Rogue-type classes are arguably some of the weakest classes in AQW. The main focus of rogue-type skills are mostly for DoT (Damage over Time), none of which would be as useful as a warrior class's direct attacks and a mage class's skills which help not only the player using it but also players who are fighting along side the player using it. Furthermore, it seems that AQW likes to use the same skills as the rogue class for other and maybe future classes, thus coining the term "rogue-type." If you look at some of the classes a non-member can use in AQW, you'll see that quite a number of them use the same skill set as the rogue class, just with the difference of icons and percentage done by a skill. Take for instance the Leprechaun class. I was so happy that there'd be a new class, and bla, bla, bla... then I saw that they just changed the icons and the percentage done by the skill. Concealed Blade and Patrick's Secret has the same effect. If you're using a barber class, then you'll see that it has the same skill set as rogue and pirate classes; the only difference being the icons.
But with the latter being said, that Rogue-type skills aren't as useful as they might seem to everyone, while ranking up my rogue-type classes--and getting extremely bored in the process--I saw that there's was actually a great way to battle with a near-weak class. It's merely al about being disciplined in using your mana, and finding the right oppurtinity to use which skill at which given point in a fight. Or if you're grinding up on CP or XP, the same applies, too. Remember, this guide applies to the following classes: Rogue, Pirate, Barber and Leprechaun.
So the first skill on your arsenal is the Viper's Kiss (or Irish Blessing on Leprechaun), so this skill is a sort of DoT skill, where you'll autonatically cause a given percentage of a damage, inflicting it on a target, while also "poisoning" it, which lasts for a given amount of time. Next, is Puncture (or Needlepoint on Leprechaun), which increases the damage that you deal on your opponent in a given amount of time by a certain percent. But before we go on further, these two skills are your best friends. Why? Because these are your basic rogue-type class farming tools. If you're ranking up a rogue-type class, then you'll find yourself using these two often. But which of these two should you use first when fighting? Well, some might think that it only is more logical to Puncture first than to Viper Kiss. But no, it's better to Viper Kiss first than to Puncture (or Irish Blessing first then Needlepoint), because you're only given a certain amount of time before the Puncture lasts, and you don't want an automatic attack to come between the succession of your normal attacks, because that is an automatic attack wasted.
So, the third skill is Footwork (or Ceili for Leprechaun). Now this skill increases something and decreases something in the process. So in short, it's sort of like an inverse proportion. Now, I find this skill one of the ones that I don't use too much. It's sort of a skill that you'll want to use when fighting a boss on your own, or maybe just when you're running out of HP. The fourth skill is Concealed Blade (or Patrick's Secret on Leprechaun). This skill is useful only when you're fighting a strong monster or if you're farming solo. What it does is increase your chances of causing a stronger hit on your target in a given amount of turns; so you may or may not get a strong hit each time. The Leprechaun class can do higher damage than the other rogue-type classes.
Just remember these, and you'll make a good rogue. Battle On, non-members! XD
