CR Calculator

CR Calculator

The tool allows you to take a monster and modify its value, increasing or decreasing its lethality by modifying its attacks, Hit Points, AC or other attributes and Actions. You may wish to read the Dungeon Master's Guide section on monster creation, (pages 273 - 283). You can click on the table to the right to fill in values for a given and adjust to taste. You can hover over the individual labels for a short description of how each attribute contributes to a monster's CR. You can also hover over each feature description to see how that feature affects the calculations.

Instructions (How to use it)

Monster Scale CR

Bestiary

Each creature's Entry in the Bestiary has a scale button next to its challenge rating. Click on the button and slide the scale up or down to increase or decrease its threat. This feature is best for small changes (up to +/- 4) in effective CR, taking a CR 1/4 monster to CR 20 isn't advised. It's fun. Perhaps even funny. But not advised.
