I have a project coming up where I am going to be converting some creatures from DnD 5E to Forbidden Lands so I have been doing some thinking around conversions. Have a look below and let me know what you think: (apologies for the formatting)
Attributes: Max attributes for PCs in 5E is 20, 30 for monsters. Fbl has a max for PCs of 6. Devide 5E by 3.5 to get Fbl attribute.
5E has 6 attributes, Fbl has 4 Attributes
Strength+Constitution/2. = Strength
Dexterity = Agility
Intelligence+Wisdom/2 = Wits
Wisdom+Charisma/2 = Empathy
Animals only have Strength and Agility, Strength is based on HD (see below)
Humanoids have all stats, ignore HP
Monsters Strength is based on HD (see below), they may have all stats if intelligent
For non-humanoids calculate Strength as follows, using size and constitution modifier:
5E Size Hit Dice Conversion
Tiny D4 = HDx.25 ‘. +constitution modifier
Small D6 = HDx.5 ‘. +constitution modifier
Medium D8 = HDx1 ‘. +constitution modifier
Large D10 = HDx1.25 ‘. +constitution modifier
Huge D12 = HDx1.5 +constitution modifier
Gargantuan D20 = HDx2 +constitution modifier
Skill ranks are based on proficiency level -1 (minimum of 1). Adjust any skills for beasts based on current skill scores compared to proficiency level (especially for skills that won’t have the attribute in Fbl).
Skills Deduct attribute modifier, use highest proficiency for skill minus 1.
Strength Athletics == Strength. Might
Dexterity Acrobatics == Agility Move
Dexterity Sleight of Hand ==Agility Sleight of Hand
Dexterity Stealth == Agility Stealth
Intelligence Arcana ==Wits Lore
Intelligence History ==Wits Lore
Intelligence Investigation ==Wits Scouting
Intelligence. Nature ==Wits Survival
Intelligence Religion ==Wits Lore
Wisdom Animal Handling =Empathy Animal Handling
Wisdom Insight ==Wits Insight
Wisdom Medicine ==Empathy Healing
Wisdom Perception ==Wits Scouting
Wisdom Survival ==Wits Survival
Charisma Deception ==Empathy Manipulation
Charisma Intimidation ==Empathy Manipulation
Charisma Performance ==Empathy Performance
Charisma Persuasion ==Empathy Manipulation
Constitution /5 ==Strength Endurance
It can be assumed that for each weapon an NPC has that they have the relevant proficiency, these translate into ranks in Melee or Marksmanship.
Proficiency ==Agility Marksmanship
Proficiency ==Strength Melee
AC-Dex Modifier (if any) -10 = Armour Rating. Some natural armour doesn’t include Dex bonus. Medium Armour Dex Bonus = 2 Max, Heavy Armour = No Dex Bonus.
For humanoids use 5E attack bonus - Strength Modifier as Melee or - Dexterity Modifier as Marksmanship for ranged attacks.
For monsters use individual attacks, subtract 5E Strength bonus from attack bonus, convert 5E Strength score to Fbl stat and add to remaining number. Reduce by 1 for 2 targets, reduce by 2 for all targets in range band. Do not reduce the attack bonus if the creature has Multi-attack (see below).
If the creature has multi-attack then each attack listed targets the relevant number of characters, or a single character multiple times. Increase the attack bonus by the number of attacks listed under multi-attack if you list a monster attack that targets only one character.
Damage is based on the average damage in 5E, 1 to 20 is 1 damage, 21 to 50 is 2 damage, 51+ is 3 damage.
Fear attacks, such as roar, use half Wisdom save as Base Dice
Poison and disease use listed save -10 for potency
