Gigas is a popular term for races of giants in fantasy games. Gigas is a Greek word meaning "giant", originally used to describe the race of Gigantes in Greek mythology.
Secret of ManaEdit
Three creatures known as "Gigas" are boss characters. There are three of them: Fire Gigas, Frost Gigas, and Thunder Gigas.
Strategy: Take some time to level Undine to level 1. Also, upgrade any weapons you may have orbs for and level your characters to at least level 13. If Popoi's Undine is level 1, this battle should be a breeze. Don't forget to buy Faerie Walnuts! Have Faerie Walnuts in your inventory from this point on!
Fire Gigas's favorite element is...well, fire! He does have some pretty high level spells, including level 4 Fireball, Lava Wave and Exploder. If you stand directly in front of him, and he pounds the ground, expect a party-wide Exploder spell about a second later. So in other words, stay away from him. He'll still cast Lava Wave, Fireball and breathe Fire Breath, but you'll take less damage from those spells. When your party gets low on HP, have Purim cast her level 1 Cure Water. Have Popoi use Freeze or Energy Absorb to quickly dispatch the Fire Gigas. Freeze will smack him for almost 250-300 damage a spell.
Strategy: Make sure that both Purim and Popoi's fire magic are level 3. Also, have your characters at or above level 27. This boss is similar to the Fire Gigas you fought in the Underground Palace, only this one specializes in water attacks rather than fire. His most annoying attack is his Freeze Breath. What he usually does is materialize, blow Freeze Breath on somebody, and then disappear again. However, he can also cast level 6 Freeze or Acid Storm. Although, his magic is level 6, you won't take that much damage from it. What's strange is that he will sometimes equip your party with level 6 Ice Sabers! Anyway, when he materializes, have Popoi cast level 3 Exploder or Fireball or Lava Wave (it doesn't matter, but Exploder does more damage). Purim can also fight back by casting her level 3 Blaze Wall or Fire Bouquet. Randi should just attack.
Strategy: Thunder Gigas will present some sort of challenge to you, that's for sure. Blitz Breath will definitely be your worst nightmare in this fight...this does over 400+ damage to a single character. Standing in front of him when he's materialized will cause him to slam the ground, resulting in you eating a level 7 Thunderbolt. Plus, he will try to Silence you or cast Thunder Saber on you. Gnome gets to have his fun with this boss, however, so let Popoi cast level 7 Earth Slide often. Gem Missile works well too, it just doesn't do as much damage as Earth Slide. Purim needs to be curing damage from any stray Blitz Breath attacks, and Randi needs to be attacking.
