D&D Simplex is a simplified version of Dungeons and Dragons 4e that incorporates elements of Gamma World and other lighter rules games to make the game run smoother and faster. Instead of the traditional ability scores, characters are Strong, Quick, Smart, or a combination thereof.

Building a Character

Building a character in D&D Simplex consists of 4 simple steps:

1. Choose class: Choose one class from the race list. You gain its traits up to your starting level.

2. Choose archetype: Choose one archetype from the archetype list. You gain its traits up to your starting level.

3. Choose skills: You gain 12 points to spend on your six skills (each point increases a skill by 1, up to a maximum of 6). Choose a skill to train (in addition to the skills your race and class train; these skills must be different). Trained skills gain a +4 bonus.

4. Choose equipment: You gain one armor, one weapon, and one artifact of your level or lower.

Character Statistics

Each character has all of the following:

Health The representation of how much punishment your character can take before they collapse, measured in hit points. You gain the base health determined by your class and archetype, plus a bonus determined by your class, archetype, and level.
Health = Class Health + Archetype Health + Level x (Class Health Bonus + Archetype Health Bonus)
Bloodied Value Half your health. Some traits and powers are triggered when you are bloodied, and your second wind heals you your bloodied value.
Bloodied Value = Health / 2 (rounded down)
Defense Represented by Fortitude, Reflex, and Will, these show how hard you are to hit effectively.
Defense = Class Defense + Archetype Defense + Level + Bonus
Initiative How quick your character is ready to act in a fight.
Initiative = Level + Bonus
Speed How quickly you move in battle.
Speed = 6 + Bonus
Skill How proficient you are at certain tasks. The base rank in a skill is bought by the player out of a pool of 12 points with a max rank of 6 in any skill. The six available skills are listed in the Skills section.
Skill = Bought Ranks + Level + Bonus
