Hero Points
Every character starts play with Hero Points. Hero Points provide a player with the means to alter d20 rolls in dramatic situations. After a die roll, but before the DM reveals the results, you can decide to spend a Hero Point. For a character, spending a Hero Point adds 1d6 to the d20 roll, helping you get closer to or exceed the target number.
A Hero Point can be applied to a single die roll when making an:
attack roll
skill check
ability check
level check
saving throw
You can only spend 1 Hero Point in a round.
When you spend 1 Hero Point to improve a d20 roll, you add 1d6 to your d20 roll to help you meet or exceed the target number. You can declare the use of 1 Hero Point to alter a d20 roll after the roll is made, but only before the DM reveals the result of that roll. You can't use a Hero Point on a skill check or ability check when you are taking 10 or taking 20.
