Aurora Ruins | Disc 3 - Side-quests Blue Dragon Guide

After approaching the map marker, land and enter the strange building. Take Kelolon Necklace from a chest and use the elevator. A boss battle is upon.

Boss - Stonesaurus

Start with attacking the enemy's head. It's best to use wind magic against it. You have to deal a lot of damage to it before it falls off and makes the monster much less dangerous.

After the battle Toripo will give you Lock-On Upgrade Part A - one of the upgrades for your Mechat.
