Recommended Party
With Mythical Gigas blocking or repelling all physical attacks, you’ll need torely on ice, electric, and wind magicto deal damage in this battle.
However, with Mythical Gigas also knowing fire magic, it’s best toleave Mitsuru behindunless you’ve countered her fire weakness with equipment.

We suggest bringingYukari, Akihiko, and Kento this fight.
Though he has access to efficient damage-dealing skills,Kenis usually best as ahealerin this fight. He knowsMediarama innatelywhen he joins SEES, while Yukari won’t learn it until Lv. 43.

While Ken is focused on keeping the team in good shape, bothYukari and Akihikohave two of thebest magic statsof anyone in your party, which they can use to hammer on Mythical Gigas with theirelemental magic skills.
Another strategy that players have found to be effective is bringingsomeone who knows Fire Breakto allow for Junpei and Koromaru to be effective in this battle.

KoromarulearnsAgidyneatLv. 45, andJunpei’s Agilaowill be an effective combo while Fire Break is active.
Recommended Level And Personas
With Mythical Gigas entering the fight at Lv. 48, you’ll want to bebetween Lvs. 45-50for a comfortable time during the fight ahead.
We’d recommendputting your protagonist on offensefor this fight, as Yukari is available as a back-up healer should anything happen to Ken.
With ice, electric, and wind magic able to effectively hurt Mythical Gigas, you’ll need a Persona withgood ice, electric, or wind magic. If they canresist one or more physical damage types, that’s even better, since Mythical Gigas in P3P is primarily a melee-based fighter.
Though you’ll need to beLv. 48 or higherto fuse it,Dionysusis invaluable in this fight. Not only does itresist slash and strike attacks, protecting your MC against two of the three physical damage types, but it alsolearns Ziodyne at Lv. 50.

Mythical Gigas Battle Strategy
Since it’s got enough affinities and High Counter on top of them to keep it safe from physical blows, you’ll need tofocus on elemental magicto deal damage.
Kenusually ends up being thebetter healer than Yukarifor this battle, but it’s good tohave multiple healersanyway for this, as Mythical Gigas is capable of impressive damage outputs.
With Ken focused on healing, keepAkihiko and Yukarion full offensewith theirelectric and wind skills.
Every few turns, it’s helpful tohave Akihiko use Matarundaon Mythical Gigas tolower its attack. With so many heavy-damage moves, you’ll want that stat as low as possible.
Have your protagonist join the battle withDionysusto keep them covered against most physical damage while outputting an impressive amount ofelectrical damageyourself, and Mythical Gigas will go down before long.
