In this guide, we will tell you how to play with this weapon. After knowing the gameplay, you can use this weapon in actual combat.

Speaking of the Furnace Gun, it is a weapon that can be used for both melee and ranged attacks in the game. The ranged attack comes from its charging skill, through which various forms of attacks can be released. It can be said that the charging skill is its main means of output. This is how to use the Furnace Gun. After understanding this, let's move on to the effective builds for the Furnace Gun. Currently, there are multiple effective builds for the Furnace Gun.
Firstly, we will look at the first one, known as the Flame Build. Under this build, the weapon options include choosing one from Fiendish Furnace Heart, Flame Dragon Engine, Celadon Furnace Gun, Vortex Furnace Rocket, and Meteoric Iron Furnace Gun. Among these, the Flame Dragon Engine and Vortex Furnace Rocket have the highest priority. After selecting the weapon, next, you need to carry armor.

For armor, you can choose one from Skyburner, Redstone Mage Robe, Guardian White Robe, and Legendary Mage Robe. The highest priority among these armors is Skyburner, followed by Guardian White Robe. After equipping the armor, it's time for treasures. For this build, the core legendary treasure is the Fire Dragon Head, which is a must-have. Additionally, you can pair it with Formless Blade, Glasses, and Nai Lu's Seal. After equipping the legendary treasures, it's time for cursed treasures.
For cursed treasures, you need to equip the Pocket Watch, Crown, and Rusty Blade. After equipping those, it's time for epic treasures. Among the epic treasures, the Fire Dragon Family is definitely a must-have, followed by a series of treasures that can increase flame damage. Finally, you can add red or blue runes. After equipping, the final blue treasures should also prioritize flame type treasures, followed by red and blue rune treasures. Once equipped, this build is complete.

After completing this build, the small skills used during charging in actual combat will receive a significant bonus to flame damage, which is very powerful and can deal high flame damage to enemies. After completing this build, let's move on to the second build. This second build is known as the Slash Build, which is also primarily a red-based build but plays completely differently from the Flame Build. This build relies on rune slashes for damage, not flames.
For a build that relies on slashes for damage, the weapon options include Pressurized Furnace Three Styles, Demon Spine, Demon Exterminator Spear, King's Claw, and Blast Claw. Among these, Demon Spine and King's Claw have the highest priority. For armor, you can choose one from Sacred Warrior's Pride, Beast Face Chainmail, Wandering Robe, and Crimson Rune Armor. Among these, Sacred Warrior's Pride has the highest priority. After completing the armor setup, it's time for treasures.

For this build, the legendary treasures needed are Formless Blade, Glasses, Hunter's Mark, and Judgment Hourglass. Among these, the Hourglass is the core and must be equipped. Next are the cursed treasures, which include the Demon Sword, Rusty Blade, Cloak, and Annihilation Claw. The Demon Sword is the core and must be obtained. After equipping the cursed treasures, it's time for epic treasures. These treasures do not have specific requirements, as long as they can add red runes. Generally, such treasures have the effect of increasing critical hits and rune damage, so you can just equip them fully. After equipping, it's time for the blue treasures, which follow the same principle as the epic treasures. After equipping, this second build is also complete.
