In the Double Helix game, the positioning and skill characteristics of different characters are the standards for determining weapon selection priorities. For new players, to achieve better performance in the game, it is necessary to deeply understand the core mechanisms of each character. Therefore, how to choose weapons in the Double Helix also needs to start from the characteristics of the characters, such as whether they focus on output, survival, or support. Then, combined with specific combat scenarios, carefully select weapon types that can maximize the advantages of the characters.
For core damage-dealing characters, it is recommended to prioritize high-burst ranged weapons or area-of-effect melee weapons. This recommendation is made because these types of weapons can greatly enhance the character's damage output. When choosing, one should focus on weapons that can increase critical hit rate, skill multipliers, or come with special effects, so that the character's damage output can be maximized. For example, the Crimson Assault Rifle, this ranged weapon has a unique effect: it can increase final damage based on the remaining ammunition in the magazine, up to 50%.

This characteristic makes it capable of bursting out more powerful damage during combat, especially when the magazine's ammunition gradually decreases. It is very suitable for ranged characters who rely on skills or basic attacks for damage, like Rain and Aria. Using it, they can gain a significant advantage in combat. Another example is the Punishment's Blaze, a melee weapon whose effect is to stack continuous damage and healing effects upon attacking. This is very suitable for melee characters with high attack speed, like Belenika. Using it, she not only excels in damage output but also enhances her sustainability through its healing effect.

For survival and counter-attack type characters, high-defense or life-steal melee weapons and control-type ranged weapons are more suitable. This is because the main task of these characters is to survive in combat and counter-attack using their own abilities. Therefore, to strengthen their survival, choosing weapons with life-steal, shield, or control effects can effectively extend combat duration. The Wise Defense is a melee weapon very suitable for close-range tank characters. Its effect is +50% defense, and it can reduce the target's shield when an extra effect is triggered by an attack.

For a close-range tank character like Flora, this weapon can greatly enhance her survival in combat, allowing her to withstand enemy attacks while also dealing effective blows. The Wave Whisperer, as a ranged weapon, has an effect of +62.5% critical damage and increased damage with more ammunition. For remote damage dealers who rely on critical hits, like Truffle, it is a good choice, enabling them to deal damage to enemies while ensuring a certain level of survivability.

The weapon selection for support and auxiliary roles should primarily focus on functional ranged weapons and team-benefit melee weapons. The main responsibility of these characters is to provide various supportive effects to the team. Therefore, priority should be given to weapons that can offer healing, damage amplification, or control effects, to better assist teammates. The Blazing Gun's Feast is a remote weapon suitable for fire-attribute support characters. Its effect is to increase skill and ranged weapon damage after a fire-attribute character dodges, up to 25.2%.

For a fire-attribute support character like Truffle, this weapon allows her to bring higher damage benefits to the team while dodging enemy attacks. The Hopeful Harvest is a melee weapon whose effect is reduced ultimate skill damage but increased attack speed. For support characters who rely on ultimate skills, like Psyche, this weapon allows her to release skills more flexibly in combat, providing more assistance to the team. In actual gameplay, players also need to master the weapon switching mechanism.

During combat, weapon switching can switch between melee and ranged. For instance, when facing distant enemies, one can first use a ranged weapon for consumption, then switch to a melee weapon for burst output when the enemy gets closer. At the same time, attention should be paid to the synergy between weapon attributes and character skills. When choosing a weapon, priority should be given to those that match the character's attributes, such as fire, wind, etc., or skill mechanisms like critical hits, life steal, etc. For example, a fire-attribute character paired with the Blazing Gun's Feast can fully utilize its effect of increasing output after dodging.
In summary, selecting weapons in the Double Helix still requires considering many factors. The most important thing for new players is to choose weapons based on the role's position and combat needs. During the game, it is essential to prioritize reinforcing the equipment of core damage-dealing characters, while also not neglecting survival and support.
