Also keep in mind that poisoning with magery has different formulas here than on other shards. Its a bit more potent but still relies on magery + poisoning skill levels.
I found the formula on many websites: Succes of Poison spell is (Magery + Poisoning) ÷2
With 100 magery and 50 poisoning it's 75% against 100% resisting spell. There will be no success on a dexxer with around 70% magery and 30% poisoning. I stay corrected too. GM poisoning make sence with GM magery, but below is a lower chance for a successful cast.
