- Wild Cards are player characters or special NPCs or monsters that are tougher than regular people (the Extras).
- Wild Cards get to roll an extra die called the Wild Die.
- Each Wild Card has the use of Bennies.
Wild Cards also get to roll a Wild Die for every action they take. The Wild Die is a d6 and if Sir Nicholas is fighting another knight, he gets to roll a d8 for Fighting and a d6 Wild Die and keep the best value. Since Savage Worlds is an open-roll system, if either die scores the highest number (an 8 on a d8 or a 6 on a d6, called an "Ace"), Charley gets to re-roll and add to the value, increasing his chance of a success.
Wild Cards get Bennies. In Sir Nick's case, Charley starts each session with 3 Bennies + 1 Bennie because of his Luck edge. Wild Card NPCs get 2 Bennies each and the GM starts with 1 extra Bennie per player per game session that he can use on any NPC, including Wild Card NPCs. Since it's going to be only Charley playing, that means I get 1 extra Bennie per game session. We'll cover what Bennies do later.
Finally, Extras, also known as Mooks, are much weaker than Wild Cards - they can only take one wound, they get no dedicated Bennies (except the extras that the GM chooses to use) and they don't use the Wild Die.
