Last night I bought an overclocked item for my armourer. It gives an extra 3% success chance when equipped in charm slot. Question is, if I got another one, would it stack giving me 6%? I suppose for 6g I should have just bought it & tried it.
The thing I bought is for level 54. Are there higher level ones than this?
I think it was called something like 'Qeynos guide to Wallburring' or similar bizarre name.
