I have several pieces of blackrock, small and large. What do I do to redeem them, and is it worth it to do so at this time.

Thanks ya'll

Im not entirely sure where you have to redeem them, but its black monk type npcs your after... In regards to trading them all in thats entirely upto you but I would imagine it makes no difference what so ever

The traders (dressed in black)will be in Haven on regular production shards (Occlo on Siege), but not spawning at the same place all the time. The question becomes what happens when enough people turn in blackrock??

hmmm....

Just to add:

They spawn in the wilderness, not in town.

Their name appears in yellow as "a trader"

To trade in the BR, just drag and drop the piece on them.

They seem to be in a spot for about 2-3 minutes if my estimates are right.

It almost seems taht how much BR they get may effect how long they are in a given place.

I traded in 2 pieces from ToT2 and 6 pieces from mining at the Motherlode and got 20 Corruption, 10 Taint, 10 Putrefaction, 10 Muculent, 10 Fire Rubies, a 10 charge ToT2 dye, and a pair of Gloves of the Sun.

Considering that I have no real need for anything but the dyes (they came in a great shade of Shadow too, my favorite! ) it is still pretty cool that they came up with a neat idea to get this stuff out of my house!

On Catskills, the traders spawn in the town as well as the wilderness.

They only stay for a few seconds on each visit; about 10 seconds is as long as they remain.

Once you see a trader in a particular spot, you can remain in the area and the trader will eventually spawn in the same general area on approximately a 10-15 minute cycle.

You have to be quick. Drag and drop your blackrock on the trader as quickly as possible before (s)he recalls out.

You should consider before trading in blackrock. From my own observations, the trade-ins reported on the production shards aren't as good as the ones reported on Origin; the devs may have tweaked the loot downwards, although none has admitted to it. It's possible that the traders have an evil purpose, so if your characters are the lawful/good type, it might be advisable to hold your blackrock for the Moonglow mages or a later, officially sanctioned, turn-in.

you all see this link yet??
