The D6 System is a role-playing game system published by West End Games (WEG) and licensees. While the system is primarily intended for pen-and-paper role-playing games, variations of the system have also been used in live action role-playing games and miniature battle games. The system is named after the 6-sided die, which is used in every roll required by the system.

Attributes and skills

Characters in the D6 System are defined by attributes and skills. Attributes represent the raw ability of a character in a certain area. Most D6 System games utilize anywhere from six to eight attributes, though these can vary greatly in number and name by the game in question. Acumen, Intellect, Knowledge, Perception, Presence and Technical are examples of mental attributes; Agility, Coordination, Mechanical, Physique, Reflexes and Strength are examples of physical ones. Skills are the trained abilities of the character and are associated with a specific attribute (e.g., driving, acrobatics, and climbing might be skills based on the Reflexes attribute). Each attribute and the skills under it are rated in values of Dice and Pips; Dice equal the number of dice rolled and Pips equal a one or two point bonus added to the roll to determine the result. The more dice and pips in the rating the better the character is at that skill or attribute. A character with a Strength rating of 4D+2 is stronger than a character with a Strength rating of 3D+1, for example.

Actions and resolution

Character actions are resolved by making dice rolls against a difficulty number. There are two types of difficulties, standard and opposed. To perform a standard difficulty action, the gamemaster calls for the player to roll the dice for a certain attribute or skill. The value of each die is totalled and the pips are added to the die roll to get a total. This total along with any GM or system imposed modifiers is compared against a target difficulty number. To perform an opposed roll action, the two parties involved (usually the player and a gamemaster controlled character) both roll their appropriate skills dice, total them and any modifiers and compare the results. If the first party's roll is higher than that of the second, he wins the contest and the rest of the result is resolved. If the second party equals or exceeds his opponent's roll, then the second party wins the contest.

The Wild Die

One of the dice rolled for each skill or attribute check or for damage is considered to be the "wild die", and is treated somewhat differently than the other dice. If a six is rolled on the wild die, then the die "explodes" allowing the roll of an additional wild die. The resulting sixes are added to the total, and the roll continues as long as the player continues to roll sixes on the wild die. If a one is rolled on the wild die during the initial roll (not after a six is rolled), and another one is rolled in the second roll, a critical failure or complication occurs, usually with bad results for the character. If a number other than one is rolled after an initial roll of one, then that die, and the one with the highest number are subtracted from the roll's total. Use of the wild die tends to make the game feel more cinematic.

Improving Rolls

In order to increase their characters' effectiveness, players may spend character points and fate points. The exact number of character points that may be spent is limited by the amount possessed by the character, and the situation that they are used in, with two being the typical limit. Each character point spent adds an extra wild die to one skill or attribute roll. A roll of one has no negative effect with wild dice generated from character points. Alternately, a character may spend one fate point on an action. Characters have fewer fate points, but the expenditure of them doubles the amount of dice rolled on an action.

Variant resolution systems

Most D6 System game use the resolution system described above, which is sometimes called The D6 Classic System, though some variants exist. In one variant, The Legend System, instead of adding the die totals up, the dice showing 3, 4, 5 or 6 are each counted as a success. Use of a skill requires rolling a certain number of such successes. Pips are not used in the Legend System. This variation of the system was referred to, in jest, as "The D6 variant for the mathematically challenged" on WEG's own discussion forum. The Legend System has been utilized in the Hercules & Xena Roleplaying Game and the DC Universe Roleplaying Game. Other variants, such as those featured in the Star Wars Live Action Adventure Game and the Star Wars Miniatures Battles game, involve rolling a single six sided die and adding the result to a skill or attribute. This total is then compared to a difficulty number, as with the other variants.
