I think its a highly under-rated ring. Its very Cheap, comes with MP+ and Enmity-. Its a cheap alternative to the Serene Ring. (Now dont get me wrong. Serene Ring >owns> Peace Ring, But peace ring is cheap ;P)
Though You could get Vilmas Ring, Vivian Ring(yaright), Carect Ring, Astrals, Ether Ring(which has gone down alot now) or Serket Ring(woot). But again. Cheap alternative.
