What are the A-grade weapons in Heterocycle? In the sci-fi action role-playing game "Heterocycle," the weapon equipment known as "Arc Disks" is not only the cornerstone of character attributes, but the selection and combination of weapons are also one of the cores for players to improve combat efficiency and conquer various challenges. Compared to the rarity and difficulty of obtaining S-grade weapons, A-grade weapons, which have excellent performance and are relatively easy to obtain, become the main equipment for most players in the mid-game. This issue will take you to a deeper understanding of the most representative types of A-grade weapons in the game and provide precise pairing solutions for different combat scenarios to achieve maximum combat power output.
The Arc Disk is essentially a next-generation armament interface fueled by emotional energy and instinctive impulses, converting weapon characteristics into the character's inherent abilities through neural links. It not only directly boosts attack/defense/health panel values but can also activate combat buffs such as damage stacking, energy recovery, and attribute conversion when certain conditions are met. At the same time, there are strict compatibility restrictions on the Arc Disk, requiring confirmation before equipping that the character's attribute tag is either emotion-based or instinct-based.
I. "Headless Iron Driver" - Core of the Emotion-Based Speed Attack Style
Adaptation Target: Emotion-based speed attackers (such as Nightingale, Crimson Sky) Base Buff: +16% Attack (constantly effective) Core Special Effect "Flame Resonance": After using an orbital slash (↑+attack button) or extreme orbit thrust (↓+attack button), it triggers a [Blazing Mark] lasting 20 seconds. During the mark's duration, all normal attack damage increases by 20%, with this effect stackable up to 2 layers (i.e., a theoretical increase of 40%). This is very suitable for boss battles and elite monster confrontations. When facing high HP targets, by continuously releasing orbital→extreme orbit→normal attack cycles, within 4 seconds, you can achieve: Orbital Slash (activates 1 layer of the mark) → Extreme Orbit Thrust (activates 2 layers of the mark) → Normal Attack Combo (enjoying a 40% damage increase). Actual tests show a 34.7% increase in single-target DPS, making it the optimal solution during burst windows.
II. "Eclipse" - Core of the Instinct-Based Sustain Style
Adaptation Target: Instinct-based clearers (such as Dark Eclipse, Eternal Night) Base Buff: +24% Attack (exclusive to instinct-based characters) Core Special Effect "Light Devouring Echo": When activating the arc skill (character-specific skill), it creates an [Eclipse Field] with a radius of 15 meters, lasting for 40 seconds. Each time a character inside the field kills an enemy, they immediately recover 2 points of field essence (ultimate energy), with a maximum of 5 triggers per field. In densely packed monster areas like abyssal tower climbing, opening the field and combining it with AOE skills enables a perpetual cycle of "kill→energy recovery→ultimate skill." Upon activation, the sky turns dark red, increasing shadow attribute damage by 10% and marking hidden treasure chest locations. Prioritize killing elite monsters to trigger high energy recovery, avoiding wasting kill counts on minor enemies.
III. "Frameless" - An Adaptive Survival Fortress for Instinct-Based Characters.
Adaptation Target: Instinct-based tanks/half-tanks (such as Rock, Steel Body) Dynamic Buff Mechanism Twin Pact: Health > 50% → +36% Attack (Offensive Form) Health ≤ 50% → +36% Defense (Defensive Form) High health at the start enhances offensive capabilities, assisting in quick clearing; after taking damage down to half health, it automatically switches to a defensive stance, forming a "Health Roller Coaster" tactic when paired with a healer. Offensive phase (100%-51% health) → Taking damage below 50% → Healer raises health above 51% → Resets to offensive form. This cycle allows the character to have both burst and survival, significantly increasing effectiveness in prolonged battles.
IV. "Zero Synergy" - The Control Engine for Emotion-Based Characters.
+18% Attack, emotion-based characters deal 45% increased damage to frozen/paralyzed enemies. Recommended Pairing: Frost Speaker + Ice Arc Skill, forming a hard control burst chain; V. "Entropy Core Fission" - Catalyst for Instinct-Based Anomaly Flow. +22% Defense, burning/poison damage from instinct-based characters is increased by 30%, and DoT can crit, core component of poison-fire builds, combined with Eclipse for sustained damage bursts within the field. Peak output control → apply anomalies → dual-rail skill burst, theoretically increasing damage by 119% within 12 seconds; Energy operation - 5 kills in the Eclipse Field = 10 points of essence recovered (ultimate energy typically costs 8-10 points); Priority principle - avoid forcing cross-attribute assembly due to high stats (e.g., emotion-based character using Eclipse), as it would render special effects completely ineffective. Resource倾斜策略优先将突破材料投入主C弧盘（如无首铁驭/日蚀），防御型弧盘（无画框）升至2阶即可。特效触发阈值无首铁驭需精确计算20秒buff期，建议战斗前预设连招序列；日蚀领域注意站位集中化。A级弧盘虽然并不算顶级装备，但通过科学搭配可发挥90%的S级武器效能。牢记属性克制与队伍职能分工，就能在资源有限的开荒期实现战力最大化。
That concludes the content about what A-grade weapons are available in Heterocycle. Always remember that the core of Arc Disk pairing lies in attribute synergy rather than simply stacking numbers. A reasonable combination and timely adjustments for different scenarios are key to maximizing combat power output.
