Lumberjack is a gathering profession focused on gathering wood. Seven different levels of the lumberjack gathering profession can be unlocked on the Destiny Board. Each tier level allows you to wear a new and improved tool as well as gathering gear starting at Tier 4. Lumberjacks use the woodaxe to cut down trees and gather wood.
Starting at Tier 4, each destiny board node unlocked will increase the item power for all lumberjack gathering gear by 0.2, the item power of the same tier gear as the node by 1.5, the gathering yield of the same tier resource by 0.5% and the harvesting speed of the same tier resource by 0.5%.
(A table that shows how much fame is needed to unlock the different nodes on the destiny board should be here.)
