I FINALLY BEAT SKEITH!!!!

[AZURE-KITE]

Took me one hour. First try, level 30 Kite, BlackRose and Mistral.
Stayed back healing and powering up Blackrose. Then when data drained just went Staccato and killed it after three rounds of it.

...Ran out of resurrects and of Health Drinks midbattle, too >.<

Level up MUCH but VERY MUCH like 10 levels more before you face a Phase, and you can beat it without healing items ^_^

Ah.. I remember, all those years ago, my first battle with Skeith. I got him to about 100 health and then he killed me! That bastard
Totally took him down the second time, though. Yeah. Skeith is my favorite.
