I was wondering if someone has tried to implement the Ars Magica magic system into Rolemaster, and how.
I guess you could assign some cost to the forms and techniques, maybe scaling its values to a 100-based system (multiplying by 5 would be pretty accurate). I'm not sure if the magic realms would be obsolete or just affect some form and/or technique cost. For example, essence could be related with aquam, auram, ignem and terram, and mentalism obviously with mentem.
But what about formulaic spells? Use only a more powerful version of spontaneous magic?
I haven't thought deeply about it, I would love to read about it if someone has, if someone tried and failed or succeeded, and the exact mechanics involved.
