I am sure most of you already have it capped already, but for the ones who don't, this is a trick I researched on and proven that it works, can get up to 40 eva in 120 seconds.

First off you will need the following 3 temp items:
Sprinter's Drink
Fanatic's Powder
Fanatic's Drink

the first two I got from default when I get visitant status, not sure if you need to get merit abyssite for it to be default, but if you don't, check cruor prospector for it; as for Fanatic's Drink, go to any Bastion Prefect and you can buy that for 150 resistance credits.

when you have all 3 things ready, get to Abyssea - Attohwa, flux 7, walk South East to east and get to chigoe camp.

Here is what you do:
Make sure that the chigoes are all popped
wear any dmg reduction gear that you have, or magic.
Pop the Sprinter's drink
Run and pull the ENTIRE chigoe camp till you reach the other side
give a bit leeway for yourself to pop the fanatic's, which one doesn't matter, and let the magic begin.
when close to 50 ish second, pop the other, and then repeat till desire eva is reach.

Enjoy!
