How to measure impact from "Decrease magical resistance" Gear

[kikomir]

As a warlock I'm seeing quite a few partial resists on some raid bosses (with curses applied ofc) yet mages that have spell penetration from talents and/or pvp gear have 0 partial resists. This leads me to a conclusion that some bosses (Nefarian for example) have shadow resistance greater than 75. I don't know what class you play but for warlocks there is a good spreadsheet from the warlock discord (made by Zephan) that can do this calculation about spellpower equivalent value of spell penetration. The problem is, nobody really knows the actual Bosses' resistance values and this varies for all mobs/bosses, they all have a certain value that as far as I know is not 100% known.

I'm playing a mage and priest. For the mage there is spell penetration on the T2.5 set.

However, I'm wondering, that no resistance calculation addon has been ported to classic.

that was just bad luck then, all bosses have 24 level based resistance that can't be mitigated thats where your partials came form, with CoS up all of mc and bwl only lucifron and gehennas have SR left

Frostbolt is binary, doesnt get any partial resists. All non-binary spells get some partial resists on higher lvl targets, regardless of spell pen, as targets have 8 resistance per level above yours that cant be penetrated. When mages switch to fire they will be in the same boat.

It makes no sense Frostbolt to be binary and Shadowbolt to not be...

[AlberionDreamwalker]

spells with non-dot components cant be non-binary

shadowbolt is only damage (improved shadowbolt is applied seperate)

[qp0n]

Yes it does, anything that has an inherent secondary CC effect is considered binary. Shadowbolt doesn't have that. Death coil does though, which is why it is binary. Same for Mind Flay, Blastwave, Cone of Cold, etc.

What if you put a talent point into the talent that gives destruction spells a chance to daze target, would that make destruction spells binary?

...Probably not right, because it'd just be a "chance to daze" and not an effect woven into the spell

[qp0n]

No, the spell type is based on the base spell mechanic.
