[QUOTE="Plane Sailing, post: 3412092, member: 114"] Another option might be to find a way of resolving all the dispels as one check. Use excel to work out a probability table - down the side you have the chance of succeeding the caster level check and across the top you have the chance of making it a successive number of times. The data in the middle of the chart shows the percentage chance of actually making that check that number of times - roll %age dice and read along the chart to see how many of the things you got rid of. This latter idea doesn't mean any change in mechanics, just uses mathematics to simulate the effect of multiple rolls in a single %age roll. I've created a simple table for this in excel and attached a picture of it here along with the file itself. As an example - Boffo (12th level) throws a targetted dispel at Zappo (15th level). The base chance of success is 35% (1d20+12 vs 26 needs a 14 or more, ie 35%). Rather than rolling lots of d20s, Boffo rolls %age dice and looks along the table. His chance of getting more than one success isn't that great. He rolls 20% and only knocks one spell off zappo. Zappo decides to return the favour. His base chance of success is 65% and if he rolls a 20% on his percentage dice he has knocked off 3 of Boffos spells. To be strictly fair, you probably ought to randomly determine which of the eligible spells are knocked off if the caster gets less than the total number on the target. [/QUOTE]
