Level 3
Enlarging Wrath.
While Raging, you grow 1 size category, take half as much forced movement and apply Dazed on crit.
Giant’s Hurl.
Action: Expend a Fury Die to fling an adjacent smaller object or creature a number of spaces up to the expended Die’s result. Alternatively, propulse an adjacent willing ally for the same amount; if they land at range of an enemy they may immediately roll an attack against it for free.
Level 7
Hulking Stride.
Whenever you move, you may power through minor obstacles on your way and shove any creature up to your size aside; those smaller than you also fall prone. You gain Resistance to any damage you would take while moving.
Level 11
Terrifying Roar.
Free Reaction (when you become Bloodied for the first time each encounter): Rage automatically; all enemies within Reach 12 take LVL Psychic Damage, and those smaller than you are Frightened until the end of their next turn.
Level 15
Maximal Fury.
(1/Safe Rest) Action: While raging, grow 1 additional size category, become immune to forced movement and ignore Difficult Terrain. In addition, forced movement damage you cause deals d12s instead of d6s. It recharges whenever you enter the Dying condition.
