Do I get it right that if I use a Sunder to break the immunity that they still got 95% res and if yes do I also get it right that if I use infi with conviction lvl 12 what reduces the res about 85% that I just need -enemy res 115? to get them to -100 so i get the max dmg out of my skills even if they would usually be immun?

Thx for reading and helping out :3

Conviction lower resistance and cold mastery work at 1/5. Facets work well

sunders sets resist to 95%
conviction, lower res and cold mastery only work at 1/5 effect vs broken immunes, meaning infy only gives -17 instead of -85
everything else works as usual, e.g. griffon/facets/flickering/... have no penalty

alright thank you :3
