Ten seconds
Everyone gets acquainted with each others power and how it works. This is done by Cornelia opening a telepatchic link between everyone, and letting them share their information with everyone while not having to stay in the same spot talking this over. This saves time, and allow other things to get done while she's doing this. She keeps this link up for as long as it is needed.
You already know why I feel this is important. This shouldn't take ten seconds to start up, and again, this last for as long as she desires (if people leave and return, she opens the link with them again, continually sharing new information)
Twentieth second-First minute
Luc is intrigued at Cornelia's ability of invisibility. So while this link is open, they talk about it. Also, while the link is open, Ukoku ask everyone to run down the list of things they think would be beneficial to the fight from their verse.
First Minute
Ukoku unlocks Cornelia's potential (evolved powers and teleportation) and ask her to grab the Heart,The Seal of Phobos and Tooth of Tonga. Since she knows the people who have this, this shouldn't take too long. Once she returns, Ukoku have her hand it to those who've not demonstrated cross-dimension teleporting (Fei, Luc, and Bindt). Everyone teleports to their verse except Luc and Cornelia (Ukoku is going to return to Luc's verse with him)
P.S. During the wait for Cornelia, Ukoku starts to read in on the other teams preemptively and talk with the ones here about it.
Second-Third Minute
Luc and Cornelia teaches each other their patent wind ability (Luc learns invisibility, Cornelia learns oxygen removal/vacuum) while the others are acquiring what they need.
Fei gets Weltall (note: massively weaker than Xenogears. I'm talking not even .33336 its power), about 10 or so firearms, and some battle armor. All this can be gotten from base, from the people he know (he knows the Queen of Shevat).
Ukoku gets the soul gourde and the three other sutras (Seiten, Kouten, and Maten). He gets Seiten and Kouten from Koushu, the person he's working for, and he steals the Maten from Sanzo (which should be easy since he's pwning the hell out of him in a current chapter).
Bindt grabs him a few of those rifles that can even harm a Rynax. Easily obtained from the base that he lives at.
All return afterward. If anything, add an extra minute to that
Fourth-Seventh Minute
Once everyone's back, Ukoku sends Cornelia, along with Bindt, to her world again. She will now work to acquire Horn of Hypnos, Mage Ring and Seal of Nerissa . Since it would have been difficult for her to acquire the Seal on her own, this is why Bindt is with her. With Bindt, it shouldn't take a minute to acquire those.
Luc and Ukoku goes to Luc's world. Luc first grabs the orb that allows him to hold multiple true runes. This shouldn't take no longer than 10 seconds given that it is his (in truth, should I even need to grab it? Wouldn't that be like standard equip?). Ukoku uses his clairvoyance to find the exact person and/or rune Luc wants. For this fight, he desires the Sovereign, Blue Moon, the two halves of the Gate, Water, Viki's Blinking and Sun so they teleport to the intended places and get it (since Ukoku is with him, it's twice as easy to steal, if need be). And so as not to make people think that this takes longer than the intended time, here is an explanation for each rune and how acquisition is made within the time limit:
Sovereign: Last seen on Barbarossa. Since he did a suicide dive, the rune and his whereabouts are unknown. This is, again, why Ukoku is with him. Whether dead or alive, acquisition shouldn't take more than 10 or so seconds (high level porting, paralysis (if needed), Luc removes rune (if needed), leave for next
Blue Moon: The rune is always left in the center of the Blue Moon village. Since it was easy for Neclord to steal it, it should be doubly easy for Luc and Ukoku to steal. I won't even think 5 seconds is needed in the thievery.
Front Gate: See Sovereign, except add Windy. Half runes can't stand up to full runes, so it should be quite easy if Windy is still alive.
Back Gate: I have a video showing how Leknaat can't stop Luc even if she wants to. Luc knows where she lives, so he can easily steal it
Water: Last seen in Chris hands. She didn't master the rune by the end of the gate, so taking it from her should be easy (32 years mastery of his rune and Ukoku by his side)
Viki's Blinking: Probably the hardest to get since the ditz likes to mistakenly port herself about. Good thing there's alway a Viki within the timeline, so getting it before a minute's pass shouldn't impossible.
Sun: Like the Blue Moon, it is left within the center of the castle in which it occupies. Easy to steal.
P.S. Oh yeah, and Luc knows everyone that either owns or knows of these runes. So giving Ukoku knowledge on where to look isn't unbelievable.
Eight-Eight-thirty
Everyone's gathered again, and the telepathic link is opened once again. New info is shared, Ukoku gives info to his team on what he acquired from the other.
Luc uses the Gate rune to mass summon spam (80k+), while adding his own Wincar into the mix. He gives Ukoku another idea and they decide to return to his verse.
While Luc and Ukoku is gone, Cornelia gives one of the "smarter" monster the "Seal of Nerissa", making him pretty much equal to Cornelia, with a little added bonuses. He'll be called Seth.
Cornelia ask Seth to help her glamour up as much people as they can before Ukoku and Luc returns. Glamour, in W.I.T.C.H. verse basically makes anything look likse something else. It could be another person, or an object. Done precisely, my whole team can look like flaura of the verse.
Eight-thiry-Nineth minute
Luc and Ukoku does a final rune raid. A quick one on a rune store, a kidnapping of a rune mistress, and thievery of the Star Dragon.
Final Minute
The link is open up once again, and information is passed around quickly.
Some other demons, by way of Corny and Seth (since they might be glamoured), are equipped with the weapon Fei and Bindt collected.
Cornelia and Seth glamour up anyone not glamoured into whatever I desire (during with whill be decided during battle... nothing that'll be tricksy). Weltall will be an important glamour; being glamoured into one of the main characters. They also make multiple astra drops each.
All the main characters (except Luc) get equipped with a Fury and turtle rune, the tankers with a violence rune, and fire sealing
