This Seeking Tech guide will show you how to find the Golem summon in Final Fantasy V. This is one of the most useful summons in the game, as it will block incoming physical attacks up to a certain limit.
For the first step, you need to head over to Drakenvale.
Once you get there, make your way to a hilltop area with a lot of bones lying on the ground.
In this area, you should eventually get an encounter with a Golem, Bone Dragon and Zombie Dragon. Your goal for this battle is to defeat the two dragons without harming the Golem.
The Bone Dragon is weak against Break. The Zombie Dragon is weak against Fire and Healing Spells.
With only the Golem remaining, he will thank you for saving him and make himself available as a summon.
Next, go to the Item menu and then use the Golem item in order to add him to your summon list.
