The four combat styles
Neon Abyss 2 rebuilds the weapon system from scratch. Veewo and Kepler Ghost describe four broad directions: melee (bats and sabres), plants, summons (commanding dragon-like creatures) and conventional firearms. The armoury runs past a hundred weapons, and many carry a resource tag — Hatchmon-type, Crystal-type, Wisp-type, Key-type and so on — that links them to the matching resource.
| Style | How it plays | Stats it wants | Examples | For you if… |
|---|---|---|---|---|
| Melee (bat / sabre) | Get in close and trade positioning for burst | Damage Bonus, Attack Speed, Crit Chance | Taomu, RITUAL | You like the original's melee rhythm and can dodge at zero range |
| Plants | Place or summon offensive plants for sustained damage | Projectile Size, Range, Luck | Whatever the run drops | You prefer area control and a "set up the board" feel |
| Summons (dragons / Hatchmon-type) | Creatures fight for you; you and your pets work as a pair | Hatchmon count, Damage Bonus | Noxmare, Topspin, RITUAL | You want to pair with the Hatchmon system |
| Firearms | Conventional bullet-hell shooting with wildly different projectile types | Attack Speed, Range, Crit Chance | Raptor, Sunder, 9th Color | You want the run-and-gun fundamentals — lowest barrier |
Veewo's framing for all of this is "unlimited item synergies": the weapon is only the base, and the build comes from item stacking. When you pick a style, first work out which stats it scales off, then check where your item pool and your Faith line are pushing you.
Aligning a build around a resource
Many weapons are less about their base numbers and more about which resource you can reliably supply:
- Hatchmon axis — Hatchmon-type weapons plus mass hatching at the Temple of Agapeism and the Adorable Companion Fate Card. Topspin (a tennis ball that bounces between Hatchmon and grows faster with each hit) and Noxmare (poison stacking to 9 for a detonation; Hatchmon attacks add poison too) are the flagships.
- Crystal axis — Crystal-type weapons plus Artefacts that raise your crystal container cap. 9th Color (every 9th shot becomes an empowered attack) and Icelume (auto-follow-up ice beam, spending crystals to spawn cores that duplicate your attacks).
- Wisp axis — Wisp-type weapons plus Tenebrism to generate wisp containers. Sunder is the clearest example: crit chance rises while you hold blue Wisps.
- Bomb / Key axis — Raptor's homing missile count scales with your bomb stock, so pair it with Consumerism and snowball by buying bombs. Ghostprint spawns a clone that copies your attacks for every key you hold, which is close to a straight DPS doubling.
Ten weapons worth knowing
Media-tested picks with their unlock conditions, usable as a priority list for what to grab:
| Weapon | Type | Unlock | Core mechanic | Pair with |
|---|---|---|---|---|
| Noxmare | Hatchmon-type | Default | Stacking poison; 9 stacks detonates for heavy damage, comes with its own Hatchmon | Any summon build |
| 9th Color | Crystal-type | Default | Every 9th shot becomes empowered (rainbow beam / homing); spending crystals charges it further | Crystal axis; save crystals before a boss |
| Raptor | Firearm | Default | Fast fire rate, releases homing missiles after a few shots, missile count scales with bombs held | Nik / James (start with bombs), Consumerism |
| Sunder | Wisp-type | Hold 3 blue Wisps in one run | Very high fire rate and range; crit chance rises while holding Wisps | Wisp axis, Tenebrism |
| Topspin | Hatchmon-linked | Hatch 10 eggs in one run | Ball grows and speeds up with each hit, and bounces off Hatchmon | Agapeism, lots of Hatchmon |
| Icelume | Crystal-type | Clear a run with any Crystal-type weapon | Auto-follow-up ice beam on hit; spends crystals to spawn cores duplicating your attacks | Crystal container Artefacts |
| Taomu | Melee / jump-type | Default | Extra jump; charged attack fires homing talismans and leaves a fire trail | Jump-tag Artefacts, melee builds |
| Ghostprint | Key-type | Default | Each key spawns a clone that copies your attacks | Consumerism buying keys, key-start Agents |
| RITUAL | Hatchmon-type | Clear a run with any Hatchmon-type weapon | Every third hit marks enemies; each Hatchmon fires a bone-spike ring at marked targets | Agapeism, Hatchmon army |
| Celody | Crystal-type | Collect 20 jump-tag Artefacts in total | Hold to spin a star field for melee, or fire the bodies as projectiles with unlimited range | Jump builds, hybrid ranged/melee |
Fixed vs dynamic affixes
The headline system of 1.0 (Veewo's own line: "Affix your weapons, Agents!"). Every weapon carries two affix layers:
- Fixed Affixes — innate to the weapon. The same weapon always rolls the same fixed affixes; this is the weapon's identity.
- Dynamic Affixes — randomly rolled, covering direct damage bonuses, resource bonuses and special mechanics. Higher weapon level means both a higher chance of rolling them and stronger rolls.
Two weapons with the same name can therefore be wildly different in power. Don't vaporize an early weapon just because its rolls are bad — swapping to another copy of the same weapon can turn it around instantly. Conversely, only invest Reforge resources into a high-level base.
Affix stats: the six dimensions
A January 2026 update consolidated weapon stats into six values, and every affix acts on one of them:
| Stat | Effect | Stacking advice | Priority |
|---|---|---|---|
| Damage Bonus | Raw output increase | Universal — works on every build and returns the most reliably | ★★★★★ |
| Attack Speed | Sets your damage rhythm and speeds up proc-based weapons (9th Color, Taomu) | Prioritise on fire-rate weapons | ★★★★ |
| Crit Chance | Chance to crit | Multiplies with Wisp-axis and Sunder-style crit interactions | ★★★★ |
| Projectile Range | How far shots travel | Low value for melee and tight-room builds; high value in open boss arenas | ★★★ |
| Projectile Size | Coverage width and a more forgiving hitbox | Core for plant builds and size-scaling item builds | ★★★ |
| Luck | Veewo's patch notes do not spell out the exact effect | Take it with spare rolls; don't sacrifice damage affixes for it | ★★ |
TIP
The top three (Damage, Attack Speed, Crit) decide your DPS floor — keep high-rarity rolls in those. Range and Size change feel and forgiveness. Luck's numbers are unpublished; hitting a fixed training dummy is the most direct way to compare affix value.
Rarity tiers
Weapons and affixes share four tiers:
| Tier | Affix strength | Role |
|---|---|---|
| Common | Baseline | Early filler |
| Rare | Enhanced | Mid-game workhorse |
| Epic | Strong | Worth Tempering extra affixes onto |
| Legendary | Strongest | The chase target for a run |
Veewo hasn't published a full breakdown of where high-rarity weapons drop. The general pattern: deeper floors, shops and reward rooms roll higher rarity, and higher weapon level makes high affix rolls more likely.
Reforging and Tempering
Timeline: the affix system first appeared in beta on 2026-02-05 (SteamDB patch 21791898), then shipped properly on 2026-03-05 as the fourth major update, Weapon Reforge, alongside the new boss Aphrodite.
Core mechanics:
- Weapon level-up choices expanded: alongside the existing Artefact path there is now a Temper option.
- Tempering adds a specified affix to a weapon, making the growth path much more controllable.
- Because dynamic affix strength scales with weapon level, reforging is fundamentally "rerolling affixes on a high-level base".
Cost-benefit decisions
| Your situation | Do this | Why |
|---|---|---|
| Low weapon level, bad affixes | Neither — just level it | Low level can't roll strong affixes; Tempering is wasted |
| High level, usable base affixes | Temper the affix you want | Locks in value and pushes toward Epic / Legendary |
| Main weapon not maxed | Vaporize junk weapons into Soul Shards and level first | Level is the foundation every affix scales from |
| Same-name weapon with terrible affixes but high level | Swap to another copy and reroll the dynamic layer | Fixed affixes are identical; you're only gambling the dynamic layer |
| Decent base, tight on resources | Defer to the next floor's shop or Soul room | In-run resources appreciate as you descend |
Known bug
Veewo confirmed a fix for a bug where the Temple of Artisanism could wipe golden affix values when a weapon was downgraded. If you're running an Artisanism build, screenshot your weapon before you start cutting.
Artefact Extraction
Artefact Extraction is the permanent, cross-run growth layer: consume or destroy an Artefact to buy a permanent bonus to one of the six stats. It trades "an item you can use right now" for "long-term save progression", which puts it in direct conflict with your current run's power.
Two rule-changing Relics flip that calculation:
- Philosopher's Stone — Extraction instead grants a random Artefact, turning a flat stat trade into a gacha pull. With a warehouse full of surplus Artefacts, that's free pulls.
- Empty Cup — Weapons no longer level up, but upgrade slots remain. It's the inverse trade: current-run growth for long-term planning.
Vaporizing and Soul Shards
Vaporizing converts a weapon into a large amount of Soul Shards, which you feed to a weapon to level it quickly. It's one of the game's core loops: pick up weapons → vaporize the ones you don't want → feed your main weapon. Hold the interact key next to a weapon to do it.
Two efficient routines:
- Soul Shard room farming — prioritise the Soul Shard room each floor, buy every affordable weapon from the shop and vaporize them all to max out one weapon fast.
- Junk discipline — vaporize anything off-archetype unless it's Legendary or tied to an unlock. Don't let "maybe I'll use this later" items slow down your build.
Faith is a separate system: it unlocks special rooms where you can shop, recruit Hatchmon or gamble. No official material states that vaporizing produces Faith directly — the two connect only indirectly, through Relics that change how Extraction and Vaporizing behave.
Reforge or vaporize?
| Situation | Advice |
|---|---|
| Same-name weapon, terrible affixes, already high level | Swap to another copy and reroll rather than vaporizing |
| Main weapon not maxed | Vaporize junk for Shards; skip Tempering until level is done |
| High-level base with usable affixes | Temper the affix you want and push for Legendary |
| Artefact warehouse overflowing, long-term stats the priority | Send them to Extraction for permanent bonuses |
| After picking up Philosopher's Stone or similar | Re-evaluate Extraction and Vaporizing value before acting |
| Weapon gated behind an unlock (Sunder, Topspin) | Unlock the compendium entry first, or you'll regrind the unlock |
WARNING
Both vaporizing and extraction are irreversible. The order is always: confirm it has no unlock value → confirm it isn't a Legendary base for your archetype → only then vaporize or extract.
