Horn of the Goblin General

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

Description
One of the few consumable in the game that could not be converted into data crystals. By YGGDRASIL standards, the summoned goblins were weak and only used to buy time for the summoner. However since being introduced into the New World, the item is viewed as a major breakthrough in magical summoning as the goblins have become permanent existences and capable of independent thought.

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, which included Hoplites as the core troops, goblin beast riders, goblin paladins on white wolves, goblin longbows, goblin magic support squad, goblin magic artillery squad, goblin medic squad, goblin musician squad, goblin assassination squad, 13 level 43 goblin red cap honor guards and a goblin tactician commander dressed as Zhu Ge Liang.

Trivia

 * Enri Emmot was given two horns by Ainz and has used up both of them.
 * The horn is appraised to be each worth at least several thousand gold coins.
 * The second horn was used in Chapter 3 of Volume 9 by Enri to summon an entire army of Goblins. 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).
