I went out and did about 150 level one maps back too back. In one chest, and only one chest (about #7 as I remeber), did I get a Surge Shield. It has; 50 charges, Brittle, Surge Mana Regeneration, cold resist 1%, Str Req 35, Dur 75. It has absolutely no other bonus on it what-so-ever and has 0 points on the imbuers scale value. I normally see some other bonus on them. Is it rare in any way? Im thinking only the fact that it's at 0 points maybe? Anyone?
