History Main / BlowThatHorn

* ''Literature/Overlord2012'' the horn of the goblin general is a low-level single-use magic item that summons a small number of goblins who are loyal to the user. Ainz gives two of them to Enri as a gift since he is so powerful that the horns are a trash item to him. He is shocked when she later is forced to use the second horn and it summons a huge army of highly skilled goblins. Apparently, she accidentally met the conditions to unlock the horn's secret power, which Ainz didn't know the horns had.
