Tumbling dodge
From BatWiki
Skill duration: 2. Type of skill : special skill. Affecting stats: Dex. It uses 15 endurance points. The truly dextrous often at least try the art of gymnastics or tumbling as a child. This skill is based on the same overall ideas for a much more pragmatic purpose -- evading blows in combat. By leaping, flipping, and rolling around, the user makes himself a lot harder to strike in battle, in exchange for all melee attacks they would normally make themselves. High dexterity is crucial for this skill!
