Though Kyra is so far proven to be the fastest and safest character to use against the final boss, if one ever plans on running this game at a charity event, marathon, or other event where incentives are a key part, a big incentive may be to have the option to use one of the other four characters and alter your strategy accordingly. Or, perhaps you just want to mess around and try one of the other characters, especially if you know you won't PB. This guide should serve as the purpose of doing just that.

Generally, final boss Macros would look like this: A: Wren - Barrier, Rika - Saner, Kyra - Warla, Chaz - Crosscut, Rune - Swift Helm B: Kyra - Medice, Wren - Flare, Rika - Attack, Chaz - Attack, Rune - NaWat C: Rika - GiSar, Kyra - Guard Rod, Wren - Recover, Chaz - Attack, Rune - NaWat D. Kyra - Medice, Wren - Flare, Rika - Double Slash, Chaz - Crosscut, Rune - NaWat E: Kyra - Star Dew, Rune - Guard Rod, Wren - Recover, Rika - Double Slash, Chaz - Crosscut F: Rune - Rever, Kyra - Medice, Wren - Flare, Rika - Double Slash, Chaz - Crosscut G: Chaz - Rever, Kyra - Medice, Wren - Flare, Rika - Double Slash, Rune - NaWat

There is a slight variance where Rika takes the place of Rune in Macro E, depending on your strategy. Using this as a basis, you can change your strategy according to the notes below.

Gryz

Gryz is actually probably the next safest character to use behind Kyra, but it requires you to also buy a bunch of Trimates in addition to what you already purchased. 8-10 Trimates would suffice... if you have the space. The other issue it runs into is that replacing "Krya - Medice" with "Gryz - Trimate" in these Macros would mean that you would have to manually enter commands if Wren is the one that needs healing. Other than that, "Kyra - Star Dew" gets replaced with "Gryz - Star Dew". Also, it sets you back about a turn because you would have to have Rika use Deban during the 2nd turn. During Phase 3, Cancelling will give you a harder time and you may have to forego using Deban during that phase entirely. Wren and Gryz should be able to withstand an unmitigated normal attack from PFD, others might not. Place Gryz behind Wren.

Giving Gryz the Guard Shield and Reflect Shield make him able to withstand any attack the PFD throws at him. His biggest problem is his speed. While Saner will give him a lot of agility, it still may not be enough. Equipping him with the Swift Helmet can help, but you'd be pushing it a bit for Rune to be able to help with healing as well. In this case, you may want to use Rika to aid in healing if you are finding that Rune isn't getting the Guard Rod out in time.

For downtime, Gryz can't do much on his own. This can be remedied a bit by taking Hahn's Mahlay Dagger from him and having Gryz use it as an item during battle. It does close to 160 damage per shot, which isn't much, but is better than nothing.

Raja

Raja's build is quite a bit cheaper, but also much riskier. You would need him at Level 33-34 just to stand a chance of surviving Megid. Anything lower and you really risk Raja getting one-shot by Megid. He needs 2 Psychic Shields and a Psychic Circlet in order to up his MDef with hopes of surviving. A Phantasm Robe can help with agility issues, but it leaves Raja open to die from Megid. Keep Raja in the very back to make this work better.

Replacing "Krya - Warla" with "Raja - Blessing", "Kyra - Medice" with "Raja - NaRes" and "Kyra - Star Dew" with "Raja - GiSar" should take suffice. You can also replace Macro G with "Chaz - Rever" to "Raja - Regen" then move Chaz further down the Macro with "Chaz - Crosscut". Regen acts as a Sol Dew at a hefty TP cost. During the 2nd turn, Raja NEEDS to use the Swift Helm in order to keep up. After Cancelling in Phase 3, use your normal buff Macro, but if you take Megid to the face, have Rika use the Star Dew in place of Raja for the turn while he uses the Swift Helm, then return to your normal strategy.

During downtimes, Raja can throw out St. Fire. I recommend doing this on the first two phases to try to bring them down sooner. If you wanted to, you could take Hahn's Mahlay Dagger and use that for damage outside of St. Fire. Other than that, Raja should use Ataraxia if his TP drops below 120 and you have downtime.

Hahn

Hahn's speed is the biggest factor here and you may be put at the mercy of the RNG even moreso. Level 33+ would be the most ideal, so you would need to grind a bit more if you are using him. His equipment is actually really good, and giving him the Plasma Field in place of his Mahlay Dagger will help with the process and should negate PFD's normal attack. The only way to get him to work in battle is by making him use the Swift Helm. Put Hahn behind Chaz but in front of Rune. He could possibly go behind Wren and in front of Rika, though I haven't tested that yet.

Replace "Kyra - Warla" with "Hahn - Vision" this is the only buff he can give the party, which should make Chaz and Rika's normal attacks hit and increase the crit chance slightly. On the 2nd phase, you will need to have Rika use Deban and Hahn use the Swift Helm. Other than that, treat this fight like you would if you had Raja. "Kyra - Medice" is replaced by "Hahn - NaRes". "Rune - Guard Rod" is replaced by "Rune - Star Dew" and "Kyra - Star Dew" is replaced by "Hahn - Guard Rod". Much like using Gryz or Raja, you will have to manually enter in a command if Wren is single-targeted.

During downtimes, Hahn isn't much different than Kyra. NaWat is quite powerful, but if you're getting low on TP, use Astral, though barring straight physical attacks, you shouldn't have to worry about using up Hahn's TP. During Cancelling, you will have to do the same thing you would do with Raja. Use your buff Macro as normal, use Rika as your main healer while Hahn uses the Swift Helm.

Demi

Not likely coming anytime. Demi makes the battle go a lot longer and becomes very difficult to get it working right. Demi offers NOTHING to the party other than a mass revive. Her Barrier is weaker, she doesn't have much more HP than Rika, her only means of attack are her gun and Phonon, IF you picked it up. If not, you'd have to go to the Plate System to get it and even then you only would have 3-4 charges at her current level. Not only that, having her in the party pretty much makes the final battle HARD mode at this point. You end up losing a human, so it means you have to change your strategy entirely.

NOTE: The following strategies have not been tested and probably won't work.

Demi needs to be at least at Level 34-35 to even have a chance of out-turning PFD. Her role would be damage dealer, but not a good one. Mahlay Dagger might do more damage than her normal attacks. Rika would be forced to become the primary healer and you would need a TON more Star Dews (close to 20). "Kyra - Medice" would become "Rika - NaRes" or "Rika - Trimate" while Demi would just Attack in just about any Macro. Megid would be ugly as both Wren and Demi would need to use Recover while Rika and Rune would be forced to heal, technically cutting the damage you would do by 25-50% per turn. In such cases, you may be better off just leaving Demi dead.

There are a couple of small benefits to Demi, however. Putting her behind Wren gives you a second tank who can self-heal, meaning Rika can get her chances to attack. Demi can also be used in a mass-revive Macro, having her use Medical Power and someone following up with a Star Dew. Hopefully you don't have that situation arise, however.
