level 60s with 450 engi - remember those days? Back then - I'm positive, you could get 375 "insert prof." at level 39. Look at "mymainfailed"s 375 enchanting, as an example(GFed now though)
About DeathRay, what's the damage you do with DeathRay?
We never could get 375 eng?
The only profession i was aware of that could get over 300 was Mining and enchanting.
As far as Gnomish Death Ray, a ret paladin could 1shot w/ this:
HoJ + DeathRay + x3 TV.
