I don't consider Jess having Bounce that early, honestly. Bounce is floor 4 for me most likely, and I don't even think I had it before Dhouly even though I only spent points on Staves and Whips for the whole game
Are you sure you're not misremembering? Or did you put points into Whips beyond TDL (I did too, oops)? DQ8 skill growth isn't random. According to the dungeon Jess workup I did, she can actually grab Bounce on floor *1*, but even assuming that this is too aggressive a level to pick... Floor 2, 20th level, Jess has 67 skill points to play with. TDL is Whips 23. That leaves room for Staves 44, way past Staves 21. On floor 2.
As another note on Demi / Wren, once the defensive setup is finished, aside from Oomphing Lyn Jess can Kasap the bots to negate Barrier. Purim can also power up her (Oomphed?) kung-fu. They can't stall THAT long, so it's not too bad a resource hog.
Okay, now as for Glen...
WCYD? sounds like it utterly annihilates the Dungeon in general, and if it works as it sounds like (All ST fails, bullets permitting) than it should probably be banned from Firefly. If it does have holes - like to status - then maaaaaaybe Glen's team might lose, but I doubt it. So let's see if Glen can beat the dungeon without WCYD?. Also, for future reference, it would be good to settle the "What does Suction actually do?" debate. (Ah, WA1o. Easy enough with cheesing stat downs that I never had to bother with the lesser cheeses.)
Also, as a note, I see Firefly as turning off if the bearer has a *fatal* status like Stone, but not one that doesn't end the fight. So BoF1 Hold, no, but FF4 Hold yes.
Team Glen | Cecilia, Raquel, Lilka, Jane (Firefly)
[Floor 3a]
*All MT is ST and targetable
Team Glen vs. Eiko, Garnet and Rydia - See first post, but Defend making Odin fail makes this easier.
Team Glen vs. Geddoe and Hugo - Reflect on Jane, then revival from the phsyical beatdown. Raquel takes care of business. (Edit: If the team goes for fast spells that beat out Ceci's reflect, then don't even bother with Reflect, just stick to revival.)
Team Glen vs. Lulu and Nina1 - See above interpretation note. This means that even a Held Jane eats the Fatal Cait Sith at worst after Ceci's Reflect. Can Raquel & Lilka kill Nina1 in one turn? Sure, I say, meaning that Nina doesn't get a chance to do anything bad to anyone else on Round2 with Jane dead.
Team Glen vs. Demi and Wren - Even if Demi / Wren offense is respected enough to be able to flatten Jane every round, Ceci & Lilka should be able to keep her on her feet. Raquel will have spent her skill points on grabbing Moonlight early? Forget the level it's at but I assume it's reachable if she throws away Class lvl. ups. Intruding Raquel takes down the bots even if they throw up defenses.
Team Glen vs. Boss Magus and PC Magus - Reflect. Magus's physicals with no one dead are awful. Also Magus's counters to attacks get reflected at himself and break his own barrier. Oops.
So Glen passes even without WCYD? to me.
