Thief builds

Every player willing to play as a Thief class character must be aware that it is the most challenging class to master in the whole game. In comparison to other classes, the Thief will not make good use of key macros. So a different approach is required.


Thief Mind Breaker, Vicious Cuts Build


This build offers the highest DPS and is well suited both for leveling your character and end game content. It's based on doing damage instantly, rather than DoT.

The whole concept of this build is based on Cunning Tactics skill, which upgrades Vicious Cuts skill to the point of dealing twice as much damage. Both Somersault Kick and Mind Stealer Skills are used as SP regenerators.



Use the Haste buff, then swing Poison Edge, use Cunning Tactics and stab an enemy with Vicious Cuts. In case of running out of SP, use Somersault Kick and Double Slash to regenerate it and go back to using Vicious Cuts when your SP are restored.


Thief Poison DoT Build



This MS2 Thief build is centered around the Poison mechanics. You poison your target and watch their HP drop down to 0 while you avoid attacks. On the negative side of things, it makes you more vulnerable to enemy attacks.



Rotation of skills for this builds looks like this: Cunning Tactics → Poison Edge → Poison Vial, and when it's running out, use Surprise Attack.



That's it in terms of a build for MapleStory 2 Thief. We hope that the guide had helped you to understand the role, positioning, gameplay, and overall characteristic of the most difficult class in MS2. Now, that you have read it, it's time to hop in onto the servers, and poison them enemies to the death!

In the breaks between slashing opponents, killing them slowly with DoT's, and somersault kicking, be sure to check out our other stuff, we've prepared for MapleStory 2 Fans, especially the ultimate MapleStory 2 class guide.
