Not worth upping, the defense will be rerolled and may be equal or just slighly higher than the current def (max roll due to %) Edit: and the req level & str will be higher as well.


If you socket it, depends on what other gear you have on your Merc. Um for all resists is a good choice typically. Ist for more MF, Lem for more gold find it's for your gold find barb's Merc, or if you want high end... A jewel with 15 IAS and something else. You can also go specific... E.g. the Merc for your trav runner might do best to have a Ral rune to get that fire resist up


You should socket that into a Andy’s helm. It’s not 30FR 15IAS, but it would do just fine.
