EO2U/Beast/Skills

This page details full data for the Beast'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 have twice its maximum level.

Force skills

Desperation 捨て身の心
Support Skill: Force Boost Triples HP for 3 turns. Amplifies one's vitality. Also fully restores the user's HP.

True Endurance 究極がまん
Defense Skill: Force Break Shields all attacks/endures this turn. At end of turn, melee bash all enemies. Stand in front of one's allies and endure all incoming attacks. Negates stuns, binds, and ailments. The in-game description claims the skill deals bash damage, though it actually deals stab damage (this is likely an error). Damage dealt scales based on the user's level. The skill redirects all attacks to the user, so damage suffered is calculated using the user's defense values, instead of the original target's. The user cannot die during the turn where this is used, except to instant death. The user also becomes immune to all binds and ailments, except instant death.
