Let's grind necessary abilities that make it easier for our next two bosses.
Note: you don't have to master these jobs, just the required abilities below:
- Two-Handed from Knight Lv. 3, allows you to use a weapon two handed and double its attack.
- Rapid Fire from Ranger Lv. 4 (mastered), allows you to hit random enemies 4 times; each hit deals 50% of the original damage, which gives you a total of 200% damage.
- Equip Ribbon from Dancer Lv. 3 (mastered)
- Blue Magic from Blue Mage Lv. 3 is recommended for two powerful spells: Mighty Guard and White Wind.
ABP
The best place for farming ABP is Interdimensional Rift - Final Floor. You can get between 20 to 35 ABP per battle, except Movers. These guys come in 3 and give a whopping 199 ABP and 150000 gil. However, you'll have to kill them fast or the battle ends with nothing.
There are 5 floors in the Interdimensional Rift - Final Floor; Movers only show up on Floor 2 and 4. However, because King Behemoth also shows up on Floor 4, Floor 2 is a better place.
On Floor 2, you'll always encounter one of the following:
- Gorgimera (2)
- Belphegor (2)
- Gorgimera, Necromancer
- Mover (3) - rare encounter
All of these encounters die in two Zeninage shots, except Movers, which require 4 Zeninage.
Your first priority is to learn Zeninage from Samurai Lv. 2, then you can level up other jobs easily.
- Your entire party should have the Zeninage ability set.
- When you master a job, you can then change to another job, but keep the Zeninage ability.
- During battle, keep spamming Zeninage and set auto-battle.
- If you are low in health, change one ability to White Magic, heal up, then change it back to Zeninage.
- Don't worry about gil; one encounter with Movers is enough to pay for your next 20 or 30 bills.
EXP
It is unfortunate that monsters in Interdimensional Rift - Final Floor don't give any EXP at all. So your best bet is Iron Giant. One Iron Giant gives you 10000 EXP.
This guy commonly spawns in Interdimensional Rift - The Rift Passage. On this floor, you'll encounter one of the following:
- Fury, Death Claw, Sword Dancer
- Red Dragon
- Iron Giant
- Iron Giant (2)
Since all these monsters are weak against water element, the best way to farm with auto-battle is to summon Leviathan and have the rest of the party use Mime.
- Change everyone's job to Mime.
- Set Equip Katanas and Summon on one ally, then equip Masamune and Gold Hairpin to ensure that this ally always has the first turn.
- During battle, the Masamune wielder summons Leviathan; the rest use Mime to recast the summon.
- Set auto-battle and heal after the battle ends.
Another easy way to quickly kill Iron Giant is to use Iainuki (Samurai Lv. 5). This skill has an 85% chance to inflict death on all monsters except Undead and Heavy types. Auto-battle won't work because Fury and Red Dragon are undead types.
Once you reach level 50, the achievement Seasoned Hero is unlocked and you are ready to face the big bosses.
Equipment
Finally, we need proper gear for our party. Open your menu and check if you have at least 300,000 gil (keep farming Movers if you don't have enough).
Head back to The Rift and use Teleport to get out of the Interdimensional Rift.
Go to Phantom Village and buy 3 Hermes' Sandals and 3 Coral Ring (you should already have 1 Hermes' Sandals and 1 Coral Ring in your inventory).

Go back to Interdimensional Rift - Final Floor for our final battles (see 62. Interdimensional Rift for navigation reference).
