Horn of the Goblin General

Horn of the Goblin General is a minor expendable magic item from YGGDRASIL that summons a Goblin Troop of nineteen goblins.

Description
It is one of the few expendable in the game that could not be converted into data crystals. By YGGDRASIL standards, the summoned goblins are weak and only used to buy time for the summoner. However, the item is viewed as a major breakthrough in magical summoning as the goblins have become permanent existences and capable of independent thought. The horn can only be used once; the item disappears after it served its purpose.

Appearance
The item seems to be a simply made horn with a leather strap attached to it.

Abilities
This magic item can summon nineteen goblin summons consisting of twelve lesser goblins, two goblin archers, one goblin mage, one goblin priest, two goblin wolf riders and one goblin leader, each highly skilled and trained warriors with a strong loyalty to their master.

However, if certain conditions are fulfilled, it can summon an army of goblins, about five thousand strong, which includes several goblin corps, such as: goblin hoplites, goblin beast riders, goblin paladins on white wolves, goblin longbow archers, goblin magic support squad, goblin magic artillery squad, goblin medic squad, goblin musician squad, goblin assassination squad and red cap honor guards. There is also a unit called the Goblin Rear Echelon Support Unit. It was populated by individuals with rare vocations. Apart from the Goblin Weather Forecaster, Goblin Strategist dressed as Zhu Ge Liang, Goblin Blacksmith and so on for a total of 12 jobs.

In the Web Novel, monsters summoned from this item can only stay in the New World for about one hour.

Trivia

 * Enri Emmot was given two horns by Ainz and, as of Volume 9, has used up both of them.
 * In the New World, the horn is appraised to be each worth at least several thousand gold coins.
 * It was said that the true power of the horn can only be activated by meeting 3 conditions which were not clarified in the novel.
 * The true magic of the horn was an unknown secret even amongst the YGGDRASIL players who regarded the horn to be trash.
 * Ainz has used the horn before, but never met the conditions like Enri successfully did in summoning an army of five thousand goblins.
 * When a magic caster was inspecting Enri's magic items during her journey to E-Rantel, they identify the Horn of the Goblin General to be very potent, suspecting the girl to have been given one by a priest from the Slane Theocracy.
