Scrawling the rune for connection onto the hilt of one of my knives and then adding some blood serves as my quick proof of concept... and seems to work well. My magic is just connected to the knife now. Moving it around with telekinesis requires very little focus, it’s almost like moving an additional limb. Furthermore, with my sensitivity to magic I’m always aware of it, even if I close my eyes. A sort of magical proprioception. With this in place I could easily split my attention between multiple knives and still duel, which would increase my combat power significantly. Unless I run into some sort of hard counter, this is likely to become the backbone of my fighting style, as there's no reason I can't extend it to other things as well. Knives work well for offense, but I can easily grab sets of plates and use them to catch curses that I can't block conventionally, like the Killing Curse.
