I have done the CoP mission, unlike the guy below who posted you only have 5 minutes to climb the mountain.
You have 30 minutes to get up the mountain. The stone starts to fade after 5 minutes pass, then every 5 minutes thereafter. It's still difficult though. :D

I got a quest in windy (not shown in log) after i done CoP 3-5 (the one where the characters leave tavnazia and go all over vanadiel, won't say who or where so not to spoil it)
Anyway professor Yoran-Oran wants a "rebirth mirror", but im not 100% sure on names because i use japanese ffxi, and he needs a "rebirth stone" to turn into a "rebirth feature" to fix the mirror. If it's this item here, then the "rebitth stone" is called a Mimeo Stone as in the post by Tribmos.
Obviously you need to complete CoP 3-5 before you can get this quest (not sure if its a quest since its not in quest log)
There definitly a hierarchy of which feather takes how much time.
The stone fades 4 times before it disapears. 0 fades = you get a regain feather (hp/mp/tp) 1 fade = you get a rebirth feather (reraise3) 2 fades = you get revive feather (reraise1) 3 fades = you get fire feather (enfire) 4 fades = you get blaze feather (blaze spikes) 5 fades = mimeo stone disapears and you dont get anything
I tested this, because i got regain feather before anything else, without any fades.
2nd time i got up, with no fades, and it said "You cannot obtain another regain feather." so i waited, and eventually it said "the mimeo stone starts to fade away", and i clicked the cradle again, and i got rebirth feather.
i did this again, and after "you cannot obtain another rebirth feather" i got revive feather
So yes, you can hold all 5 feathers at the same time, after you use a feather (only tested with regain so far) you have to wait 2 hours before using another medicine.
There are 6 pops of luminent, scattered around the mountain. The 1st time that I did it, i went down again, and luminent was up right away. The other times it has taken a long time for it to repop. I suspect either its a random repop time, or that it pops at a certain time during the day, i tested 0:00, but it wasn't up.
Wow, you are pretty quick to discount something you don't know. Since it is common knowledge that you get the regain feather before the first fade, I would say difinitively there is a way up the mountain in one minute, I would also say that because you don't know what it is doesn't make it any less possible.
Judging by the posts, It appears that when you take the "Mimeo Stone" that you get from the Luminent to the top of the Tor (Cradle of Rebirth). You may receive one of the following items. There is no solid evidence to suggest that the reward is time based. My theory at the time of posting is that you receive a random feather after completing (needs testing).
Hmm, this is a nice item, if it's the real effect...auto-collection can be kinda unreliable sometimes, any1 know more about this item? Can it be obtained more than once?
