When I'm fighting Geovishaps, I make sure to have a shield character with me to tank the incoming damage. Geovishaps can pump out severe damage with their attack patterns, and with infusion, things get ferocious. You will be dealing with an annoying enemy who can jump in the air to your location and deal elemental damage to your characters. While the Geovishap won't change different elements on infusion, it depends on how well you can tackle that damage. I recommend you have a shield character in your team to tank the incoming damage and save your character from falling. The geovishap has unique attack patterns that can damage your characters, and having a shield on your character will help absorb that damage.
