This is it, the very end of your adventure inFantasian Neo Dimension, and very possibly of all existence. Jas wishes to turn the multiverse to Zero and let everything become nothing. A gaping void, like that of Yim. You can’t let that come to pass.

With the power of a god on his side, Jas doesn’t make it easy. Going through multiple phases and never giving you the chance to save inbetween, Jas is as much a challenge as he is a marathon. Get ready, as this is easily one of the hardest battles in the entire game.

How To Defeat Jas' First Phase

Party Set-Up

Jas is a three-stage boss fight, though the first two are back-to-back. As such, our set-up here will be for the first two fights.

For the most part, we’ll only be using a team of three -Leo, Cheryl, and Ez. This applies to both fights, both Valrika will have a bit more presence in the second phase. We were around level 60 facing Jas, and had unlocked the vast majority of the Growth Map.

The party facing down Jas the Absolute in Fantasian Neo Dimension.

That said, here are somekey skillsto look out for:

In his first phase, he mostly just uses the same attack, though he will stillattempt to put element weaknesses on the party. As such, Leo, Cheryl, and Ez should all be equipped with a Blue Quartz to prevent this. When doing this, he will also cast a random status ailment, so we have a few ways to prevent this as well.

With this, the only ailments you party should be subject too are attack and defense down, which Ez can easily rectify. Beyond this, equip aRuby XL on Cheryl, a Large Jade on Ez, and either a Ruby XL, Emerald L, or Opal XL on Leo. Leo should also equip his Tyrfing weapon and have it upgraded all the way toRagnarok, which requires Deus Augite found in the God Realm.

This is the grand finale, sodon’t be afraid to use Elixirsto fully heal the party where necessary.

Battling Jas

In Jas' first phase, he doesn’t do too much. He almost exclusivelysummons elemental orbsaround the environment, and then attacks the party with them on his next turn if they’re not all destroyed.

At first, they will always be of a specific element and only a few of them, so just destroy them with the strongest element moves you have. He will also attempt to cast elemental weakening and a random status effect on you while setting up this move, though the Blue Quartzand other precautions prevent this.

Near the end of the battle, he will start to summon a great deal of elemental orbs, sotry to save up your Tensionskill to be used here.

Thankfully,Jas is weak to Attack and Defence Down, so keep these active on him at all times, prioritising Attack Down. After Jas gets low enough on HP, he will cast Attack, Defense, and Speed up on himself. You can either take them away one-by-one with Leo, or bring out Valrika to use Dispel.

The real tactic to damage Jas during this phase is Cheryl. As has been the winning strategy, you want tocast Concentrate, Double Charge, and then use Blizzard Strikeon Jas, ideally when he’s already weakened with Helm Bash. This can potentially take out half his HP in a single attack.

Support Charge can activate when Cheryl uses Concentrate, potentially saving you a full turn.

And that’s it for the first phase. After it has ended,you’ll be given a bunch of EXPand continue straight into the much more challenging second phase. Your HP and MP also carry over, so be wary to recover if you need to.

How To Defeat Jas' Second Phase

Seeing a challenge is clearly on his hands, Jas stands up and starts unleashing a great deal more attacks on the party. He still follows a pretty clear pattern, though witha greater variety of movesthis time around.

Instead of just summoning orbs, Jas will actually attack the party this time, and willunleash three attacks in a single turn. This always follows a specific pattern though. He will cast two elemental attacks, which hit. at random butnever the same person twice, and then uses Godly Pulse, which debuffs a party member while buffing himself. Again, the Blue Quartz and other precautions are a massive help.

Every few turns,Jas will summon two orbs to his left and right. During this phase, he is completely immune to damage, so focus all your attacks on the orbs. If destroyed, Jas will lose his turn, allowing you the chance to get in a few hits on him and extra debuffs.

Avoid using area-of-effect moves like Arrow Rain or Knight Impact here. If Jas is in range at all,he will nullify the entire attack.

If you only destroy one orb, or none,he will unleash Magna Ray, which attacks the whole party for quite a bit of damage. This can wipe the party with both orbs, so make sure you destroy at least one no matter what. Cheryl with just a single Charge and Blizzard Strike is more than enough to remove one.

Following Magna Ray, whether it hits successfully or not, Jas will cast Godly Heal.This restores around 10,000 HPto himself but that’s more a slight nuisance than a massive issue at this point.

The last of Jas' moves isDeluge of Blades. Look familiar? This is the exact same as Vam’s move, though with a whole lot more swords. Without using a Tension Skill, it can be pretty hard to actually destroy all these swords (though not impossible). The move weakens with each destroyed, and is canceled entirely if all of them are destroyed.

If you don’t think you can destroy all of them, take down as many as possible and thenboost your defense, restore HP, and start guarding.

And that’s all for this phase. He’ll keep repeating this pattern as he goes,giving himself buffs all the while, though it’s fairly manageable if you don’t get too greedy with your attacks. Take your time with it.

How To Defeat Jas The Absolute

So, we’re in the final phase now. Thankfully,we won’t be making too many changes to the party hereor our set-up, though there are some core skills and such we want to make sure we have.

To start, Jas won’t be using any elemental weakening effects during this phase, soyou can sacrifice the Blue Quartz entirely. We gave a Ruby XL and Opal XL to Leo, and attempted to boost everyone else’s defenses and HP with Emeralds and Opals. You’ll still need your ailment nullification though, so keep those as-is.

We’ll be using two parties this time around,one for attacking and another for defending. Jas has some powerful moves in this phase that can’t be canceled at all, so you have no choice but to tank them.

So let’s get underway for thecore skills. In addition to what we already had, we should get:

Almost everyone has a role in this battle, save for Tan and Prickle. You may have to use the Tension skills from other characters as well, so it’s worth fully upgrading them for everyone that you may as well. If you have excess points or SP Capsules, it’s worthinvesting in the stat boostsin the Growth Map to give you a little bit more of an edge.

Battling Jas The Absolute

Clearly, what we’re fighting now doesn’t quite resemble Jas anymore, but he’s also at his absolute worst right now. Similar to his last phase,he can act twice in a single turn, though only with elemental attacks now. He will be using a special move almost every second turn though.

Skipping ahead for a moment, we want to prep our back-up team.We started this battle with Zinikrin our party so that he could get Ez’s buffs, and then had him cast Iron Wall. On the second turn,have Zinikr cast Concentrate, and then swap him out for Cheryl. He will retain those bonuses for when he needs them.

As before,Jas is still weak to both Attack and Defense Down, so use Leo to inflict those, and have Cheryl prepare her typical Concentrate-Double Charge-Blizzard Strike. Outside of any of the special moves, this is the pattern to keep across the whole battle.

Ez will be support the whole fight, somake sure Quick All is active at all timesto give you as many turns as possible.

The first attack to look out for isBig Bang. Jas moves to the side of the arena and starts charging an attack. This can’t be canceled, so debuff Jas as much as possible, get some hits in, and thenswap in your defensive team. This is Leo, Zinikr, and Kina. If you don’t have time to take out a certain member, Kina can use Resurrection on them on her next turn.

The next two major moves areBlack Hole and White Hole. The former willsuck away party membersuntil only one remains for every turn it is active, returning them when it is destroyed. The White Holesummons more enemies each turnuntil it is destroyed. They are weak to Holy and Darkness respectively, so use buffed Zinikr and Cheryl respectively to destroy them.

The Black and White Holes haveno effects on their first turn, giving you a chance to destroy them before they can do anything.

Near the end of Jas' HP, he willsummon a Black and White Hole in a single turn. This can be frightening at first, though as long as you have both Cheryl and Zinikr, it’s no problem.

Next isSupernova. This is one of Jas' most powerful moves. He will useSuper Buffon himself like in his second phase, and summon a massive amount of elemental orbs to the side. These have a massive amount of HP, making it very difficult to destroy them all. As such, you’ll be destroying as many as you can and thenswapping in your defensive party.

Whether or not you destroy all of the orbs, Supernova will still be used. As such, verify touse Dispel to remove the effect of Super Buff, and have Leo use Blade Break for good measure. The damage scales by the number of orbs remaining, and will easily wipe the party if all of them remain.

That’s mostly everything. Jas will keep on this pattern until he gets to around 50,000-60,000 remaining HP. Then he will use the moveBeginning of the End. Ominous. Jas gives you five turns to fully finish him off, or else it’s aninstant game-over. On the plus side,he will only use a single elemental attackon his turn now.

Obviously,Quick All is essentialhere, and you’ll want toapply Defense Down to Jasas well. Beyond that, we’re going back to ourtypical Cheryl comboto finish him off. Keep your cool here and start unleashing your strongest attacks. Fire Samidare, Radiance Strike, Rudy Strike, everything.

Above all else though, make sure Cheryl doesn’t die.you may’t afford the turns needed to set her up again, and you’ll only have one chance to pull this off. Try to use her Tension skill if it’s available to really maximise your damage.

And that, finally, is Jas fully defeated. Now you get some small interactive sequences to deal the final hits, and head intothe final few cutscenesof the game. Congrats on beating Fantasian!
