It feels like i’m the only one that has bothered looking this up, if you look at the Slow spell that they cast on you (on wowhead) you can see that its called “nature_slow” and you can also see that the school is nature.
Having two NR rings in there have increased my success rate from 92% to 98%.
Also, does no one else bother with Magic Resistance Potions? They go for like 20s each and gives 50 magic res.
