Essentially you use the FASRIP Universal Table for task resolution.
When making HeroQuest characters you follow the traditional methods but your ratings are multiplied by 5. So, instead of placing a 17 in your primary Ability, its considered an 85. And instead of having 20 points to customize with, you have 100 points, with no more than 50 going to a single Ability.
When consulting the Universal Table, simply find your Ability's rank. The game will let you know what color result you need.
Its pretty simple.
Masteries are ignored in this version.
