Should have call this thread "How not to do the Cavern of Transcendance Trial" and stuck it in the Player Guides section.
I'd have to say that the team started off great but turn to a shambles when we started stealthing it. I'd freely admit since I was the leader that it's mostly my fault. The last time I did this was with my controller who I respeced especally for this trial to have invis and recall at lvl 14.
Sure we had a lvl 12 scrapper with grant invis, but bless his little noobish socks off he needing constant propting to do anything for most of the part (btw Neutron it was you who told me too invite him 
) I'd have to say in hindsight I would have fought more mobs given how we did well to start with. But someone (me) mentioned re-spawning even though he hadn't confirmed this and didn't know to what level 
The next hour consisted of much shouting and confusion due to 3 of the obilisks being closly guarded and so invis would be needed to activate them but we had to make sure our invis granter had a safe one, of course it didn't help that I didn't know where everyone was since they ran off to find they're own obilisks. But after a some capslocked shouts of shut up and few mad dashes we got the obilisks lit with less than 2 mins on the clock.
As Neutron said many temp powers were used including the confusing nectar I saved from pocket D. And to everyone's surprise we did it.
I'd just like to thank all the team for sticking in there, i've seen better orginised team's fall to pieces and fail many a time. But your determination won in the end and i'll probably smile everytime I see my Transcendant badge. 
Now @Eskimo-Spy

Hey you went one better, i finished the trial literally under the foot of the AV
I responce to the inviting of the "noob" eskimo, how can u turn a low lvl down when he stares into your eyes with that noobling glint of hope & says "PLLLLLLLLLLLLLLLZ?"
Eskimo decided hmmm lets have a go with some low lvled guys, so we got ourselves a low level team. BAD IDEA.
Sure clearing out the main hall of the cavern was easy, but then came the obelisks we didn want 2 fight 2 each 1 in turn so we decided we'll get invis from a low lvl guy it was all fine and dandy at first 4 peeps got their obelisks, then communication broke down , peeps started dieing, and general chat system was maxed out. arranging ourselves at the obelisks eventually took 1 hour <:/. That left us with exactly 4 mins 2 kill the av, it was the quickest av kill ive ever seen, 2 peeps pulled out their croatoa temps about 3 pulling out wolf temp powers from striga. OVERWHELMED him. Though the funniest thing of all was the remaining time limit...
38 seconds.
Every1 on our team has decided to put each other on ignore and never speak to each other again it was that horrendous...
