has nothing to do with a nerf mindlessly. also we are not talking about overpowered or underpowered templates, we are talking about properties. and yes i know, we doesnt include mods, but i already told mas what i think about his solution to tune down necromages and told him that i think its stupid as it wont solve it, just change the template, its the casting cap that needs to be lowered on both skills when combined (as well as combinations of other skills, magery and necro arent the only skills).
right now, having a staff of magi in your hand is equal to having a black staff with +120 macing in your hand (assuming you have 120 magery). it gives you same ability to evade and to hit. there are a few differences in combination with other skills that dont matter thoo. further it is a mod only avaible for one group of template, namely mages. i would without a doubt call it the most powerful property avaible, id be interested to hear which one you think is more powerful.
