if you're on nl east, i have a 2nd eth 3 skt reaver and upped eth rib for trade if you're interested. they both have lower ed though.
reaver getting 1k damage? i dont know about that, i guess it may with 7/4fpa fury (2 x ed/ias zod).
personally, i would go for the 7/4fpa reaver if it was for pvm.
edit: i found my eth rib at shenk. (both of them iirc)
as for the reavers, i traded for them.
