Question about Acid Reaper weapon components

Hi everyone,

Im playing an Acid reaper with 5 WPS , bone harvest , lethal assault , shadow strike.

Currently the components I have been using are vitriolic stone for the envenomed weapons buff and Shard of beronath cause thats the only default attack replacer i can find.

However, I was wondering is it worth to use blessed steel over one of the previously mentioned components for the sacred strike which hits with both weapons for 350% and basically does more dmg than shadow strike. And should I be using the chaos strike component as well for the same reason?

where is cthon when u need him
