I was also a much better magus than I had been. The abilities I had gained came with specifically quantified skills, all conveniently ranked by Web of Magic's rating system. I had the Territory Creation skill, which allowed the creation of dedicated spaces where magecraft was strengthened, mana could be stored, and spells could be performed more efficiently. Unfortunately, at E rank the skill was barely able to accomplish anything, taking considerable effort to set up even the most basic of workshops.
In terms of casting skill in particular I had received the Magecraft skill at rank C. It wasn't enough to give me any earth-shaking magical abilities, but it did grant a comprehensive understanding of modern magecraft. Compared to my previous specializations it was incredibly broad while still being at a functional level. Essentially, base proficiency with all trades, master of none save the arts I had previously mastered.
