What problem does it solve? Generic CR tables in D&D 5e do not reflect how a specific party actually performs at the table. This Skill replaces guesswork with empirical combat intelligence by building per-PC and party-wide combat profiles from character sheets and real session data, so encounter difficulty is calibrated to observed dice rolls, damage, and tactics rather than assumptions. ## Core Features & Use Cases - PC Combat Profiles: Creates per-character documents with theoretical sustained/nova DPR, effective HP, defensive thresholds, resource economy, counter profiles, and an append-only session combat log. - Party Combat Profile: Compiles individual profiles into combined DPR, synergy matrices, weakness maps, and an empirically derived Effective CR Band that the prep-encounter skill reads for difficulty calibration. - Character Sheet Conversion: Converts PDF character sheets into canonical agent-readable markdown at wiki/system/players/{pc-slug}-sheet.md. - Use Case: After a session with combat is ingested, run this Skill to append observed damage and hit-rate data to each PC's profile, recalculate observed averages, and flag the party profile for recompilation before the next encounter is designed. ## Quick Start Update the combat profiles for all PCs using the combat data from session 4 and recompile the party combat profile.
