Hey guys, so I would like to contribute this info that I tested tonight pretty interesting, not sure if it will get nerfed.
Basically the new 1.04 legendary Sever has a affix "enemy's are slain"
which means you do a CRAZY crit hit for every last killing attack given.
not too crazy stuff, but coupled with 3% LIFESTEAL (not loh) it can heal you up to over 10khp!! (depends on your dps too)
Works best for barb or a build that uses offhand weapon.
(ps, I would like to be upgraded to view elite section if possible)
