The Ferocity Mastery Tree is one of the three Mastery branches. It replaces the Offense Mastery profileicon Offense tree of previous seasons.

As of Season 2016, masteries were upgraded to a new system. Whereas previously you could invest in as many masteries per tree as you had points left to spend, each tier now has a maximum number of points you can allocate. As such, you may only spend up to 18 points in any one tree.
