Aegir initial Amaria/Titania fights are separate normally saveable battles, not the later Rayquaza double-boss chain. Static installed850E125/124 and trainer versions0 inspected; do not trigger850E130 until its full chain is separately planned. Amaria opens WaterSurface but Tapu Bulu GrassySurge can change it (Battle_Field.canChangeFE blocks only Underwater/NewWorld). GrassyTerrain boosts grounded Fire1.5, weakens Surf/EQ, ElementalSeed raisesDefense+Ingrain. Celesteela may become grounded by its seed. Proposed lead Volcanion+Magearna with TrickRoom retained: VolcanionFlamethrower into Celesteela, MagearnaTrickRoom; reassess public seed/field and HP. Charcoal strengthens Volcanion fire (currently WaveIncense; change before battle). BuluGrass attacks heavily damage Volcanion; it has487HP356Def and should survive an ordinary unboosted WoodHammer, but protect/switch if focusfire threatens. Magearna gains SoulHeart for either faint; use FC into Bulu and CM only if the surviving enemy damage permits. New Volcarona is weak to SteamEruption; Palkia/Kyogre need Magearna special bulk and fairy damage. Do not spam Surf into Magearna or Earthquake into grounded allies. ZapdosDischarge pairs with Swampert immunity; not with Magearna/Volcanion. Later Titania Marshadow steals boosts with SpectralThief, so target it immediately and avoid overinvesting setup before it is eliminated. Save/pre-entry native frozen roster before each independent fight and open matching trainer music span at interaction.
