Leon and the Mech share the exact same abilities, as such, the following description applies to both bosses. The boss will only use three abilities during this battle: Aerial Cruiser, Field Inducer, and Plasma Shower. Aerial Cruiser and Field Inducer aren't very threatening on their own, and the boss will chain copies of these attacks throughout the battle. The two attacks will eat away at the party's HP, though armor with Life Protection will keep the party safe from any real damage.
