How Basic Attack Modifiers Work in Mewgenics

Basic attacks in Mewgenics are deceptively simple on the surface: they cost no mana, every cat has exactly one, and they generally can't be used more than once per turn without bonus attacks. But underneath that simplicity is one of the deepest modifier systems in the game. Dozens of passives, items, mutations, and set bonuses can alter what your basic attack does, how it targets, what it inflicts on hit, and even replace it entirely with something new.

Understanding how basic attack modifiers interact with each other — and with each class's unique basic action — is essential for evaluating builds, identifying synergies during level-up drafts, and making the most of your equipment. This guide breaks down every category of basic attack modifier in Mewgenics and how they work.

What Counts as a Basic Attack?

Before diving into modifiers, it's important to establish what "basic attack" actually means in Mewgenics' combat system. Every cat has exactly one basic attack, determined by their equipped collar (class). Equipping a collar replaces the default Collarless basic attack with a class-specific one.

The starting class basic attacks are:

Collarless — A standard melee attack.

Fighter — Melee Attack. Deals damage to an adjacent unit equal to the user's Strength. Straightforward and scales directly with STR.

Hunter — Lobbed Shot. A ranged attack that deals damage based on Dexterity. Uniquely, Lobbed Shot arcs over obstacles and allied units (no line of sight required), but cannot target units within one tile of the Hunter. This minimum range dead zone is the Hunter's defining weakness.

Mage — Magic Dart. A ranged magical attack. By default it has shorter range and lower damage than the Hunter's Lobbed Shot, but it fires in a straight line and requires line of sight.

Tank — A melee attack. Tanks use their basic attack to chip away at enemies and apply pressure at close range.

Druid — Sing. This is the most unusual basic attack in the game. Sing is a non-damaging area-of-effect ability that heals and buffs allies in a two-tile radius of the target. The Druid wiki page explicitly states that despite being called a "basic action" in some ability descriptions, Sing is mechanically a "basic attack" and applies all basic attack modifiers the user has. This distinction is critical — it means abilities that add on-hit effects to basic attacks will apply through Sing's AoE, which can create extremely powerful (or extremely problematic) interactions.

Butcher — Cleave. A melee attack that also spawns food on the ground, which can be consumed for healing.

Monk — Monks can switch between melee and ranged stances, with their basic attack changing accordingly. This gives them unique flexibility with basic attack modifiers since the same modifier can apply to two different attack types depending on stance.

The key rule is: any ability, passive, or item that says "your basic attack" applies to whatever basic action your cat currently has equipped, regardless of class. This means the same modifier can behave very differently on a Hunter (ranged, arcing) versus a Fighter (melee, adjacent) versus a Druid (AoE, non-damaging at base).

Categories of Basic Attack Modifiers

Basic attack modifiers fall into five categories: full replacements, on-hit effect additions, accuracy and damage modifiers, bonus attacks and refreshes, and range or targeting changes. Some abilities and items span multiple categories.

Full Replacements

These modifiers completely replace your basic attack with a different action. They change the fundamental nature of how your cat attacks at base.

Paw Missile (Mage passive) — Replaces Magic Dart with a basic attack version of Magic Missile. The new attack has infinite range, ignores obstacles, and never misses. Its damage scales with Intelligence rather than the default stat. The trade-off is lower base damage (3 at base INT versus Magic Dart's standard), but the quality-of-life upgrade of guaranteed accuracy and obstacle-ignoring shots makes it one of the Mage's best passives. Because it's still classified as a "basic attack," all other basic attack modifiers still apply on top of it.

Versatile Vocalist (Druid passive) — Replaces the Druid's Sing with a damaging version that deals magic damage and applies debuffs to enemies instead of healing and buffing allies. This solves the Druid's core problem: without Versatile Vocalist, basic attack modifiers that add damage or debuffs will apply through Sing's AoE, which heals enemies and allies alike — meaning harmful on-hit effects could be applied to your own team. Versatile Vocalist restricts the damage and debuffs to enemies only, making it safe to stack basic attack modifiers on a Druid.

Druid Transformation Abilities — Several Druid active abilities transform the cat into an animal form for the rest of the battle, replacing their basic attack with a new form-specific one. If you use multiple transformations in the same battle, you get the combined stat boosts of all forms, but your basic attack becomes that of the most recent transformation.

Nurse Set Bonus (items) — Changes your basic attack to the Holy element and allows it to heal allies. This item set effectively turns any class into a support hybrid, and it stacks with whatever class basic attack you already have. The Medic Hat specifically makes your basic attack heal allies at the cost of -1 damage.

On-Hit Effect Additions

These are the most common type of basic attack modifier. They add an extra effect that triggers every time your basic attack lands, without changing the attack itself.

Animal Control (Hunter passive) — Your basic attack forces the target unit to immediately attack an enemy within their range. This is a forced-action effect — you're commanding the target to take an action on your turn. The upgraded version also allows your basic attack to heal allies. This modifier is particularly devastating against bosses that are positioned near their own minions, since a single Lobbed Shot can cascade into additional damage.

Purifier (Cleric passive) — Your basic attack removes debuffs from allies. This turns the Cleric's basic action into a cleanse tool, which is significant because it costs no mana and doesn't use up a spell slot.

Chain Knockback (passive) — Your basic attack gains +1 Knockback, and units you knock back will knock back other units they collide with. The upgraded version increases all knockback by 2 and adds +1 extra damage. This can create chain reactions where a single basic attack sends multiple enemies flying.

Thorn Arrows (Hunter passive) — Adds Thorns to your basic attack.

Thief's Hood (legendary item, Thief class) — Your basic attacks inflict Bleed. This is an item-based modifier rather than a passive ability, showing that equipment can add on-hit effects just like passives.

Item-based on-hit modifiers — Several items add effects to your basic attack. Examples from the item database include: basic attack creates bramble tiles, basic attack inflicts Poison 2, basic attack spawns tall grass, basic attack inflicts Slow with a chance to Freeze, and basic attack emits a sparkle. These stack with passive ability modifiers.

The interaction between on-hit additions and the Druid's Sing deserves special attention. Since Sing hits an area (the target tile plus everything within two tiles), an on-hit modifier like "basic attack inflicts Poison" would apply Poison to every unit in that area — including allies. This is why the Druid wiki warns that items and mutations granting debuffs through basic attacks can be "detrimental to the Druid's support capabilities" and recommends either avoiding those modifiers or using Versatile Vocalist to restrict effects to enemies.

Accuracy and Damage Modifiers

These change how often your basic attack hits or how much damage it deals, without fundamentally altering the attack's behavior.

Bullseye (Hunter passive) — Your ranged attacks never miss, and you gain +25% critical hit chance. The upgraded version also grants +1 Luck Up each time you crit during battle, creating a snowball effect. This is one of the strongest basic attack modifiers in the game because it eliminates the miss chance on abilities like Heavy Shot and Arrow Flurry as well — but its most consistent value is making every single Lobbed Shot a guaranteed hit with high crit potential.

Hunter Class Set Bonus — +50% crit chance while standing in tall grass. This applies to basic attacks and everything else, making terrain positioning a core part of the Hunter's damage output.

Items: Monocle — Physical attacks can't miss. Similar to Bullseye but available to any class through equipment.

Items: Training Band — +20% crit chance. Applies to basic attacks and all other attacks.

Items: weapon with +10% Crit Chance — Some weapons add crit chance specifically to basic attacks.

Bonus Attacks and Refreshes

These modifiers let you use your basic attack additional times in a turn, effectively multiplying all your other basic attack modifiers.

Arrowsmith and Craft Arrow (Hunter actives) — Grant a Bonus Attack, allowing the Hunter to fire an additional Lobbed Shot. Since all basic attack modifiers apply to each shot, a bonus attack with Bullseye and Animal Control means two guaranteed-hit forced-action triggers in a single turn.

Fighter's Helm (legendary item) — 15% chance to refresh your basic attack, movement, weapon, and trinket actions when you get a kill. This can chain into additional basic attacks in a single turn.

Second Wind (Collarless active, 8 mana) — Refreshes your basic attack, movement, weapon, and trinket actions. Once per battle (or once per turn with the Unrestricted passive).

Parasitic item — "You can use your basic attack and movement action an extra time each turn." Powerful but comes with the Parasite and Cursed tags, along with the penalty of disabling all your passives during battle.

Item-based: 10% Bonus Attack — Some items grant a flat percentage chance to gain a Bonus Attack when using your basic attack.

Range and Targeting Modifiers

These change where or how far your basic attack can reach.

Hunter's Monocle (legendary item) — +2 range on all attacks, including basic attack. Extends the Hunter's already-long Lobbed Shot range even further.

Sniper (Hunter passive) — Likely extends range or modifies targeting behavior for ranged basic attacks.

Long Tail (cat physical trait) — Extends ability range, which applies to basic attacks that are ranged.

How Modifiers Stack

Multiple basic attack modifiers stack with each other. This is where the build depth of Mewgenics really opens up. A Hunter with Bullseye (never miss, +25% crit), Animal Control (force target to attack an enemy), Thorn Arrows (add Thorns), and Arrowsmith (bonus attack) fires two guaranteed-hit, crit-chance-boosted Lobbed Shots per turn, each applying Thorns and forcing the target to attack their own allies.

The stacking rules are straightforward:

Ability-based modifiers stack with item-based modifiers. A passive that adds Bleed and an item that adds Poison will both apply on every basic attack.

On-hit effects from different sources all trigger. There's no limit to how many on-hit effects can apply from a single basic attack.

Full replacements override each other. If you have Paw Missile and then equip the Nurse set, the most recent replacement takes priority (though this may vary — verify in-game).

Bonus attacks apply all modifiers. A bonus attack granted by Arrowsmith or an item applies every on-hit effect, accuracy modifier, and forced-action trigger that applies to the base attack.

The Druid Exception

The Druid's Sing basic action is the single most important edge case in the basic attack modifier system, and it deserves emphasis. The wiki explicitly confirms that Sing is a "basic attack" for the purposes of all modifiers, despite being called a "basic action" in some tooltips.

This means: if a Druid has an item that makes their basic attack inflict Poison, Sing will apply Poison to every unit in its two-tile AoE — including allies. If the Druid has Animal Control, every unit hit by Sing will be forced to immediately attack an enemy in range, potentially creating chaos across the entire battlefield.

The recommended approaches to managing this are: use Versatile Vocalist to restrict harmful effects to enemies, avoid equipping items with harmful basic attack modifiers on Druids, or lean into it with Druid transformation abilities that replace Sing with a targeted damaging attack instead.

Building Around Basic Attack Modifiers

When evaluating a build, ask these questions about your basic attack modifier options:

Does my class benefit from basic attack modifiers? Hunters and Fighters get the most value because their basic attacks are already strong damage actions. Mages benefit if they have Paw Missile. Druids need Versatile Vocalist or a transformation before stacking harmful modifiers. Clerics and Tanks can turn their basic attacks into utility tools with the right modifiers.

Am I getting bonus attacks? Every bonus attack multiplies the value of every modifier you have. If you're stacking on-hit effects, a single source of bonus attacks dramatically increases your output.

Do my modifiers conflict? An item that adds ally healing to your basic attack and a passive that adds enemy damage are fine together on most classes, but can be chaotic on a Druid. Check for AoE interactions.

Am I using an accuracy modifier? On Hunters specifically, the value of every other basic attack modifier is gated by whether the attack actually lands. Bullseye or Monocle should be the foundation before stacking other effects.

Basic attack modifiers are one of the quieter systems in Mewgenics — they don't show up in flashy spell descriptions or dramatic AoE animations. But they're always working, every turn, for free. The difference between a cat with zero basic attack modifiers and a cat with three or four stacked on top of each other is often the difference between a clean run and a wipe.
