EO2U/Fafnir/Skills

This page details full data for the Fafnir's skills in Etrian Odyssey 2 Untold: The Fafnir Knight. In addition to these skills, each character can equip Grimoire Stones which allow them to use skills from another class or monster. When a character equips a grimoire with a skill they have already learned, the level of the skill and the level of the grimoire are added together, meaning that a skill can go up to twice its maximum level.
