I highly doubt the challenge is just "walk between all these ropes hanging from the ceiling." They are probably animated and will try to attack and bind anyone who gets too close to them.
Currently, we have three options:
1. We accept Dahlia's offer, pushing back our encounter with Alide. Pros of this option are we avoid a fight. Con is probably going to involve rope bondage and sex.
2. We retreat, not really gaining anything and only losing time.
3. We fight Alide here. Pros, she hasn't set traps here (separate from the ropes) and the ropes will impede her movements as much as ours. Cons, we have to fight Alide.
I'm leaning towards fighting here. Alide hasn't had the chance to set up traps, and her the ropes here will be as likely to trap her as us. I think it's better to deal with Alide sooner than later. Also, we've tried Identify on Alide before and some of it was covered up, but that may have been done to hide Alide's role and abilities as a floor monster, so let's try it again to start things off.
As for tactics:
Goma, use the horn and then try to use Puppet on the ropes, I doubt it would have any effect on Alide if used on her directly but maybe we can use the ropes to bind her.
Sally and Beck: focus on getting between Yulia and Alide, you're our primary tanks and can come back from damage that would be fatal to anyone else.
Cherchiel: Use the carapace armor to go into ball mode, that should keep the ropes from grabbing you while letting you charge towards Alide to mow her down
Yulia: Use Open Sesame paired with single-target offensive magic like icicle, lightning strike, and force lance to make sure it hits Alide without damaging the ropes around her (since we're relying on those to bind her). Be ready to shift to healing as the situation requires, especially Great Cure if anyone gets poisoned
Isalia: Your plasma rifle has three charges, and I don't see any point in saving them given the circumstances, so look for an opportunity to shoot Alide the moment she gets caught
Lri: Same as Isalia, but earlier in the fight throw up illusions of more ropes and attacks to confuse and distract Alide
Lemiel: Use your Angelic Rays to hit Alide from a distance, and be ready to provide healing.
Maple: You're also on sniping duty, use that rail gun bow to get some damage in from the start of the fight since you and Yulia are likely the only ones who'll be able to hit Alide before she gets bound
Talwa: If Magic Armor can be used on allies, spread that out to prevent fatalities, your wide-range fire magic should be saved since Alide can likely avoid it and it will get rid of the ropes that can impede her movements. Worst case, use it if we need a big burst of damage to finish her off and it looks like no one else can deliver it
Alide is likely the most dangerous opponent we'll be facing (unless we have to take on Dahlia or any of the other Tower admins, but it seems like Alide is the only one we're being forced to fight outright) so feel free to use whatever potions and plasma attacks or anything else that are necessary.
All that said, if I get outvoted on accepting Dahlia's offer or retreating, so be it
