How To Learn
Learning the basics of goblinese can be a little slow, but it gets better afterwards. In order to get started you will want to find the business cards that goblins often drop in the goblin dungeon. One of these cards has a requirement of Level 0, which will earn you the skill. Keep reading more cards in order to raise the skill further.
