Convert 4e monsters/encounters to 5e
Convert 4e monsters/encounters to 5e monsters/encounters
1. I'm assuming a level 3 5e PC is about the same as a Level 1 4e PC.
2. After that, it assumes 1 5e level and 1 4e level are about the same.
So an adventure for level 15 characters in 4e would be roughly a level 17 adventure in 5e.
A "hard" encounter (L+4) in 4e roughly maps to a "deadly" 5e encounter of "corresponding" (ie, 2 levels higher, 4 instead of 5) characters.
Epic balancing (Level 21+ and CR 21+) is loosy-goosey however.
L1-19: CR = Level+2
L20+: CR = Level/2 + 12
L1-3: CR = Level
L4-19: CR = Level/2+1.5
L20-30: CR = Level-8
L31+: CR = Level/2+7
L1: CR = 1/4
L2: CR = 1/2
L3-15: CR = Level/3, round down
L16-25: CR = (Level-15)/2 + 5
L25-30: CR = Level-15
L 1: CR 0
L 2-3: CR 1/8
L 3-9: CR 1/4
L 10-14: CR 1/2
L 15-19: CR 1
L 20-24: CR 2
L 25-30: CR 3
This assumes you rebuild the monsters using 5e math. It attempts to make a hard 4e L X encounter for 5 characters be a "deadly" encounter for a party of 4 L X+2 5e characters.
An attack round should deal (CR+1)*6 damage if >= 1. Work out a 3 round attack combo, that should be average damage per round. Consider AOEs to hit 2 targets.
Stats should work unchanged. For each attack, pick an appropriate stat. Add proficiency for ATK vs AC, and add 8 for DC.
For AC, subtract the 4e level, then add 1/3 of the 5e CR.
For HP, use (2+CR)*15 as a baseline if CR >=1.
For monsters with CR <=1, use CR*12 damage and CR*45 HP roughly.
Give Elites and Solos proficiency in saves. Solos, add on legendary actions.
