Party dump commentary:
Main character:
Looks like a good build so far.
Just as a reminder (and I wish I could make this more clear in game): Heat Wave, though it does do Fire damage, is a Slash ability. It won't trigger Auraward! Fire Breath and Chilling Touch do though.
Lifegiver Huo Shu:
Good magic mouse.
If you could throw him Tireless, that'd be great, but otherwise, he's in good shape.
Vile Preta:
One solid ranged nuke would be great here. Also a good candidate for Snuff Out. Depending on your preference, I might even consider letting it lose Ghost Bite and Infectious and just going full magic.
Chindi:
Are you looking to go more ranged or more "warp in melee" with this guy? He seems to be starting to lean ranged, with the addition of Healing Charm and Weigh Sin. If that's so, he'd love a ranged nuke... and maybe should find an opportunity to lose Haunt.
Jiang Shi:
Oppressor is an *excellent* choice for a Jiang Shi.
Notably, it will become much better if you can find a Silver Matrix to power him up with: regardless of the modifier, his MaxHP will increase, making it easier to keep Oppressor in play. Flesheater would also help during longer battles, as would Gluttony if you can get access to these. Daring Cut is excellent too: he'll throw it early when his HP are still high, and likely buff himself, increasing his ability to drain later. Yellow Whisper was also a good add here: his Cunning's a little iffy, but Yellow Whisper's a free action anyway, so there isn't much to lose.
If you can avoid getting him killed, this guy should be able to do good work.
Psychic Ilomba:
A solid support demon.
Feel free to ditch Leech Bite, I'd be shocked if this guy bothers advancing much. Draw Wounds may be worth keeping even without it though: since he'll likely hang back, his HP should stay high and leave him some to pass around to others.
Ogre:
Semi-invisible Ogre (Fade) is a scary concept.
Pounce + Juggernaut is particularly nice: if you leap in and Stun the target, but his allies hit you and trigger Juggernaut's speed up effect, you might see your Ogre hit the Stunned target 2 or even 3 times before it snaps out of it. That can be pretty nasty.
Kasha:
Fiery Veil could be useful on your Ogre potentially. Their Magic and Cunning are a little iffy, but given how much he'll probably be getting hit with Pounce helping him lead assaults, it probably will still be worth it.
Veils tend to be hard to find proper homes for anyway: if a character has high Magic and Cunning, they usually have poor Vit and you don't want them getting hit. If they have high Vit, they usually have poor Magic and Cunning, so the Veil doesn't work as well.
The secret is that really Veils are great in either case: on a glass cannon mage, they can help quickly finish off anyone who manages to get close; on a high durability tank, the tank lasts long enough to squeeze out good results even with poor stats
