I understand you absolutely. I missed an article or chapter about "How to play a magus?". Not the roleplaying part of course but the game mechanics and their contact with each other. Magic is quite difficult in ArM and as a beginner I had no idea what to learn, what do to, what worths to do and what are not.
See this about talismans, very interesting:
