Hello, I'm making some improvements to my Anima campaing and I need some help to figure out how to implement the open rolls and fumble in this system. For the open roll, when you roll a 11, 22, 33, 44, 55, 66, 77, 88, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99 and 100 is an open roll, if in the second roll is a 91 or more its another open roll, then in the third is a 92 or more its another open roll and so on untill you reach the 100, 100 is always an open roll. The fumble works this way: When you roll an 1, 2 o 3 its a fumble. Then you calculate the fumble total, if you rolled a 1 you have to roll 1d100 +15 to calculate the total fumble, if its 2 you roll 1d100 and if its a 3 you roll 1d100 -15. Sorry if its hard to undestand, my english is not so good.
