Don't want to say anything negative but I find that
Int Aoe is Much better for aoeing
Probably 2 times as effective as burst crack
Although you waste many posters and mp refreshers, the cast rate of the int aoe is MUCH faster
than Burst Crack (not to mention it takes time to cast Burst Crack over and over again in the action slot
while it takes a shorter amount of time to cast the lvl 70 int aoe, and then a 1/2 second to recast in action slot
You can start aoeing if you want as early as lvl 7x
If you get an alext set +10 (which i advice doing so for aoe since it gives a great amount of hp boost)
I would do 100 stam, xxx int, no str, no dex
Putting more stam is better b/c it takes advantage of your alext set
And then, you can do int rings, with plugs (and i would also advice a def shield)
Also, you could do either a +16 AR suit, or a +28 Def suit (I would not advice +28AR on an alext suit, not that many sellers)
With your AR suit, you'd do significantly more dmg (I'd guess your int aoe would be around 2k-2.3k at first without
SF and GT
Easy Exp and Fast Killing, that's what aoe is all about
Some argue that you can't pvp with this build, but i say you can
It actually depends though
Blades, Knights, Elementors, (Psykeepers without stanology), Bow Jesters and Yoyo Jesters will be easy kills (unless they're like 20 levels above you)
With my gear, I was able to easily take out many people 10 levels above me, and also, if i got swarmed, this int aoe is easy to cast since
you DO NOT have to target a monster

(Note This AOE is only good in Azria, but it will worth getting an Azria ticket. If you aoe in Azria, EASY PROFIT)
