Talk:Horn of the Goblin General/@comment-209.141.158.177-20150905025145

The 2nd horn was used in Volume 9 which summoned an entire army of goblins. In the novel I read it says in order to activate the horn's power to its greatest extend 3 conditions must be met. However it didn't state what those conditions are( it might be the translation issue). Does anyone know about the 3 conditions by chance?
