Salve Soldales!
It's the second so I'll post two!
The first would be to make Fixing an Arcane connection something a magus can do as a seasonal activity in combination with other things, the way it can be done with Solomonic Magic. if performing multiple activities in one season, this activity is considered a Level 5 effect, and would cost a pawn on Vim vis.
The second would be to duplicate an existing Arcane connection:
This requires a pawn of Vim vis and an appropriate object to become the new connection. It does not affect the original connection, and so creates a new Arcane Connection. When performing multiple activities in one season, this is considered a Level 5 effect.
