The Backyard

Slot Seed found in the Corner of the room

The Backyard is located in Low Town (Ghotza East) at the bottom floor of the apartment block, which is accessible via the lift in low town when playing as Jansen and Ming during Disc 3.

There is one initial league to fight in, and more leagues open as you provide Magic Keys to Receptionist Bormis. Information about the fights can be obtained by providing various Backyard periodicals to Informant Zelen. Stars are earned for the player's performance in battle, and Prize Exchanger Gleg provides rewards based on the number of stars acquired. Receptionist Bormis will also give the player rewards for winning each battle the first time, and an additional reward is provided for achieving the secret objective for the fight.

While experience is not gained, SP is earned after each fight.


  • Slot Seed - In the middle right of the four barrels.

The Immortal[]

The Immortal[]

If you succeed to get 3 stars on every match, you will unlock "The Immortal" level, which will allow you to play the final boss of this Backyard Arena side quest.

Monster information:
Name Number Type Element HP Row
Immortal One 1 Aerial Earth 175000 Front

Win Conditions:
  • Defeat All Enemies

Secret Win Condition:
  • Defeat Immortal One within 30 turns

2 Star Reward: Slot Seed
3 Star Reward: Quad-Element Seal (Requires Special Accessory skill to equip.)

Additional Information and Hints:
  • The Spells "Divide" and "Reversa" are your friend (Black Magic doesn't work on him). Use Divide with high health, and Reversa after he starts using his "Cube" Attack. Recommended level 70+ Whole Party. Also set skills Persistence, and Crisis Defense. Having all 4 Immortals in Battle will also help so you don't have to worry about dying.

Note: The skill "Lucky 0 Magic Damage" will help more than "Crisis Defense" if you're short on skill slots. If not, use both. Also, don't bother equipping Wind element weapons/rings. The first tip was the best; Divide & Reversa are your friends. The characters who will deal the most damage with those spells are Kaim & Seth ,who're also the characters that deal the most physical damage, but those spells should be dishing out 7-10k damage while attacks with Wind rings will probably only result in 2-4k. No contest there. If you use your other three characters to res & heal (Just enough so that Persistence can kick in again, so don't go wasting any Heal Full's), and occasionally cast one of the aforementioned spells, this battle actually isn't that bad. ~Nemesis55444

    • The Immortal One is Earth Element, and therefore is weak to wind. If you have any Wind element weapons or rings, use them.
    • This fight is based purely on luck, not so much skill. He has one of many spells he uses in counter, and when he gets low enough in HP, one of those is Cube, which takes everyone to about 1-2% HP. If he uses Cube and then double casts Shadowus, which he will do as he's closer to death, that could take you from topped off HP to KO in one turn even with Persistence. Crisis/Complete Defense unfortunately won't save you.
    • The thing to note is that this fight gets progressively more difficult as it progresses, to the point of being almost impossible. You'll want to keep your health up as best as you can to compensate for Double Cast Shadowus and the potential Cube. The best way to do this is to only use a single attack per turn. The first turn of the fight, he doesn't deal any damage. Instead, he just drops a bomb on the GC guage. Have folks in your party with the highest HP they can get, all use Divide (all five of them), do not double cast it. This should get you a SIGNIFICANT start.
    • Refrain from casting buffs. The Immortal One reverse(not negates, reverses) all buffs cast.
