Deadly Encounter Benchmark

Foundry VTT Module. Help determine the difficulty of combat encounters using this benchmark method. Modeled after Sly Flourish's Lazy DM Prep, and detailed in The Lazy DM's Forge of Foes (https://shop.slyflourish.com/products/forge-of-foes), authored by Teos Abadia, Scott Fitzgerald, and Michael E. Shea.

A Deadly Encounter Benchmark is a guideline that helps determine an encounter's difficulty.

An encounter might be deadly if the sum total of monster challenge ratings is greater than:

• 1/4 of the sum total of character levels, for characters of 1st to 4th level;
• 1/2 of the sum total of character levels, for characters of 5th to 10th level;
• 3/4 of the sum total of character levels, for characters of 11th to 16th level;
• equal to the sum total of character levels, for characters 17th level or higher.

If friendly NPCs join the encounter, their CR values are added to the Deadly Encounter Benchmark.

A deadly encounter means:

• Most characters might lose more than half their hit points.
• Several characters might go unconscious.
• There’s a chance that one or more characters might die.
