Hey all thanks. I appreciate the ideas and suggestions and comments. Honestly, though I have been a fan of Ars Magica for well over a decade now, and own and have read all the books, as nobody I know would ever want to play it I have not really focused on the fine print of the rules. hehe
But yeah, reading this thraed I can totally see how torch and bonfire are different (thus different spells) but that maybe lighter bonfire and stronger bonfire might be the same spell if its a small change.
I can also see the advantage of Adaptive Casting and also maybe Flexible Magic, though since my magus character has Flawless Magic its not really something he can easily get.
Which, actually, has me think of the question of there being Order Initiations for such abilities. The thing is I am annoyed that I can't use Order of Hermes as the 'Cult Lore' for such things and thus might have to make an actual mystery cult that the covenant he was at might have formed to better teach certain traits.
Also, as an aside, the whole ritual spells that raise Characteristics seem to me as something that a master might find it useful to use on their apprentices. Which is why, as a note, I established it that the covenant itself pays to have all apprentices and member magi under go the rituals to bring all negative Characteristics to at least 0, at covenant cost. Any wish to raise it above that, to the max of five, requires the apprentice/magus pay the vis cost themselves.
Right, anyway, not to derail the threat, but thanks for the comment. Very interesting stuff to hear.
I do think, by the way, that a ritual that conjures 10 structures could have the number of structures conjured vary from 1 to 10. My thought is though taht this wouldn't reduce the level or vis cost or anything. Sooo for a magus who was using it to conjure a number that would be best organized as a new spell might as well make a new spell. But yeah if they wanted to only conjure 8 sanctums they could with but the same spell. Additionally, I have no issue with saying 'you can change some flavor stuff, so last casting the building roofs were blue but this time its green'.
The big result is that there is no way my magus isn't taking the Adaptive Casting Mastery Ability for Aegis. that way whether its the aegis 10 or 30 or when he is an elder magus 120 it basically is one slot on his character sheet and one set of mastery abilities.
All that said, thanks for the comment, I appreciate it. I have been a bit distracted trying to figure out an adventure story for the Levant while also putting in time for my magus to train his apprentice (thankfully teaching can be done out of the lab so he can teach while on adventure) so I got distracted from responding here.
