Opinion Modifiers

What problem does it solve?

This skill provides a structured guide for creating, editing, and reviewing opinion modifier definitions used by Victoria 3. It helps modders ensure consistent key naming, bilateral application, and proper integration with diplomatic actions, events, scripted effects, and on_actions.

Core Features & Use Cases

• Defines a standard structure for opinion modifiers under common/opinion_modifiers/.
• Clarifies how to apply bilateral values, decay, and script-value logic, with examples aligned to the game's modifiers.
• Guides integration with callers such as diplomatic_actions, events, scripted_effects, and on_actions to ensure coherent behavior and maintainability.

Quick Start

Define a new opinion modifier by adding a descriptive key with a constant value in common/opinion_modifiers, and include a decay block only if the modifier should fade.
