FFX2

many people have asked this so heres how:

in ch.5 in bevelle sloisters (pm me on what these are)
you'll meet a black elemental on cloister 20.
upon defeating it there is a chest containing, speed bracer, sprint shoes, aaaand CAT NIP.

**to DEAFEAT blak elemental.
if you have dark knight just charon it and its an instant overkill. if not....

level up to at least 65.
go in with beserkers. equip defense up accessories.
Attack with your best moves (ie. hurt, mad rush....)
i would use 2 beserkers,1 warrior.
use your warrior to use armour break and lower its defense on first turn.
attack and/or heal using beserkers.

then on warriors second turn cast as many lunar/star curtains as possible.

this is a tricky battle to do without dark knight simply because the elemental has such high defense and will cast ultima on you very quickly. if you dont have dark knight i would suggest back tracking through bevelle and getting it.doing it the way without dark knight is extreamly hard and literally becoems 70% luck 30% tactics. it all depends on how the elemental attacks you.
