Star Ocean Blue Sphere - English - Cave of Trials (Siren Ruins) pt.10 Gabriel Celeste & Iseria Queen
Final floor! Congratulations on making it this far. Make sure your party is fully healed, double check all equipment and get ready for the two hardest battles in the game if you have all 10 rings. Two screens up will be the first battle, Gabriel Celesta. He’s not a push over and if you’re playing on a Gameboy like I was, lock in. There is no second chance like using save states on emulators. You lose, all that progress was gone. But if so, you made it to the final floor once, shouldn’t be that hard to do it again.
Now if you do manage to beat Gabriel Celesta, he’ll give you the 10th Ring, the Ketel Ring (Keter Ring JP) after he fades away, Iseria Queen will only appear if you have all 10 rings in your inventory, if you don’t, she won’t appear until so.
When speaking with both Gabriel and Iseria, they’ll give you a choice if you want to fight or not. I’ve lost before even with bloody armor but that’s because Percis does almost zero damage in this fight. I know what it’s like to lose all these hours of running through the dungeon for the first time. If you choose to fight, the battle begins. If you choose not to fight, you’ll be warped out of the dungeon.
A good safety strat is to beat Gabriel, choose not to fight Iseria so you can save your game and make the hike down through the dungeon again, she’ll be there waiting for you.
Now for the battle, both are the exact same minus the element weakness, they have incredibly high resistance to special moves so only use them if you’re trying to get some breathing room. Better to use your regular attack and combos. Both bosses will rush you and without bloody armor or max stats/equipment, whatever character gets hit in the combo is most likely KO. Only attack when there’s an opportunity. If you have bloody armor and the healing items to do so, keep trying to create and opening by moving back and forth and chaining a combo. If you don’t have bloody armor, be very careful an no matter what, keep one character alive at all cost.
You also want to make sure at least one of your party members is only healing duty. Make sure to set their formation command to Preserve so they “try” to stay out of combo range. Soma, Resurrect Mist and Holy Mist will be your best friends in the fight. Lastly make sure you have on the correct elemental weapons. Gabriel is weak to Light and Iseria is weak to Dark. If you land a few hits with their correct weakness, you’ll see their HP drop a bit. Chain a combo like I did with Bowman and Dias and it’ll be over in no time.
Good luck, you got this.
Gabriel Celesta (boss) HP 20000 weak - Light
Iseria Queen (boss) HP 20000 weak - Dark
After you defeat Iseria Queen, you’ll receive the strongest weapon in the game…. For Rena. The Glance Reviver (Grand Reviver JP) Att 250 Mag 200 Hit 100 Element Light. All Spell Damage is boosted by 50% You’ll be warped outside. Congratulations on your win!
Lastly, if you want to collect the monster data on Gabriel and Iseria, find the old man in Rupert Jungle. Warp to Garp Ruins, he’s a few screens away. Down, down, left, left, up. You’ll need a large amount of Fol to purchase both data’s.
Thanks for joining me and playing Star Ocean Blue Sphere. This game means a lot to me and I hope more fans of the series get to experience this story and gameplay.
Star Ocean Forever.
