BattleCast encounter test

Lich vs Level 10 Party

A lich should feel terrifying because it can damage the group, reposition, and keep acting between turns. This setup puts that pressure against a larger level 10 party so the fight is dangerous without being just an instant wipe.

Quick DM take

Use this as a high-level spellcaster showcase. The lich has at-will Fireball and Lightning Bolt, plus mechanical legendary actions for teleport damage, Disrupt Life, and Frightening Gaze.

Baseline Monte Carlo result

Across 1,000 simulated battles from this starting layout, Lich had the higher win rate. Lich won 64.1%, Level 10 hero party won 35.9%, draws were 0.0%, and the average fight lasted 14.2 rounds.

What this encounter tests

This encounter tests whether the party can survive repeated save pressure while maintaining damage on a durable caster. The lich is not just a bag of hit points; it keeps changing the fight between hero turns.

The larger six-hero party gives the lich enough targets for AoE without making every run identical.

What to watch in the simulation

Watch the opener and the first legendary cycle. If the lich catches multiple heroes with AoE and then follows up with Disrupt Life, the party can fall behind quickly.

Also watch whether the Paladin and Cleric stabilize the group or get forced into emergency turns before the damage dealers can finish the job.

How to tune it at the table

Tune the lich by changing spacing and party size.

  • Easier: spread the party farther apart or use five heroes with stronger saves.
  • Harder: start the party clustered, or add minions once multi-team support exists.
  • More campaign-ready: treat defeat of the body as only a temporary win if the spirit jar survives.
