Djinn: Yes. And a pre-emptive no.
Grandia LLG:
Saki, 3x Private (Justin 8, Sue 6, Feena 8): HPs are in the 50-60 range. The scrubs get easily dispatched with some quick AoE blitzing in the start. Saki herself has Power Lariat for 40ish damage and some weaker attacks. Diggin', heal, be careful. Not too bad, takes a while and some items though.
Nana, 3x Private (Justin 8, Sue 6, Feena 8): Like the previous battle except Nana is terrible. Her yo-yo specials do something like ~10 damage. One of them is MT, oh no.
Mio, 3x Private (Justin 8, Sue 6, Feena 8): Mio has Balloon, which has entirely unpredictable targeting, usually hitting 1~2 PCs for 1 damage and POIZN+sleep. Stun Gun does 30+ damage and adds Paralysis. While the occasional poizn hit, Grandia Sleep and Paralysis are pretty unimpressive on their own, all three add up to a whole lot of turn loss to the point it's not impossible to see Mio lapping your party. Justin died at one point to POIZN after a barely survived Stun Gun hit. Poor Justin. Wasn't really close to a reset though.
Scrubs on the train: Skill Exp fodder. I do have one character death due to underestimating Sergeants though (39 damage Wave Cut? Ow)
Scrubs on the mountain: Sergeant parties. Easy to deal with when you take them seriously.
You can't run from End of the World randoms. Of all the places for Grandia to make sense. I get caught by one formation of sonic bats no matter what, oh well. There are a few forced fights guarding switches and such in End of the World too, culminating in...
Emerald Birdx2, Clay Bird (Justin 9, Sue 7, Feena 10) (stopped counting resets): Good grief. Emerald Birds have an AoE attack that does 40 to all and paralyzes and none of their other moves are very nice either. 265 HP is sadly not entirely trivial to this party, and I have a number of resets on the fight, one getting caught by a formation while running from the save point, and an absolutely infuriating one where I actually get stuck in the world geometry. I finally manage to ambush this formation and blitz two birds before they manage to kill anyone, then heal and mop up the last one.
Gadwin (Justin 9): yeah well
The randoms at Mt. Typhoon splatter non-Gadwin people if they get an ambush. This and the Emerald Bird fiasco finally make me upgrade from New Parm armor. >_> This is a very noticeable upgrade, reducing taken damage by ~20.
Serpent, Hot Head, Nice Head, Mean Head, Cool? Head (Justin 9, Sue 8, Feena 10, Gadwin 30) (1 reset): No points for guessing the MVP. The rest of the party has 62-77HP, Gadwin has 273. You need to either kill the Serpent (1000 HP) or its heads (423-800HP each)to win. Serpent itself uses 4Head Attack, doing 20ish physical damage to an AoE. Hot Head is fast and does 25 fire magic damage to a giant area. Cool Head uses Stun Gas, doing 0-10 damage to an AoE and causing paralysis. Mean Head's Killer Bite does negligible physical damage and causes moveblock. Finally, Nice Head heals all enemies for 100 every time it gets a turn. First time through I start slow, buffing myself up with Diggin', the works. I soon find out I have no way to cure moveblock and seemingly can't keep up with the healing with the dragon getting a whole lot more turns than I do. Oops. Second try, I blitz the Mean Head so I can't be permanently screwed. Feena gets Moveblocked though! I have no reason to care. Feena supports Gadwin with WOW!, occasionally healing herself with items, Gadwin does the damage, Justin and Sue can't keep up and die. Oh well. I take out Hot Head, bringing the hydra's damage output to levels manageable by Alheal. I resurrect Justin and Sue, then start grinding down the hydra. Cool Head falls, Nice Head falls and the Serpent dies.
