Heavy Gunners are arguably one of highest damage dealing Maplestory 2 Class currently. Heavy Gunner is viable for any dungeon and clearing content is pretty fun because of the explosive skills. They have medium mobility and no shields make Heavy Gunner a character prone to getting one shot (Heavy Gunners have a heal, but what’s a heal worth if you’re dead from 1 hit). Even though Heavy Gunner has bad survivability, it is still a relatively easy class to play, making it an excellent beginner’s pick. This Maplestory 2 Heavy Gunner Build Guide will teach you how to steamroll content like never before.

Heavy Gunner Attribute Points
Heavy Gunners can be built two ways: Critical Rate or Dexterity. I personally recommend placing all your points into Dexterity because it makes your overall DPS consistent. Crit builds work well too but having bad luck can cost you a lot, especially in Hard Dungeons where max respawn is only 5 times. Do note that attribute point resets are free, so experiment until you find the best Heavy Gunner attribute point setup for yourself. For example if you have a lot of Critical Damage on gear it is usually better to go full Critical Rate in AP’s than Dex.

Heavy Gunner Builds
Heavy Gunner Blast Charge Kit/Electric Blast Build
Beginner friendly, level 50-60 build for end-game content, world bosses and dungeons.
This MS2 Heavy Gunner Build is based around the Electric Blast aka the laser skill. It’s a really strong build that does really well in boss fights because of the huge amounts of damage it can do. By upgrading the Advanced Pulse Weapons node to 10 you’ll have a lot of increased damage on Electric Blast along with Blast Charge Kit. Note that Rocket Launcher is not needed but does boost your DPS by quite a bit. Level 8 Rocket Launcher should be sufficient for any content if your build is Skill Point hungry.
Shoot Lock-On and after that use Electric Blast 3 times (you can also queue them up, use 2 before a boss encounter and then use the 3rd stack for more damage). Use Rocket Launcher as well if you’ve got the SP, whenever you run out of SP make sure to use Reload, it’s an excellent skill that quickly replenishes your SP.
Heavy Gunner Bullet Spray Build
Bullet Spray is an awesome Skill that does a lot of damage at any level of content and paired with the other high damage skills it makes a killer combo.
The Bullet Spray MS2 Heavy Gunner build is quite similar to the first one, but instead of focusing on Blast Charge Kit you’ll be using Bullet Spray more often. This build is excellent for any type of content as it has AoE and Single Target therefore only thing that limits you with this build are Skill Points, if you’re leveling you won’t have enough Skill Points for this.
The skill rotation for this build is simple: Lock On (once)->Rocket Launcher(once)->Magnetic Bomb(once)->Electric Blast(max charge)->Bullet Spray (hold down). Only use Bullet Spray once your other Skills are on cooldown. Whenever they come off cooldown make sure to cycle through them again. Don’t forget that you can also charge the Electric Blast for more damage.
Bullet Spray in this build can be used by itself, you can spam it on it’s own if you want to, but if you want to do the highest damage possible (very key intensive tho) then do the cycles mentioned above.
Heavy Gunner Lazy AFK Macro Build
The Lazy AFK Heavy Gunner is more of a meme build but it can be great for people that want to watch shows while grinding “boring” parts of MS2.
This Heavy Gunner Build utilizes Rockets, Missiles, M-Bomb and Electric Blast to deal a lot of AoE damage in order to speed clear through the content. The build itself is viable and you can use it while leveling to 50~60 before you unlock enough Skill Points to run one of the builds mentioned above.
All you need for this build is to configure your Macro. Put Rocket Launcher, Homing Missiles, M-Bomb and Electric Blast on a Macro and just hold a button while these spells decimate everything in your path. Doing Bosses with this is sub-optimal because you can’t just afk those, most of boss fights involve dodging and using mobility skills but for leveling this build is more than fine.
