Poison Knight is a very distinctive build (BD) in the game "Gale Knight", with its core gameplay built around "stacking poison damage". Not only does it deal explosive damage, but it also has extremely strong survivability. New players who are just starting out may not be familiar with the Poison Knight of Gale Knight and might find all kinds of skills, relics, and synergy mechanisms confusing. It's worth trying out the Poison Knight, as it boasts high health, high shields, and is very durable, making it suitable for beginners to steadily progress.

Starting Out:
It's recommended to start with the Knight class, paired with the Poison Knight's main weapon, "Oberon" (also known as Aolong). Upon entering the game, the first thing to do is to go to the shop and buy the Aolong Longsword and Lifebuoy relic. The Aolong skill is simple to operate, requiring only a long press of the skill button to automatically release the skill and clear enemies. It comes with area damage and high-frequency attacks, which can easily achieve large-scale poisoning when combined with poison damage in the mid-game. The role of the Lifebuoy is to provide two shield slots automatically at each BOSS level, which, combined with the Knight's high durability, makes the entire progression much more stable. At the beginner stage, using Aolong + Lifebuoy and holding down the skill button can basically allow you to "mindlessly" clear stages.

Core:
The core of building a Poison Knight lies in the order of unlocking skills and the precise pairing of relics. First, enter the game carrying only the "Spikes of Hatred" and try to successfully modify it through the black market. If successful, this skill will transform into a four-star form, which is the prerequisite for unlocking "Activation Dart" later. After a successful modification, restart the game, carry the Activation Dart, and clear a few small monsters to complete the poisoning effect. Then exit the game again and unlock "Toxic Spread." Repeat the above steps, carrying the Activation Dart and Toxic Spread together to accumulate 10,000 poison damage, and you can also unlock the "Neurotoxin" skill along the way. It's important to note that although Toxic Spread is a passively released skill, its output efficiency in clearing small monsters is not very high. Therefore, it's recommended to prioritize fighting BOSSes to quickly accumulate poison damage values.

The next step is to unlock the two core skills, "Toxic Cloud" and "Poison Coating," with the unlocking of "Toxic Cloud" being more complex, requiring a one-time use of the four-star Toxic Cloud skill to deal 500 poison damage. It's recommended to first unlock damage-boosting relics such as "Lizard Skewer," "Flow Fragment," and "Moldy Mushroom" to enhance the skill's power. In terms of strategy, you can choose to gather monsters and stack poison or fight the BOSS "Greed" in levels 1-3, due to its high health, which makes it easy to accumulate high damage numbers. After unlocking "Poison Coating," you can gradually assemble the complete Poison Knight skill set, including: Activation Dart, Toxic Spread, Toxic Cloud, Poison Coating, Poison Blade, Poison Gas Explosion, Neurotoxin, and Overload, with a 6-poison, 4-magic, and 2-curse combination, which basically covers the core needs of the Poison Knight.

Relics:
The strength of the Poison Knight also depends on the synergy of relics. The recommended core synergy is the "Toad Set," which includes the "Little Toad" and "Toad Fluid" relics. When combined, they greatly increase the efficiency of poisoning, especially when linked with the Knight's high skill frequency, forming a continuous and seamless coverage of poison damage. If this set is further strengthened by adding the "Mystic Egg," it forms the "Big Toad Set," which, when triggered, achieves even stronger poison damage stacking. Adding the "Corrosive Skeleton" and combining it with the "Big Toad Set" forms the "Toad Sage Set," considered one of the most stable core builds for the Poison Knight, offering high output, strong fault tolerance, and quick formation.

Advanced:
The "Ultimate Poison Knight BD," also known as the "Rotten Eye Lich Set," is composed of the "Elixir of Immortality" and "Corrosive Skeleton," combined with the "Toad Sage," creating a poison damage system that takes the damage to the next level. With an extremely high frequency of applying poison, the output is like a gushing spring, making it an essential combination for the Poison Knight to tackle high-difficulty challenges. On this foundation, you can also choose the "Chimera Set" or the "Trickster God Set" as reinforcement options. The Chimera requires "Flow Fragment + Lizard Skewer" to stably boost skill poison damage, while the Trickster God's combination is more adventurous, requiring "Steel Boots" to prevent operational reversals, suitable for players who enjoy extreme operations.

"Black Death Poison Knight" is centered around the "Thirsty Vine + Corrosive Skeleton + Strange Celestial Mask" forming the "Black Death Set," plus the "Mystic Egg" and "Elixir of Immortality" to complete the build. This set relies more on the passive area poisoning of the "Rotten Eye Lich" compared to the Toad flow, so it's crucial to unlock and configure this relic in advance; otherwise, the Mystic Egg will prevent the skill from being used, leading to a significant drop in output.

This concludes the introduction on how to play the Poison Knight in Gale Knight. The Poison Knight is a powerful BD with a low entry barrier and high damage growth, allowing beginners to get started without much thought, while veterans can delve deeper into refining it. If you have completed the basic build of the Poison Knight, you can try honing your skills in various high-difficulty chapters or experiment with building more extreme poison damage variants. There is no "one-size-fits-all" solution; as long as the build is reasonable and the operation is in place, it will work well.
