Traits

Celestial Calibration. Lio can align or safely disable an astronomical instrument after one minute. Predict the Curve. Allies within 30 feet have advantage on saves against train movement.

Actions

Brass Divider. Melee Weapon Attack: +5 to hit, reach 5 ft.; 4 (1d4 + 2) piercing. Call the Constellation. One ally within 60 feet adds 1d6 to its next Arcana, Investigation, or navigation check.

Tactics and roleplaying

Lio stays behind cover, calls timing, and uses instruments as leverage. He cooperates with any credible rescue and refuses to endanger passengers. Threats make him quietly misalign the lens rather than fight.

Game Master guidance

This entry is complete for table use. Apply the listed defenses, actions, and encounter behavior directly. If the creature is used outside its original adventure, preserve its surrender trigger and primary motivation so a social solution remains as usable as combat.
