Arthros produces a par of shinning rings from his satchel. I hope this works here.
"As we expect battle soon, I might suggest one of our fine warriors put one of these on. While I wear the other, it will serve as a connection, transferring a portion of their wounds to me through the linkage. While not terribly pleasant for me, it has served well in previous adventures." He looks to the large warrior and the cat woman, holding up a ring.
platinum rings = focus for shield other, 1/2 damage goes to Arthros. Should be warn by our main tank.
