Custom AI
Custom AI is a custom combat intelligence system that makes monsters behave in a significantly more dynamic and reactive way during combat. Instead of following fixed attack patterns, monsters with Expanded AI evaluate the situation in real time and respond accordingly.
What changes in combat
Monsters with Expanded AI can:
- React to player tactics: for example, a monster may try to avoid or counter specific skills, reposition in response to area-of-effect threats, or break out of defensive setups.
- Adapt to the party's composition: different player classes may draw different responses from the same monster. Healing classes, ranged attackers, and frontline fighters may each be handled differently.
- Support and coordinate with allies: monsters can heal, buff, or assist nearby allied monsters during a fight, creating more coordinated group encounters.
- Change behavior based on health: many monsters shift to a different combat phase when they drop below certain HP thresholds, changing their skill usage or aggression level mid-fight.
- Scale with difficulty: on Heroic and Mythic difficulty, monsters become more aggressive, use their skills more precisely, and react faster than on Normal.
Where it is applied
Expanded AI is currently active on monsters in open-world encounters and instance content. The system is designed to grow over time: future updates will extend it to pets and summons, including companions from classes such as Beast Master Hunters.
