Gigan Toad is one of the simplest monsters in the game: a large toad with Ice elements. The later versions have spells such as Blizzara. The simplest way to defeat this monster is to repeatedly use Thundara or Fira to stunlock or burn to death. Selkies should equip a Thunder on their ranged weapon, while Yukes can abuse their quick casting. Lilties may have the hardest time, as they need to close in on the creature to do decent damage. Clavats can mimic either the Yuke or the Lilty strategy, or use their own stunlock with focus attacks.
