Summary

Researchers introduce DungeonBench, a new benchmark for evaluating AI's tactical reasoning in Dungeons & Dragons combat, designed to test complex rule interactions, resource management, and long-term planning across single encounters and multi-day campaigns. It exposes a complete tactical observation and a list of executable options, challenging frontier language models.

This paper introduces DungeonBench, a novel benchmark specifically designed to assess AI's capacity for complex tactical reasoning within the Dungeons & Dragons combat system. Unlike simpler game benchmarks, DungeonBench incorporates a rich set of rules, including geometry, timing, resources, and objectives, requiring AI to make nuanced decisions. The benchmark offers two tracks: "Encounter" for evaluating local tactical play in single fights, and "Day" for assessing long-term resource management and survivability across linked encounters. The system provides AIs with full tactical observations and a range of executable options, from movement and attacks to spells and resource use. Initial evaluations with frontier language models demonstrate that while these models can perform well in individual encounters, they often struggle with resource budgeting, rest timing, and consistent rule-aware tactical discipline over extended "Day" scenarios. This highlights a significant gap in current AI capabilities for sustained, complex strategic planning.

Why it matters

This benchmark provides a robust tool for evaluating and advancing AI's ability to handle complex, rules-rich environments, which is crucial for developing more sophisticated and adaptable AI agents beyond simple game scenarios. Professionals can use this to understand the current limitations of AI in strategic decision-making and resource allocation.

How to implement this in your domain

  1. 1Explore the benchmark's design principles to inform the development of AI agents for complex simulation environments.
  2. 2Adapt the "Day" track's multi-encounter resource management challenges to test AI policies in business scenarios requiring long-term strategic planning.
  3. 3Analyze the performance of frontier language models on DungeonBench to identify specific weaknesses in tactical reasoning and resource allocation.
  4. 4Integrate similar rules-rich testing methodologies into internal AI development pipelines to ensure robust agent behavior in complex operational settings.
