# Hero Perks

> Passive bonuses that unlock based on the hero you're playing and the abilities you pick.

The **hero perk** system grants additional passive abilities or bonus skills to heroes based on thematic alignment with the abilities they've selected (or simply by virtue of playing a particular hero). It gives each hero a sense of identity even in a fully open ability draft.

## How it works

When you open the skill picker there is a **Perks** checkbox. Enabling it filters the list to show only abilities that are relevant to your hero's perk categories, making it easier to build around a theme.

`hero_perks.kv` maps each hero to one or more **perk categories** or **specific ability names**. If your picked abilities match those categories, the associated perk passives unlock automatically.

### Perk categories

Perks are grouped into thematic categories. A hero can be tied to one category, multiple categories, or a specific ability name (using `|` as a separator). Examples:

Heroes with an empty perk entry (like Batrider, Warlock, or Pudge) do not have a perk category filter — any ability is equally valid for them.

## The Chen creep perk

`perks.kv` defines a special sub-system for Chen. When Chen's perk is active, his Holy Persuasion converts creeps that retain specific abilities. The list of abilities Chen can grant to converted creeps includes:

* Enchantress Untouchable
* Faceless Void Time Lock
* Life Stealer Feast
* Luna Lunar Blessing / Moon Glaive
* Anti-Mage Mana Break
* Heartstopper Aura
* Axe Counter Helix
* Phantom Assassin Coup de Grace
* Juggernaut Blade Dance
* Ursa Fury Swipes
* Sven Great Cleave
* Vengefulspirit Command Aura
* and many more

Legion Commander shares the same perk definition as Chen, meaning her Duel can also convert creeps with the same ability pool when the perk is active.

## Gender classification

`perks.kv` also includes a gender map (`male` / `female`) used by Queen of Pain's perk, which has different effects depending on the gender of nearby heroes.
