Defense Value
One of the major differences between standard D20 and the Conan RPG is the substitution of Defense Values and Damage Resistance for Armor Class. This can be calculated using the table below and the following formula:
10 + Base DV + Dex Bonus + Size Modifier = Total DV

Damage Resistance
In most D20 games, Damage Resistance factors in the existence of magic weapons and commonplace Spellcasting, things that are far from common in Hyborea. To compensate, listed Damage Resistance should be divided by 5. If the creature is wearing armor, use that armor’s AC bonus as its DR. Add in Natural Armor bonuses as well.
(DR ÷ 5) + Armor
For example, an OGL creature is listed as have DR 40 and Natural Armor of 7. This would be a DR of 15 in Conan (DR 40 ÷ 5 = 8, +7 = 15).
Many creatures have conditions listed with the DR rating. Ignore anything with a “+” after the slash, such as DR 15/+1, indicating that a +1 or better weapon is required. Any conditions that can be met in the world of Hyborea can be retained, such as DR 20/silver (damage reduction is ineffective against silver weapons) or DR 15/bludgeoning (ignore Dr on damage done by bludgeoning weapons)
Initiative
Add in the Reflex Save to the Initiative since most D20 and OGL games do not include Reflex saves as part of the Initiative Bonus.
Spell-Like Abilities
Many D20 creatures have the ability to cast spells or use spell like abilities. To account for the fact that magic isn't so simple and effortless in the Conan RPG, creatures should have to make Magic Attack Rolls:
Base magic Attack + Charisma Bonus = Magic Attack Bonus
if a caster level is indicated, find that level on the Magic Attack chart (below) and use the values for Good magic Attack. if no caste rlevel is indicated, use the creatures Hit Dice and the information for Poor magic Attack.
For saves against spells and spell-like abilities, use the creatures Magic Attack roll in place of any listed DC.
