Step #1 Fill out the monster's stats in these three boxes (Ignore this box; it is addressed in Step 2) ...and then fill in this one. Step #3 Using the table on the right, fill in the expected CR for a creature with the amount of HP you listed in Step #1, then fill in the expected AC for a creature of that CR. Step #4 Using the table on the right, fill in the expected CR for a creature that deals the amount of damage per round you determined in Step #2. Then enter the expected attack bonus of a creature of that CR. Do the same for the expected save DC. Step #5 The formula calculates the CR based on the creature's attack modifier and save DC, then chooses the highest. This final result is your monster's CR!
Damage/Round (Include half-points from odd dice counts)
Step #2
Round # 1
Fill out the monster's MAXIMUM damage output for the first 3 - 6 rounds of combat. (For AoE attacks, assume 2 targets hit) This formula then averages them.
