In order to more accurately reflect the world presented in Avatar: the Last Airbender, this system recommends the use of a few variant rules, and their use is assumed in the presentation of the system’s unique content. All recommended variant rules can be found at www.d20srd.org. Specific links are also included below.
Class Defense Bonus
The class defense bonus variant rule is ideal for the Avatar: the Last Airbender universe. It encourages the creation of lightly-armored characters who rely more on their skill and agility than heavy armor to carry them through battle. An explanation of the variant can be found by following the above link. It should be emphasized that the class defense bonus does not stack with a character’s armor bonus to AC.
Airbenders gain the AC bonus listed in column A when using this variant. Earthbenders, firebenders, and waterbenders gain the bonus listed in column B.
Armor as Damage Reduction
This variant provides some incentive for characters to invest in armor. Instead of adding a simple armor bonus to AC, under this variant a suit of armor grants a reduced bonus to AC and a small amount of damage reduction. A more detailed explanation of the variant can be found by following the above link.
Vitality and Wound Points
Under this variant, a character’s hit points are replaced by both vitality and wound points. Most types of damage reduce a character’s vitality points, which represent the character’s ability to avoid serious damage from a hit and increase as the character gains levels. Wound points, meanwhile, are reduced only after a characters vitality points are depleted or on a critical hit. When a character’s wound points reach 0, he is disabled and must attempt a DC 15 Fortitude save or fall unconscious and begin dying. A more detailed explanation of the variant can be found by following the above link.
Running games in the Avatar d20 setting requires little adaptation. In most cases, it can be done by simply deciding not to use the variant rule and disregarding information that refers to the rule. If more specific adaptation is required, recommendations are noted in the relevant content’s write-up.
