How does resistance work exactly? I currently have 80/75/75/75 in hell, but whenever i face Infector of Souls in the Chaos Sanctuary i lose hp a little too quickly. This is my understanding of resistance. At 80FR, monsters who do fire damage only do 20% of their damage. So in this case with Venom lords they will do 20% of 94-150 which is 19-30. Is this correct? Also is it worthwhile to vex my shako so my FR is boosted to 85?
