Okay, I'm working on an excel spreadsheet for monster damages and I want to be able to have it figure out the average damage for various levels of resistance... and I have no idea how to do that.
I do know that, for instance, 2d6 (avg 7) - 7 is _not_ average 0 though
3d6-4 is 10.5 + 1/216, reflecting replacing the 1 damage _not_ lost in the 1 in 216 chance of 3 1s.
2d8-4 would be 9 - 4 + 2/64 (1/64 off by 2) and 2/64 (2/64 off by 1) I think.
So how do I express that in a spreadsheet... ideally I'd like to be able to enter the resistance in a separate cell, but I am okay having duplicate pages for resist 5, 10, 15 and doing the work myself if it's too manual to be completely variable but is still very fast.
I guess worst case scenario, a link to a site that gives me the average of an arbitrary dice and bonus/penalty that treats negatives as 0 would cover my needs.
