Beast Mastery leveling order 31/20/0
Beast Mastery: Deadly Aspects 5, Endurance Training 1, Focused Fire 2, Pathfinding 2, Bestial Swiftness 1, Unleashed Fury 5, Ferocity 5, Summon Hawk 1, Intimidation 1, Bestial Discipline 2, Frenzy 5, Bestial Wrath 1
Marksmanship: Lethal Attacks 5, Efficiency 5, Careful Aim 5, Trueshot Aura 1, Mortal Shots 4
This 1–60 path matches the level-30 shape of Deadly Aspects first, Summon Hawk at 25, Intimidation at 30, and the "beside a healer" order to 30. Solo, take Improved Revive Pet instead of Focused Fire; alternatively, start with Endurance Training 5 instead of Deadly Aspects. With the Talented legacy perk every step comes up to five levels sooner.
Beast Mastery, level 30 21/0/0 Tested in beta
Beast Mastery: Deadly Aspects 5, Endurance Training 1, Pathfinding 2, Improved Revive Pet 2, Bestial Swiftness 1, Unleashed Fury 5, Ferocity 3, Summon Hawk 1, Intimidation 1
Level-30 build: Deadly Aspects, Pathfinding and Improved Revive Pet first, Summon Hawk at 25, Intimidation at 30. Focused Fire is the strongest DPS talent available for the flexible points; beside a healer, swap Improved Revive Pet 2 for Focused Fire 2 (the levelling order's shape). For up to 5 extra Legacy points: finish Ferocity 5, then Bestial Discipline 2 and Frenzy 1. Alternatively, take Deadly Aspects 5, Endurance Training 1, Focused Fire 2, Pathfinding 2, Bestial Swiftness 1, Unleashed Fury 5, Ferocity 3, Summon Hawk 1, Bestial Discipline 1 (no Intimidation, no Improved Revive Pet). The build maxes Unleashed Fury, which raises pet damage. Order: the Beast Mastery levelling order above, keeping this build's talents; Improved Revive Pet, which that order skips, go in where the tree allows.
Beast Mastery, level 60 (projected) 31/20/0 Guide's pick, untested
Beast Mastery: Deadly Aspects 5, Endurance Training 1, Focused Fire 2, Improved Revive Pet 2, Bestial Swiftness 1, Unleashed Fury 5, Ferocity 5, Summon Hawk 1, Intimidation 1, Bestial Discipline 2, Frenzy 5, Bestial Wrath 1
Marksmanship: Lethal Attacks 5, Improved Stings 3, Careful Aim 5, Rapid Killing 2, Trueshot Aura 1, Mortal Shots 4
The standard 31/20/0 (alternatively, take Efficiency 3 instead of Improved Stings 3, and a fifth Mortal Shots instead of Trueshot Aura). Beta theorycraft: nobody can test level 40+. Order: the Beast Mastery levelling order above, keeping this build's talents; Improved Revive Pet, Improved Stings and Rapid Killing, which that order skips, go in where the tree allows.
