Here we will introduce some example of the best skilling combos for Battle of the Immortals each class. From that, you may learn some useful skills and to enhance your character.

First i advise you to get full +4 skill set, weps +4 skill and the latest rings.(if ur at least 70 get the bracelets 2)
Note : Check my latest reply to check out the armors I think suit nicely for a good skilling session.

Go to an area with mobs that have a lot of hp(so u can combo like 12 Hits to kill the selected mob) and that you get 0 exp or around that value in order to just skill instead of skilling and lvling(the reason for that can be explained by people who are low ranked).

I tested some combinations of skills based on their cast/cool time and ive reached some interesting fast combos:

Blader : Assault(lv.9)>>> Impact Stab (lv.9) >>> Double Slash (lv.9)
My first Skill in less than 3 minute experience.

Force Blader : Force Assault(lv.9) >>> Impact Stab(lv.9)>>> Force Slash(lv.9)
Still working but that combo will do the trick

Force Shielder: Shield Charge(guess thats the name, lvl.9)>>>Impact Stab(lv.9)>>>Flash Draw(lv.9, can be another skill)Note: Use the Warrior Combo 2^^.

Warrior: Assault Skill(If thats the name, known by charge) (Lvl.9) >>> Impact Stab (Lvl.9) >>> Rising Shot (Lvl.9)

Note: Works for FS Aswell.

Force Archer : Freezing Arrow ( Lvl.9) >>> Aqua Arrow(Lvl.9) (Works fine those 2 in combo.)

Wizard : Do Freeze (Lvl .9) >>> Burning Hand (Lvl.9) >> (This 1 can be put out but good when u need to hit far) Magic Arrow (Lvl.9)

That's all.Hope this helps. Have a good time in Cabal online...
