TTRPG Encounter Combat Pacing Predictor

Predittore gratuito di ritmo di combattimento D&D.

Quando usarlo

Use before designing the climactic fight of a session — knowing the duration helps you pace narrative beats around it.

Confronto

Encounter difficulty calculators (Kobold+) tell you "is it deadly?" but not "is it long?". This is the time-budget companion.

Enter your values below. Calculations run locally as you type.

Come funziona

Per-turn time = 60 s + level × 10 s, multiplied by the decision-speed selector.

Round estimate is bounded between 2 and 8: more monsters extend the fight, higher level shortens it (better burst damage).

Total = (players + monsters) × rounds × per-turn. Most 5e fights land between 30 and 60 minutes.

Domande frequenti

Is this just for D&D?

Tuned for D&D 5e-style combat but useful for any d20 system. Adjust the decision-speed selector for faster systems (Blades in the Dark, PbtA).

Does it predict difficulty?

No — only duration. Combine with your system's encounter-budget calculator for difficulty.

Why does player decision speed affect the time estimate so much?

Most table time is spent deciding actions rather than rolling dice, so slow or indecisive players can double the real-world minutes for the same number of rounds. Groups that plan turns in advance finish combats far faster.

Why do more monsters slow combat down disproportionately?

Each extra monster adds its own turn, initiative slot, and set of attacks to resolve every round, so total time grows with both monster count and round count. A handful of weak enemies can take longer to run than one tough boss.

Esempio pratico

Input

4 players, level 3, 4 monsters, average decision speed.

Output

4 rounds, ~70 s/turn, ~37 min total.

8 combatants × 4 rounds × 70 sec = 2,240 s ≈ 37 min. Add narration overhead for a real ~45-min fight.

Errori comuni

  • Lair actions and minions inflate per-round time.
  • New player groups run much slower than the "average" preset.
  • Theatre-of-mind play is faster than gridded play.
