Difficulty of rolls in Mage 20th (and maybe Revised?)
I'm looking through Mage right now because I'm trying to figure out the dice math, and I want to benefit from the experience of those lucky enough to have played:
First, is casting high level (highest sphere 5 or so) vulgar with witnesses nearly impossible? 'Cause if the difficulty is 9 or 10, even max Arete will barely help you do more than augment your senses, which isn't really vulgar anyway.
If so, how do you do that? Just stack quintessence or work near a node? Just wondering if I'm getting this right and witnesses are thematically supposed to make magick SUPER hard.
Second, what level of Mage does the typical game assume? 5th edition, being street level, assumes and balances around neophyte characters (except maybe Hunter?). What about Mage 20th? Because if a starting mage at creation has 1-3 Arete, then they're rolling 3 dice and probably aren't doing anything more impressive than 2-success feats, which are...fairly tame once you incorporate range, targets, damage, and duration.
