Regalia Type-F

Enter Formouth Garrison under the cover (press the cover button to crouch behind walls or objects) of darkness. Instead of stealth, intentionally get spotted by a guard to trigger a large enemy response, including two level 46 MA Veles Bis mechs.

Prioritize destroying the MA Veles Bis mechs. Use warp-strikes on their legs to ground them, then target their missile launchers on their backs to reduce their threat and deal damage.

Engage the remaining level 18 Magitek Swordsmen and level 3 Imperial Riflemen. Be mindful of their damage output, especially if your character level is low.

After clearing the initial wave, Loqi and Caligo will deploy reinforcements via dropships. The first wave includes level 47 Magitek Assassins, which are a significant threat due to their close-range flurry attacks. Bait out their attacks before going on the offensive.

The second wave consists of a level 45 MA Hoplomachus and another level 46 Veles Bis. Target their missile launchers if they are still active.

The third and final wave comprises Imperial Troopers, Battery Soldiers, and Imperial Snipers. These can typically be defeated with a single warp-strike.

Prepare for the boss battle against Loqi and Caligo, who pilot the level 51 MA-X Cuirass and MA-X Dux mechs. Both have 108,500 HP and share weaknesses to shields and machinery, while being strong against holy attacks.

Focus on destroying the rocket launchers on their backs first. This will make them vulnerable.

The MA-X Cuirass has a shield-like arm that deploys an electric area-of-effect attack and a chainsaw arm. The MA-X Dux fires small missiles that rain down around it. Use hit-and-run tactics to avoid lingering damage.

Targeting the legs of the mechs will cause them to break, leaving them vulnerable. Breaking parts like the rocket launchers also creates openings.

After defeating Loqi and Caligo, you will receive the key item, Strange Engine.

After clearing Formouth Garrison, you will receive EXP 9,000 and the Strange Engine.

Explore Formouth Garrison for additional items. Head north-east from the central section to find two MT Veles mechs; defeating them and continuing north-east yields a Magitek Shield.

To find the Drillbreaker weapon, go to the south-eastern wing of the base. Locate a warehouse and head to its left side. Turn north to find a small shed near a fence, where the Drillbreaker is on the ground.

Return to Hammerhead and show Cid the Drillbreaker. It requires a Magitek Core for an upgrade, which you should have from Chapter 13 or can find shortly.
