List of Summoning Spells and Magic
When a summon spell is already activated by its summoner, casting another summon spell would cause the previous summon spell to end. 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.

Tier Spells

List of Summoners
Summoners are individuals who're capable of conjuring minions from different races. Some of these individuals also happen to be a Magic Caster. Through various means in being able to summon one, the user would ranged 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. Moreover, unless their summoners were specialists, summoned monsters were generally weaker than the ones who called them forth.

With multiple summoners in one group, it is possible for them to conjured monsters as a form of military 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.

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 they were beings that did not die even when they were killed during battle, they could somehow be fully utilized in this kind of fashion.

List of Summoned Monsters
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.

Summoned monsters could be banished in several ways: when their summoning time ended, when they took too much damage, or when their masters manually dismissed them. When a monster was banished from taking too much damage, it was a common tactic to immediately re-summon another monster of the same type.

Trivia

 * Let alone a Super-Tier Spell, there exists a ritual that requires a living sacrifice or more to be carry out for summoning a being like the undead.
 * Although a summoned undead such as the Death Knight can stay active permanently via a dead corpse, it doesn't work the same way with a Super-Tier Spell and requires a living sacrifice rather than having them dead to use as catalyst for summoning these entities.
 * Summoned monsters like the Death Knight for example are capable of causing weaker beings than themselves to appear through the target it killed.
