Golden Star
A mechanical dragon with golden coloring and destructive dragon breath, housed within Marni's Masterium in Delesyia.
Marni's Clockwork Mantis
A mechanical praying mantis weapon that fell from a sky galleon's debris during the Frozen Hearted Predator quest in Delesyia's Gorthak region (Chapter 10 — Counterattack: Greater Firepower). Its metal heart rampaged with overwhelming power before freezing over. Despite its intimidating appearance, it is one of the easier bosses in the late game. Its most dangerous attack is the yellow laser beams, which can potentially one-shot at lower HP. Its melee attacks deal relatively low damage.
Thunder Tank
A heavily armored mechanical tank boss encountered while assembling Marni's transporter in Delesyia. Guards one of three fortress keys needed for progression. Its impenetrable armor makes it impossible to kill with normal sword strikes. Features AoE attacks, homing missiles, electric emitters, and a devastating charge attack that can delete your health bar. Requires the Aerial Maneuver skill (from Axiom Force Lv2) to defeat.
