No third-party addon required.\n\n> **Related skills:** **resource-pattern** for the `Resource` data containers, **component-system** for the component node pattern, **event-bus** for cross-system ability events, **state-machine** for caster states (e.g. casting/stunned), **hud-system** for cooldown UI.\n\n---\n\n## 1. Architecture overview\n\nAn ability system in Godot 4.x is built from three collaborating layers:\n\n- **Data layer — `Ability` (Resource):** Each ability is a `Resource` subclass with exported fields (`ability_name`, `cost`, `cooldown`, `cast_time`) and two methods: `can_activate(caster) -> bool` to validate preconditions, and `activate(caster) -> void` to execute the effect. Storing abilities as Resources lets designers create and balance them in the Godot editor without touching code.\n\n- **Behaviour layer — `AbilityComponent` (Node):** A single node added to any entity that should use abilities. It holds the granted ability set, enforces cost/cooldown, and drives the `Ability.activate()` call. Four signals keep the rest of the game informed without coupling: `ability_activated(ability)`, `ability_failed(ability, reason)`, `cooldown_started(ability, duration)`, and `cooldown_finished(ability)`. Grant new abilities at runtime with `grant(ability)` and trigger them with `try_activate(ability_name)`.\n\n- **Effects layer — stat modifiers, buffs/debuffs, and gameplay tags:** Abilities can read from and write to a caster's `StatSet` (a Resource that owns a dictionary of named `StatModifier` entries) to apply temporary or permanent stat changes. A `GameplayTagContainer` node (a child of the caster) gates activation — for example, a \"stunned\" tag can prevent any ability from firing. These three deep-dives are covered in the reference documents:\n  - [Stat modifiers and StatSet](references/stat-modifiers.md)\n  - [Gameplay tags and conditions](references/tags-and-conditions.md)\n  - [HUD binding for cooldowns and resource bars](references/ui-binding.md)\n\n**Core rule:** *Data in Resources, behavior in the component, communication via signals.*\n\nThis separation means an `Ability` resource carries no Node references and can be safely duplicated, saved, and loaded as any other Godot Resource. The `AbilityComponent` owns runtime state (cooldown timers, active ability set), keeping `Ability` resources stateless and reusable across multiple casters simultaneously.\n\n---\n\n## 2.
