How It Works
How the No Escape Doom Growth Simulator Models Your Engine
This simulator samples real draw orders from your deck composition across multiple simulated turns, then tracks when the accumulated Doom crosses the target HP threshold. It is modeling engine timing and draw variance, not one specific hand you already know.
Configure the deck and engine before running the simulation
Enter your current HP and the enemy HP you are trying to execute. Then describe your deck: the Doom-applying cards you are running, how many copies of each, and any relevant powers like Countdown or Oblivion. Set the simulation turn count to match how many turns the fight is likely to last based on act and room type.
The simulator then runs multiple sampled draw orders across that turn count and reports the distribution of Doom totals at each turn. The result shows not just the average outcome but the spread — whether your engine reliably executes by turn 4, or whether it does so only in favorable draw sequences.
- Enter exact copies of each Doom card — one copy of Scourge plays very differently from two.
- Include Countdown and Oblivion if active — they contribute Doom independently of your hand plays.
- Set enemy HP to the actual value you need to hit, not a round number.
- The turn range controls simulation depth: short for elites, longer for bosses.
Draw variance across sampled turn sequences
Each simulation pass randomly orders your deck, then plays through the specified turn count tracking Doom applied per turn and cumulative total. Running many passes produces a distribution showing what percentage of draw sequences reach the execute threshold by each turn. The output reflects genuine draw variance, not just expected-value arithmetic.
The model accounts for the No Escape scaling mechanic: Doom applied by No Escape scales with existing Doom, so early Doom application compounds into higher late-game totals. Cards played earlier in the simulation affect the damage ceiling of cards played later, which is why draw order matters and why the distribution has real variance rather than being a fixed number.
Block, enemy attacks, and power timing are not modeled
The simulator models Doom accumulation only. It does not model whether you survive to the turn where Doom executes, how block interacts with the fight, or whether the enemy has mechanics that remove Doom. It also does not model multi-enemy rooms — Doom is tracked against a single HP target.
If your Doom engine is reliable but you keep dying before it fires, that is a block problem the simulator cannot diagnose. Use the Doom threshold results as a ceiling — the number of turns until execution in a favorable draw — and pair it with your own assessment of whether the deck can survive that long.
