I just start at 1 and go up from there. So say someone has a 20% failure chance. Before rolling anything else, they would roll the failure chance, and it would fail on a 1-20% roll, otherwise cast as normal. Hope that helps.
Hi
anther newbie question from me,I've been reading about Arcane spell failure chance,the failure percentage varying according to armor worn-etc.When you roll your Arcane spell failure check,what is the target number? how do you work out the percentage check?Could you give me a "in game" example
I don't get it.Sorry to be such a newb.
Thanks in advance
Off the cuff, I'd say that every time you try to cast a spell (that has a somatic component) while wearing armor/carrying a shield, you roll percentile dice. If you roll your spell failure chance or lower, you lose the spell, but nothing happens. Also, since all spell failure chances are expressed in increments of 5, you can always divide by 5 and roll a d20, if that's easier for you.)
Example. My wizard is wearing a chain shirt and has a normal buckler strapped to his arm. Chain Shirt has a 20% spell fail and a buckler has a 5% spell failure. Added together that's 25%. Every time he casts a spell that has a somatic component, he rolls 1d100. If he rolls 25 or less, he loses the spell, with no actual magic happening. Personally, I would divide by 5% and roll a d20 instead. Then, I lose the spell on a 5 or less.
