These results tend to point towards resistances changing damage dealt and not chance to totally resist a spell.
The sample size was small, there were however 30 more Shadow Bolts fired at the Lasiien in a diff test, but we were both grped at that point so Las's Shadow Weaving would have scewed the results gained..
Hey Sax, was interesting getting slapped about by your bolts for an hour
On the first point there I don't think we really tested the resistance to a spell, there were for sure times i resisted but I can't remember when. I think you'd also need to test on higher and lower level targets to see how that influenced things as well. Point being, dont think you can discount that it adds or decreases your chances to resist the spell itself.
On the shadow weaving stuff I think you got confused (wondered why you disbanded during the test !

or perhaps i confused you! Anyway the shadow weaving, which is a priest talent, only affected us when PvE against mobs - not the results of your testing.
Overall I agree found it interesting. This is not DAOC whereby 60% resist is 60% mitigation. These figures seem to suggest that
-60 resist (from base of 10) = 62 dmg more ~ 1 extra dmg per 1% negative resist
+45 resist (from base of 10)= 74 dmg less ~ 1.6 extra dmg mitigation per 1% resist
This is only for your spell though, we'd have to test some other spells to be able to understand a trend.
Just based on that, I'm not convinced resists are worthwhile, given i could forsake +15 stamina say for +15 resist.
First i have to get the right resist type (shadow, cold, heat etc) only then would 15 resist would protect me on the figures above for 24 dmg each bolt.
An item with +15 stam (not uncommon at our level, but quite decent) translates to 150 hps for me as a priest. So I'd need to be hit more than 6 times for the resists to outwieigh the stamina increase. And again thats assuming i have the right resist type.
hrmmm
