Some general questions about mechanics

[Fiona Kaenbyou]

Picked this game up because the series has a good rep. Middling on it so far, and I wanted to ask a few questions about things I wasn't sure of to try and rectify that.

For reference, I just made it to floor 4 and my party's around level 15 so I'm at a crossroads for character builds.

1 - Are there any wikis etc with more detailed information on skills/party builds/etc? I usually play these games with a JP wiki so I don't waste my skill points on stuff that doesn't work, but I haven't been able to find a source like that for this game. My usual site (spoiler.jp) only has a guide for DT 2-2.

2 - Is there any consistent way to trigger Joint Skills? The option comes up entirely at random for me and I have no clue why. Is it to do with turn order?

3 - Failing that, is there any other way to see enemy HP as a passive or a class skill? It seems really silly to me that you can scan/seal an enemy and know exactly how much HP it starts a fight with, but the game then expects you to just keep track of damage in your head unless you trigger the Joint Skill that shows you the HP stat explicitly. It makes sealing really cumbersome, which sucks since it seems to be the most reliable way of making money at this point of the game.

4 - Is there a better way to farm equipment beyond just running random encounters and hoping you get lucky buying from Roku? My drops so far have been pretty unfortunate and my physical attackers really aren't contributing much as a result.

There's nothing that doesn't really "work" in that sense, but there are certainly skills better than others. You also will have plenty of changes to respec characters later, so don't stress it too much.

2: All of the Joint skills, to my knowledge, require their characters to have uninterrupted turns between them; Meaning, if a skill requires x, y, and z, then the turn order needs to be x, y, z, a, b, c...

The order itself doesn't matter (zyx, xzy, etc), but they need to be next to each other.

3: I'm not going to defend sealing at this point; I'm in the post game and I still think it's a PITA.

4: No. But trust me, you'll start getting better equipment before long.

Do the side dungeons. You should have unlocked Nearby Forest by now. Either bring Flashlights or the Light spell since that place has fake walls. You should be able to get some pretty good gear from chests there. Go Dark Knight and max out Berserk (and War Cry too of course) and your Fighters should deal unrivaled damage for a long time.

Also more specifically about the wiki, there's a page with skill guides for all the classes, as well as endgame gear recommendations:
