessly. In other words, a city of living could later become a city of undead if this ritual is conducted successfully.

== List of Summoners ==
Summoners are individuals who are capable of conjuring minions from different races. Some of these individuals also happen to be a Magic Caster with a degree of magic or specialization over it such as Ainz, a necromancer. Through various means of being able to summon one, the user would range from one's racial levels, class levels, abilities, skills, tier spells, to items.
If summoners in the New World possessed a Talent related to summoning, it can give them the advantage of strengthening their summoned monsters by a slight margin, etc. Unless their summoners were specialists, summoned monsters were generally weaker than the ones who called them forth.Overlord Volume 02 Chapter 1: The Two Adventurers
With multiple summoners in one group, it is possible for them to conjure enough monsters to form a military-type army. After their previous summoned entities were killed in battle, they can still continue conjuring more of them one after another continuously as long as they have enough mana provided to do so. By doing this, the group of summoners can overwhelm their foes with numbers no matter how weak the summoned entities may be to the opposition.Overlord Volume 01 Chapter 4: Confrontation
In other words, even if the summoned entities vanish, the summoner can keep on summoning more of them from behind to fill the gap. While so, these newly-summoned entities will continue attacking in place of the absent summoned entities. Since summoned entities were beings that did not die even when they are killed during a battle, they could somehow be fully utilized by summoners in this kind of fashion.Overlord Volume 12 Chapter 1: The Demon Emperor Jaldabaoth

== List of Summoned Monsters ==
Summoned monsters were granted a portion of their summoners’ thoughts and knowledge, so they could immediately take action according to their master’s will right after being summoned. Though a mental link connected with its masterOverlord Volume 02 Chapter 4: Twin Swords of Slashing Death, they receive orders and transmit thoughts even without the usage of the 'Message' spell. 
While summoned monsters shared a certain degree of knowledge with their summoners, said information was quite random and disorganized. It would be best to regard it as the ability to tell friend from foe. Therefore, it was important to give verbal commands to summoned creatures. Though summoners could give these orders without speaking and it was possible to give orders to summoned monsters even if spells like [Silence] were used.
According to the author Maruyama, it can be said that the monster's loyalty to its summoner is unbiased and will not change. The reason behind that was due to a kind of empathy being born, like a copy of their summoner's memory. One's right hand does not fight with their brain, and because they shared the same exact empathy as their summoner, there is almost no way to treat a summoned monster badly. There are exceptions though like those who are into hurting themselves.ARCADIA 2.19: ARCADIA 980 10-31-2010
If a summoned monster had received orders from their summoner, they could act swiftly. But without orders, their actions would be slow and conflicted. For that reason, if only the summoned monsters were more intelligent, they could take unusual actions in response to setbacks.Overlord Volume 01 Chapter 3: Battle of Carne Village
If someone wanted to interfere with the connection between the summoner and the summoned, the extremely niche class-build known as the Anti-Summoner Specialist would be needed.
Additionally, there are monsters that required the user to invest a various amount of levels in a certain class in order to meet the qualification for it to be summoned. Under the YGGDRASIL standard, flying dragons could be summoned by those with the cavalry job who had reached the late thirties levels.
Summoned monsters could be banished in several ways: when their summoning time endedOverlord Volume 02 Chapter 3: Wise King of the Forest, when they took too much damage, or when their masters manually dismissed them. When a monster is banished from taking too much damage, it was a common tactic to immediately re-summon another monster of the same type.Overlord Blu-ray 01 Special The Emissary of the King
Further, they can be neutralized by foes with dispel magics such as Greater Rejection, the kind that is able to stop the summoner from summoning more.Overlord Volume 01 Chapter 5: Ruler of Death
It was even said that the Baharuth Empire had initial plans of calling forth summoned monsters for the sake of additional manpower and labor.Overlord Volume 07 Chapter 2: Butterfly Entangled in a Spider's Web
Despite their advantages, a summoned monster’s role was to attack an enemy’s weak point, trigger traps, increase the number of available moves, or to simply serve as a shield. They were not meant to defeat other Players on their own. No matter how unfavorable a comparison it was in terms of battle strength, so long as they were neither greatly mismatched nor some absurd build, one-on-one the Player would rarely lose. 
In YGGDRASIL, players had a limit of how many summons and created monsters they could control. In most cases it was customary for summons to be freed in order from oldest to newest. In the game, there were few examples of a warning message popping up and being able to select which one to release yourself.
Summons could be strengthened by giving them food that granted buffs, though depending on the situation, some players would find it pointless as the summons' existence are temporary.Overlord Volume 15 Chapter 2: Chapter 2: The Travelling Scenery in Nazarick

== List of Summoned Mounts ==
Besides Summoned Monsters, the Summoner is also able to summon their own mount in which they can ride on through their skill or with a magic item. If someone other than the summoner attempt to ride their mount by force, it will unsummon in response. Mount-class monsters called forth by their Summoner could be equipped with various magical items such as armors and horseshoes. The mount can switch between different equipment even if it was summoned with a skill. In addition to that, it is possible to strengthen the summoner's mount with rider-type skills or other abilities like Albedo's.Overlord Volume 08 Side Story 2: A Day in Nazarick
* Golem
* Bicorn
== Trivia ==
* Let alone a Super-Tier Spell-like Iä Shub-Niggurath, there exists a special ritual that also requires a living sacrifice or more to be carried out for summoning a monster.
* Although a summoned undead such as the Death Knight can stay active without duration via a dead corpse, it doesn't work the same way with a Super-Tier Spell. The summoned monsters created from the usage of a super-tier spell stays in the world for a limited duration temporarily and are not permanent.Overlord Volume 09 Chapter 4: Massacre
* Summoned monsters like the Death Knight have abilities for example that are capable of causing weaker beings than themselves to manifest through the target they killed.Overlord Volume 11 Chapter 5: Frost Dragon Lord
* Ainz and Enri are the only two individuals to keep their summoned monsters around permanently while other summoners in the New World can't keep theirs around for long. Unlike the summoned undead or goblins who were shown to have the potential to stay in this world permanently after being summoned, other summoned monsters, for now, haven't been able to do the same. Although the summoned monsters' presence is temporary, Ainz's summoned undead, in particular, had that problem solved with the use of dead bodies or body partsOverlord Volume 01 Epilogue while as summoned goblins are kept around until they were killed because of the item, "Horn of the Goblin General" used by Enri.
* It's quite possible for the summoner to even kill their own summoned monsters such as the case with Shalltear Bloodfallen did to her minions, Albeit this was only made possible due to being transported to the New World, Where in YGGDRASIL friendly fire was not-prohibited.Overlord Volume 03 Chapter 5: PVN
* An interesting note about summoned monsters, particularly those that can use independent magic, is that they are unable to use summoning magic.Overlord Volume 13 Chapter 5: Ainz Dies
* When summoned beings are killed, their physical bodies vanish from the spot.Overlord Volume 16 Chapter 5: Kill Steal
