Veteran role-playing game (RPG) fans know that most titles host a slew of secret locations and items that only eagle-eyed gamers will discover in a playthrough. Square Enix's "Final Fantasy XV" is no exception as there are some weapons in the game that can get even stronger if you let Cid upgrade them for you.

RPG Site reports that as early as Chapter 2, you can meet Cid at the Hammerhead gas station. Talking to him will begin the "Cid Sophiar, Master Mechanic" sidequest, which tasks Noctis with bringing back weapons and materials that Cid can upgrade.

Players who want to get their hands on these stronger weapons must keep in mind that once you begin an upgrade, you must complete other quests or hunts and camp elsewhere. You'll know Cid's done upgrading when he gives Noctis a call the next day.

A Better Drain Lance

The Drain Lance can be found after the final battle in chapter one and is upgraded by both the weapon and a Metal Scrap to Cid. This material can be found near the entrance to the hotel in Galdin Quay.

A Better Drain Lance II

Coeurl whiskers are needed for the second upgrade. The material can be dropped by Coeurls at the Keycatrich Ruins in Leide in the morning.

A Better Auto Crossbow

The Bioblaster weapon is in the Keycatrich Trench Dungeon right before the locked door, and you will need a Cactuar Needle to upgrade it. The item drops from Cactuars, and it can also be found at the Risorath Basin.

A Better Bioblaster

This weapon is found in chapter 2 outside the Keycatrich Trench, along with magitek soldiers. Upgrade it with a dynamo, which can be found at Callatein's Plunge near the Glacial Grotto area.

A Better Circular Saw

The weapon is earned as you play through chapter 2, and can be upgraded with a Sky Gemstone. This item can be earned through the chapter 8 side quest "A Feline Feast" at Cape Caem. The chapter 8 quest will only be available if you finish the "Kitty Catering" quest in Galdin Quay by "talking" to the cat on the docks.

A Better Drillbreaker

The weapon is located at the Formouth Garrison, which is fairly doable with a level 40+ party. The Magitek Core needed to upgrade the Drillbreaker can be dropped by the MA-X Dux enemy in the same area.

A Better Noiseblaster

The Noiseblaster can be found at the Fort Vaullery Dungeon. The Magnetron needed to upgrade it can be dropped by MA-Hoplomachus enemies at Formouth Garrison.

A Better Gravity Well

The weapon is located inside the Aracheole Stronghold dungeon. To upgrade it, you will need a Hyrdaulix Cylinder dropped by the MA-X Patria at enemy bases, and the item is also available in Fort Vaullerey as an item.

A Better Engine Blade

Noctis starts the game with this weapon, and it can be upgraded with a Rusted Bit, commonly found on the ground while exploring. The second upgrade requires a Glass Gemstone, such as in Lestallum next to the Cup Noodle truck. The weapon's final upgrade requires a Sturdy Helixhorn, which drops from Duplicorns or Leukorns.
