Before your next session
Which D&D 5e rules does the encounter calculator use?
Encounter Workbench uses the revised 2024 encounter budgets and monster statistics in SRD 5.2.1. It does not use the 2014 adjusted XP multiplier system or include monsters from paid books.
Can I build an encounter without AI?
Yes. Open the website workbench, sign in or create an account, and choose Manual mode. Select monsters, write your notes, and save or export the encounter yourself.
Does the calculator guarantee a balanced fight?
Difficulty is an estimate. Monster abilities, terrain, party resources, and player choices can change how a fight plays out. Review the stat blocks and scene before running it.
What is included in a PDF or Markdown export?
Your encounter’s party, monster roster, XP budget, scene notes, full monster statistics, source links, and required SRD attribution.
