====Hero Dice as Effect Dice====
With this mod, hero dice may also be spent to substitute for low effect dice from dice rolls. Used this way, the player spends a plot point and uses the hero die as the effect die instead of one of the dice from the roll. If this application of hero dice is used in a game, the heroic success does not also step up this new effect die. That only applies to effect dice sourced from the die roll itself.

''For example, after winning a contest with a GMC, your player character might only have a d4 left in the dice pool to use as the effect die. If you had a hero die banked, such as a d8, you could spend a plot point to switch out the d4 with the d8.''

Multiple effect dice may be created in this fashion for a single outcome by spending more PP.
