When in wolf form, the Druid using this ability enters a frenzied rage, viciously tearing into foes and becoming heartier with each consecutive attack.

Detail

Stat	Value
+% Attack Rating	10 + (10*slvl)
+% Damage	45 + (5*slvl)
Charge level	lvl = [slvl/2] + 3
Maximum +% Movement speed	min(10 + [60 * [ (110*lvl) / (lvl+6) ] / 100] , 70)
Maximum % Life Stolen per hit	4*lvl
Duration (Seconds)	20

After the first successful attack 4% Life Stolen per hit and movement speed for charge level 1 is added for duration, and every successful attack following will reset duration and increase charge level (resulting in +% Life Stolen per hit and movement speed for that level being applied to next successful attack) until the maximum charge level is reached.

Tool tips incorrectly display maximum 8 + (4*slvl)% Life Stolen per hit.
Switching to another attack will result in % Life Stolen per hit being applied to that attack and and + movement speed being applied to movement speed until duration expires.
Weapon speed and weapon Increased Attack Speed are normally most significant factors in determining attack rate.
Successful attacks use Feral Rage attack rate, unsuccessful ones use that of Attack. [1] [2] [3]
