Fray Inlay
Use it on your automaton to press it into a plank of its Sigil ring — thorns: whoever strikes it takes 1 damage back, Angle throws junk back once more. One inlay per hull, two in speculum, fluxsteel, wax and burl, one more with a Thinking head; at most two of one current. Shears take it off whole.
