Couldn't find a subthread on artefacts hence resorted to posting here.

I am currently lvl 28 Necromancer with equipment value 976. Would like to find out what is the appropriate equipment value I should be having as I have not replaced them for a long time (probably since lvl 25 or before).

The equipment: (value in brackets)
Stern Hand of War (168)
Gentle Hand of Peace (171)
Silk Hood of Mastery (182)
Sable Leggins of Domination (169)
Stole of Elrath Purity (166)
Iron Ring of Devastation (121)

Also, at which location can I buy suitable equipment for lvl 28 (that is better than my current one).
