I counted, and counted, and counted, how many brown chests I opened (and didn't open) inside The Boyhada Tree before I got my Carver's Torque.
Total brown chests : 487.
Total brown chests opened: 451, got it on 451st.
Days spent in The B.Tree killing mobs & popping chests: ~5hrs a day for 7+ days, that was WITH GoV Treasure Chest lv.5 enhancement since I logged out there and didn't zone out.
This was not my version of fun. :/ but it did let me get the +13 for my WW.
