Description
Savage Worlds has everything you need to play narrative or miniature-based games, with quick, simple, yet comprehensive rules for everything from combat to Dramatic Tasks, Chases, and Interludes. The emphasis is on less bookkeeping for the Game Master so she can quickly and easily create worlds and adventures for any setting and focus on the players and their actions to keep the action and story rocketing along.
System Overview & Key Features
Step Dice Mechanic
Instead of fixed numeric modifiers, character attributes and skills are rated by die types, ranging from a four sided die (d4) to a twelve sided die (d12). To succeed at a task, a player rolls their skill die and tries to hit a standard target number, which is almost always a 4.
The Wild Die
Player characters and major non player characters get to roll an extra six sided die called the Wild Die whenever they make a trait test. They roll this alongside their standard skill die and take the higher of the two results, significantly increasing their baseline competence.
Acing (Exploding Dice)
If any die rolls its maximum possible value, such as rolling an 8 on an eight sided die, the die "aces". The player gets to roll that die again and add the new value to the total. This can chain multiple times, allowing for massive, cinematic successes against all odds.
Initiative with Playing Cards
Instead of rolling dice for turn order, combat initiative is tracked using a standard deck of playing cards with the Jokers left in. This makes tracking turn order incredibly fast and visually clear. Drawing a Joker grants that character a powerful bonus to all their rolls for that round.
