I am co-DM'ing a campaign, and in our party we have a monk. Everybody has magical weapons that work with their class, but I feel the monk is a bit left out since he doesn't get any magic weapons since he is at the point where unarmed strikes do as much damage as a two-handed quarterstaff strike.
I asked the other DM if we could give him magical +1 or +2 fistwraps or knuckledusters, but he is hesitant since he worries about balance.
Our party is around level 13.
Are there any magic "weapons" that a monk could use and still be considered 'unarmed'?
