How to Prep a Combat Encounter Quickly as a Game Master

Evergreen guide for Sixsmith Games products and the people who use them.

Sixsmith Games·April 19, 2026

    Fast encounter prep does not mean lazy encounter prep. It means knowing which pieces of information are load-bearing during a fight and preparing exactly those things before the session starts.

    What you actually need before combat begins

    Most game masters over-prepare some things and under-prepare others. The things that matter during combat:

  • Token placement and starting positions
  • Initiative order or how you will establish it
  • Hit points for every creature in the fight
  • Conditions or abilities that affect the first turn
  • Terrain features that will change positioning
  • Everything else can be improvised at the table without slowing the encounter down.

    The fastest path from nothing to ready

    Start with the map. Even a rough sketch or a gridded area is enough to establish positioning and make token placement meaningful. A blank grid is better than no map at all.

    Then set up your creatures. Know the HP and any notable abilities upfront. You do not need the full stat block memorized — you need the number that matters when the fighter swings and the one ability that will surprise the players.

    How a combat tool shortens prep time

    Virtual Combat Simulator reduces prep time by keeping token placement, initiative, and combat state in one place. Instead of building the encounter across a map tool, an initiative spreadsheet, and a scratch pad, you set up once and the tool handles tracking during the fight.

    For a game master running sessions regularly, that consistency pays off quickly. Less setup per session, less mid-combat context-switching, more time focused on running the story.
