It's quite easy to get lvlcap in the close beta for all those over lvl3x it's just a few hours
For this u have to know where ur training at and which mob ur killing to lvlup fast.
If ur able to beat some BabaJaga's then just follow the instructions to lvlup fast.
But first u have to install A-Speeder () and start it before u login to cabal-online.
The most impertant thing is to finish all ur quests at ur current lvl, after doing this just go to the training-spots wich are listet below.
--------------------------------------
If u are at lvl3x and finished all ur quests at ur current lvl, go to the BabaJaga's in Bloody Ice
set the gamespeed to 2x that should be enough to kill them before they attack u.
u can farm exp by the BabaJaga's untill u can kill them with less than 4 skills (if ur a wizard) or if u dont need much time to kill them (blader/swordsman).
--------------------------------------
Between lvl31-39 u can go into the Skeleton-Mine-Dungeon if u have the D-Class Skeleton-Mine-Cards.
--------------------------------------
If ur at lvl4x and finished all ur quests at ur current lvl, go to the Ape's in Bloody Ice
set the gamespeed to 2x while hunting Ape's thats enough to kill them before they attack u.
here u can farm exp untill the Ape's are to week for ya (if u can kill the Ape Zombie's without problems for example)
--------------------------------------
If u are able to beat the Ape zombies just forget them and go to the Shades, they are very good to farm exp. After finishing all quests at ur current lvl go to the Shades in Bloody Ice.
set the gamespeed to 2x but take care of ur char if ur a wizard, they can do much of dmg. Like u can see in the Picture above (click at it to view) u just have to stay at the red circle and wait until a shade spawns. In this spot there are just 2 shades, if ur standing at this spot the shades will spawn in front and behind u so u dont have to move just wait, kill the shade in front of u, then turn back and kill the other one behind u.
U will notice that u gonna lvlup very fast D
If u have another Training-spots that u prefer or other tips to lvlup just post it
Happy grinding
