Here is a traditional sorcery grimoire template for Mythras – this is a first tryout for my campaign’s first sorcerer. This is traditional in a sense that the only options it uses is the duration length option. I will be making similar ones for various sorcery schools which have different components.
How one could use it. Player should fill it with the sorcery information relevant to your players’ sorcery grimoire. During game it should help how the various shapings the player wants to use affect the spell.
Here is Grimoire of Ravenous Shark as an example:
When he selects as a spell Shapechange to Shark with his 4 shaping points he could put 2 points into duration getting 15 minutes of shape change. After this he could put one point into targets getting 2 targets (perhaps himself and a companion). After this he could put remaining 1 point he can put 1 point into magnitude getting a magnitude of 2 and have some protection for resisting dispelling the shapechange.
This would take 1 MP for the spell itself and 1 for each shaping (Duration, Targets and Magnitude) = 4 Magic Points for the overall spell cost. It would take 4 turns to cast the spell (1 for the spell itself and 1 for each shaping).
