Remi makes a good slot 2 character IMO. Her damage is very good, not bad. In addition, bosses DO like attacking 2nd row targets fairly often, so having someone not tanky there will see them get pwnt by his ratsatsu fist or whatever it's called.
I'd try to help but really, I beat him on my first try. I don't even know if I've seen all his moves. I just know that the first phase was the roughest for me as he physically killed off a few of my back row characters, then when he phase changed into elements, it went rather smooth (except for the silent phase, which didn't really kill anybody, but it made me sweat a bit).
ANYWAY. I'm having some difficulty with the final boss, so many hp (even more than the last one), in addition, I'm not sure if I should kill all the adds, or spare one. I notice she never buffs herself up to hell when you spare one, but when you kill 2, the last one seems to go very fast, and all 3 of them are very dangerous when fast sometimes. The left one is almost always at 100% mag, the right one looves 1-shotting my back row people with steel slasher, or deathing them with hyperspace slash.. and the middle one... Well it casts djinn storm, need I say more (even without djinn storm it's by far the worst imo. it casts insta-death too, along with that bs poisen spell that makes your hp go from 15,000 to 1 in less than 1 turn, with 30 poi resist I might add)?
so I decided I'm going to see what each of the 20 floor enemies drop before attempting again, might as well write a mini guide about em too since I'm at it.
Executioner:
Reasonably fast physical damaging enemy. Mystic magic seems to be affective. They don't have a whole lot of hp (my wild guess says 300k), but they do have enough so that killing them before they move should be impossible at the appropriate levels. They are one of the easier enemies IMO, just don't fight them without a tank up front, maybe even 2 if you're new to the floor.
Drops:
flower blade kikuryusei: +72% atk,def,mnd,spd
The norns:
Spawns with 2 of those white cloud enemies you see on floor 19, at this point they should be little more than a nuisense though (though ether flare always seems to do damage if they decide to cast it). Often heals itself for 200k if you try to kill it before the adds, but only once per fight that I've seen. I don't know their HP, but it seems to be approximately 300-400k. I haven't noticed any weaknesses, but they aren't really strong against any elements either. They like to spam random elemental multi target spells really fast. Fortunately they do really poor damage with them. Sometimes they melee with a steel smash though, so you still may want a tank out anyway. One of the most annoying enemies on the floor IMO, even though they are pretty much impossible to actually die to.
drops:
Elder Dragon's Jewel: +16% recovery (yes that's it, yay, not)
Giant Lightning dorfs (I forget their name):
Yeah, they cast lightning...Alot. You know those white clouds on floor 19 that cast it twice for every big spell? These guys cast it like 7 times. It doesn't do a whole lot of damage if you don't have anybody magic weak out, but it really makes fighting these guys a chore. After the lightning spam, they'll launch either 1 last lightning bolt with the same name, only much more damaging (for me it's often 0,0,0,0,0,0,3700 or so) with a chance of paralize, or they'll do some multi-target lightning attack (also often causes paralyze). They can multi-target melee as well. These guys have the most straight forward attack patterns though, they never really surprise you with anything. They do seem beefier than the other trash in this stage though.
Drops:
Armands: 50% atk, +12 TP, wind aff +144, par res+36
Diamond knight:
I don't think these guys do anything but 1-shot your guys slowly. They have no real weakness except low HP (like 250k I think). Just nuke as hard and fast as you can, don't really worry about tanks or defense or anything, what they hit, dies. End of story.
drops:
Scourge: (haven't got one yet, dunno)
Blue robot glass nuk, err cannons:
These guys are a pain. They move faster and faster the more they are hurt, and they hit harder too. They typically open up with a blue laser attack which hits one person. If that person isn't a tank, they're probably dead (they love 1-shotting reimu for me. I even use barrier, but she still gets nailed for over 100k). I like to soften them up by about 100-125k hp. At t hat point, get ready to nuke them down another 150-200k. But make sure you do it as far away from their turn as possible. If you nuke them again and they get a chance to attack, you lose. when at 1/4 health or below or so, they spam (like orin catwalk spam), this red laser move over and over again that will just stomp your entire party in no time flat. It is some kind of magical attack because patchy is the only person who can survive more than 2 hits from it, not many more though.
They are RIDICULOUSLY weak to fire. Royal flare hits for about 170k for me. Ouch. So never ever royal flare them until you soften them up a bit first, or else you might piss em off. They CAN multi-attack the group as an opener (or before they are low on health), and it still hurts a ton, so it's really reccomended that you barrier the group or something. Try to memorize a formula that works for these, I really do not suggest ever fighting these if you're limited to using characters you normally don't use to fight them, if you mess up and enrage them before you mean to, you'll die.
Drops:
Dunno:
Giant 4-legged armored thing:
Spawns with 2 of those similar-looking dudes which are slow moving, and very weak to wind. They cast big earthquake just like their smaller counterparts. It's going to 1-shot squishy casters like Patchy or Kaguya. They however, are not weak to wind, I'm not sure if they have a weakness, but they don't seem to have any strengths. Just try to kill it before it quakes. Or have a group that can take one. They move average speed, but it seems slow at first because they begin the fight with a near-empty action bar.
drops:
Dunno:
Hellfire Demon:
Probably the most difficult enemy. I've seen it cast multi-target death, as well as wind of miasma which does ok damage. It has a lot of health, and if you're lucky, it will summon a Solar demon king as well (which if you don't know was already like a mini-boss itself for floor 19). It can also cast ratsetsu fist (tanks out), and thousand fist khanon (someone dies). They aren't horribly weak to spirit like most spirit weak enemies are, but it is definately noticeably more powerful than spells of other elements. I don't know if they are weak to cold. After chopping off 300-400k health or so. I don't know if they can summon more than 1 demon, I generally don't like giving them the opportunity to try. You may want to run away if your party is already lacking due to extended over-exploration. It's just not worth the risk fighting these guys when they can guarantee kill your guys with thousand fist or that death attack.
