Now I sin't a master of this yet but it ain't every collectible, which threw me at first.

Only the shite I dug outta an ephemeral node so fars been reducible. It's all had a level requirement, but when hittin' the skill it'd show up in the list and tell ya what the requirement is.

An for the record, I've reduced things with 0 collectible value. Maybe lower level stuff needs ta be a higher grade though, since before that level 56 node I couldn't break up anythin', even stuff good enough ta turn in.
