Dungeons and Dragons (D&D) is one of the most popular tabletop role-playing games. But there are not a lot of tools nor data to answer questions about party optimization, resource management, combat difficulty, etc. Enter: FIREBALL, a dataset of 25,000 unique combat sessions. This dataset logs individual actions and character information from 25,000 unique sessions, giving a lot of information to leverage for answering a variety of questions.

This group will be answering the question "How many rounds should a combat take?" This tool could help dungeon masters who are crafting encounters and are wanting to ensure their big perfect monster survives long enough to be a threat, or to prevent a large combat from becoming a boring slog.
