I managed to streamline 8 rules out of the basic modules on first pass – for an average of 18 rules per module. Not bad.
In the process, I decided to eliminate the Spell Maintenance perk. If a character REALLY needs to maintain at least three spells each round, he can take the new Bonus Action perk for Concentration (the skill that helps to maintain spells).
I mean, if all of your comrades are wearing magical armor that you created, someone failed to inspect the troops as they left garrison.
