Thank you this really helped the character development:
Here is how the Picturamancer ended up
After ages of trying to do this we found a nice simple solution, the character can use Performance to make declerations during the ritual phase to tag it for the ritual, flavour wise this can include mixing ingrediants into the paint etc....
Its a nice thematic work around driven of the characters High aspect, and easily usable as well by a Focused Practioner, The Character has the ability to work only effects that he can paint so Wards which can be painted onto any surface of the building or hung in a suitable venue, Summoning and binding (which works in a really cool way the Canvas is placed inside a ring of Copper Frame and then the summoned creature is bound to its 'image' as drawn by the character...), and Crafting (this includes special paints, not potions that allow certain effect, focus item paint brushes... you get the idea)
Any way I hope this helps with your idea it took a while to get the balance right with this character but now very very happy with it.....
The only other thought we did have and where we then started to struggle if you could use an Stunt to replace Lore with Performance, in a way of 'feeling' the spell through his art, making it more of an Art than a science, however had no way of really setting conditions of the trappings of the Lore Skill and struggled with it for ages, and in the end the decleration just felt better... However if you can see a way that this would work it would make a real difference to the character as he is just creating magic with no Lore, meaning he will be unaware of what the consequences would be.... a great hook early on...
