So, I have a holy magus of the method of purity. One of the big restrictions of holy magic is that you can't use hermetic voicing and gestures so if you didn't build your virtues for it (which I didn't) you're at -15 for spellcasting. The two ways around this are to make a 15+ theology roll, which is hard, or use the action associated with your method. In purity's case, that's doing something strenuous enough to cause a level of long term fatigue or a light wound.
And so, I cast a modified Endurance of the Berserkers (not affected by wound penalties), and modified Bind Wound (no risk of worsening wounds), then stab myself every time I cast a spell. At the end of the day, cast a spell using the guideline from Soceitas pg 100 to reduce all my wounds by 1 stage which, because of the benefits of Holy Magic, costs only long term fatigue which I get to sleep off anyway.
All of that sound kosher? There any hidden interactions that I missing? It's a few steps, but I like knowing all those spells anyway so it seems like a fine cost to pay to juke that downside.
And speaking of Holy Magic's ability to dodge vis costs, the Creo Mentem and Creo Corpus guidelines to permanently raise stats seem...really strong. The +5 versions get a bit hard to learn, to be sure, a level 60 spell is gonna be out of my reach until raising my int with it isn't a huge gain, but the +3 ones are very doable and even the +0 ones to buy back stat points sold off at character creation all for free seems strong to my novice eyes. Since long term fatigue only takes a nights rest to work off, it's entirely feasible that I could just cast it right before bed and not even lose seasons to raise the entire covenant's stats to whatever level I can learn. Yes I have to learn a new spell for each stat, but that's...4-6 years of labwork to get what would be a lot of equivalent virtue points? Seems like a good rate.
Has anyone played with this and felt it was too strong, or if the costs of holy magic + time + warping balance it out? If it felt too strong, what are some sensible limitations to put on it?
