As for the focus, I was going to build it myself. How would you treat that? I'd have to first make a Formula for it, then Enchant the Focus. How would that work during downtime, if at all?
I'll buy the Binding skill (4 karma), and improve Summoning to 3 (6 karma), and that'll be all for now.
I'd also like to purchase R4 Binding Materials (2000 NY), and maybe bind a spirit, or two. But that would need a lot of luck on my part with rolls, and I never seem to have that when it matters.
