Combo is a unique AoE ( area of effect) skill of Blade Knights and Blade Masters can perform.
It multiplies your damage depending on your strenght agility and energy for the skill damage!
For those who wants to know about combo, i made this guide just for you guys!
But before you can do combo, you must do Marlon's Ring of Honor and Dark Stone quest.
There are many types of combinations for the combo. But first I'm going to make shortcuts of the skills for you to follow easier!
WS = weapon skill
TS = twisting slash
DS = death stab
RB = rageful blow
FIRST - WS, TS, DS
SECOND - WS, TS, RB
THIRD - WS, RB, TS
FOURTH - WS, RB, DS
FIFTH - WS, DS, TS
SIXTH - WS, DS, RB
Basically the last 2 skills in combo can be any 2 orb skills (except Swell), but the first skill must always start with weapon skill. The two most powerful forms are the first form and the second/fourth form.
The FIRST form being the most powerful because of the speed that it is executed at. If done properly, the first form can be executed 2-3 times per second. The downside is that you must keep your mouse hovered over your target while you execute the 3 skills or else it will not work. I find doing this form is effective against opponents that stay still while using attacks that involve range, such as SMs, Elves and combo-less BKs who stay still while attacking with skills. If you're fighting a bk who uses this form alot, you might have a hard time keeping your right mouse button down, your cursor on the target and continuously switch skills because of the constant moving around.
The SECOND form is commonly used by BKs who have knowledge of how to do combo but cannot execute the first form fast enough because they lag alot or still cannot handle the first form. This form is slower and doesn't require you to have your cursor over the target continuously like the First form. This combo form will execute at a slightly longer range than the first form. This form is very effective when you lag alot and cant switch keys fast enough during battle.
The FOURTH form is basically a slower variation of the first form.
NOW, HOW TO EXECUTE THEM!
Make sure you have the skills you're using, hotkey 1-3. In this example, I will be doing the Second form so I'll hotkey weapon skill to 1, rageful blow to 2 and twisting slash to 3.
First, hold down your right mouse button over your opponent so your bk is executing the weapon skill. Hold it for as long as you want. When you're ready, press 2. That will execute Rageful Blow after the weapon skill. When you see the ground beginning to crack from the skill, immediately press 3 to execute twisting slash. When twisting is executed at the end and combo is successful, you should see a large blue explosion and a loud cracking sound.
If you feel the second form is too slow, let's move onto the first form. Hotkey weapon skill to 1, twisting slash to 2 and death stab to 3.
Again, start at skill 1 and hold down your right mouse button on your opponent. Hold it for a few seconds if you want, then when you're ready, immediately press 2 then 3. Then time between 2 and 3 has to be in an instant, you cannot delay or else combo will fail. The result is the same, blue explosion and cracking sound. The best way to practice this form is by asking someone who got a full stat Blade Master/Blade Knight if you can practice against them OR practice against the Kalima boss, Kundun
