Welcome to Librarium Online!
What exactly is a BoneSinger? I've heard about them here and there but I have never actually worked out what they do. I have not seen any rules for them but I have seen models of them for sale on Ebay.
Are the like Farseers or do they have their own set of rules?
Bonesingers are eldar psykers that make stuff out of wraithbone. GW made a bonesinger model (limited edition I believe) but there have never been rules for one I have seen some used as farseers or part of a conversion. On a side note there is a craftworld whos bonesingers are so good they can work even on the battlefield. I would imagine that they would work similar to a techpriest or techmarine fixing damaged vehicles on the fly.
When/if eldar gets redone, I would not doubt that they will be included in it.
But he is right, they are like the engineers and construction workers of the eldar race. They build psychically. If you want to see a little bit of what they do, look up Dawn of War game footage of eldar. They are the builder units of the eldar in that game.
