And I think there was a Nep post on officials to this effect, that Gates is a sliding scale that starts with the first bit of -AC that you put on.
Based on my experiences, it's pretty negligible at sub -100 AC*.
By the time you get to -400 AC it is absolutely nuts how good it is. Stacked with Rager Resist and Svirf Stoneskin I was taking
decimates from The Archmage of the High Tower of Sorcery while my groupmates (also with Rager Resist) were taking
***DEMOLISHES***
*I understand that "sub -100 AC" is actually superior to -100 AC, but can we just ignore the "-" in front of our AC numbers when making
comparative statements?
