Instructions
Head to the island of Xeroph and look for a Golem. Golems look like large, brown statues made of bricks. When you find a Golem, talk to it and choose "Recruit." If you cannot find a Golem, you can synthesize one using a Gigantes and a Rockbomb.
Find and recruit a Metal Slime Knight or a Buffalogre. Metal Slime Knights are a combination of a green Knight and a silver Slime. Buffalogres are large, yellow monsters with horns and a purple mane. To get a Metal Slime Knight, search Terrible Island. To find a Buffalogre, explore Tarturus.
Go to any town's scout post. Talk to the woman at the post and choose "Synthesize." You'll see a list of your monsters.
Look at the monster's charges. The Golem and the Metal Slime Knight or Buffalogre must have different charges to synthesize them. For example, if the Golem has a negative charge, it only combines with monsters that have a positive or neutral charge.
Select the Golem as the first monster in the Synthesis process. Choose a Metal Slime Knight or Buffalogre with a different charge. A picture of the resulting monster, Living Statue, will appear. Tap it to proceed with the synthesis.
Give the new Living Statue a name and then choose its skills. When you finish, you can put the Living Statue in the storage center or take it with you.
