To acquire the Hashmal Esper, you’ll need to continue the story until you reach Pharos - Third Ascent. As you venture higher up, you’ll encounter Hashmal and you must defeat him to be able to call upon him in battle.

As a boss, Hashmal can be fairly easy, depending on your party setup and available skills. His normal attacks can inflict Disease, so you will want some people in your party set up with Serum/Cleanse/Remedy (Remedy Lore 3) gambits to get rid of it as soon as possible. He can also buff up his normal attacks’ damage by using Battle Cry. In addition to those two things, Hashmal has access to a skill called Roxxor, which is an earth magickal attack against one character. His ultimate attack is called Quakeja and as its name suggests, it’s an earth-elemental skill that will hit everyone and has a chance to inflict Slow.
The biggest thing that makes this battle simple is the magick, Float. Not only will this make Roxxor miss, but it also makes Quakeja miss, meaning the only attacks you have to deal with is his normal ones. Of course, you still have to contend with the Disease from the normal attacks. He is weak to Wind, absorbs Earth and is immune to all other elements, so have your Black Mage use Aeroga until he gets low on health, which is when he’ll erect a barrier to block all magickal damage. At this point swap your Black Mage out or switch to a melee weapon and before long, Hashmal will go down… and you’ll have a new Esper under your control.
