Everyone: pro tip: you gotta prioritize shooting and killing the big black balls. It seems to reduce the add spawns.
Got mine too! So sweet! Looks like a KF boss wrecker.
Black Spindle get. Thanks to Optimus and Broodshadow running it with me. The Taken section was alot tougher than I expected. Basically need to clear through Thieves Den strike (minus the Devil Walker) in under 10min. That includes killing any adds alive after the boss dies. Secret things like this are making this game awesome.
