I wouldn't recommend using a shako on a merc because the only mod decent mods is Life and DR.. I'm using an Eth Gaze which seems to be great 20% dr with life leech which seems to be more important than just added life.. If you were on West Ladder with an Eth Shako it only costs 1.5 Ist for a freaking zod.. So cheap... I'd love to have an Eth shako on my Pally to match the eth valor
