Myself and a couple friends are creating a new RPG system. The system works on one primary mechanic and almost everything is a variation of that mechanic. You build a pool of 12 sided dice and roll equal to or under a target number, count successes and compare with the difficulty. The purpose of the system is to be able to recreate any book world and play in the favorite worlds of our literary heroes. Other systems, especially D20 magic, CAN NOT duplicate any magic system like allomancy.
Long version: There are 9 attributes, 3 each for physical, mental and social. Each attribute gives points of effort which we use cards to represent. You get to use three attributes in a turn but can use as many points of effort from those 3 attributes as you have available. Almost everything takes effort. So typical round... you pick your 3 physical attributes and have 2 effort for each, 6 effort total. You move (1 effort), open the door (free), move again (2 effort for second move), attack (1 effort) then decide to save the last 2 effort for defense. The attack consists of 1 die for the 1 effort spent plus bonus dice for your skill level (let's say 3) so 4 total dice or "dice pool", written 4DP. The target number is based on the higher from your skill level or base attribute. Starting attributes are target number 3, written T#3. So the attack is 4DP/T#3. You roll the 4d12 and count how many are a 3 or less... probably 1 in this case. The difficulty to hit the defenseless creature was 1 so you do damage.
Now, Allomancy:
Potential spoiler alert if you havent finished Mistborn book 3: The Hero of Ages
I'd like feedback, even if it's negative. It makes the system better in the longrun.
Thanks
