Dragon Frenzy

Description
Nibbs strikes at enemies with her claws, dealing damage. She will gain a stack of a frenzy for each enemy unit hit (but not structures) which increases her attack speed. Up to a maximum of 4 frenzy stacks can be held at any time. If Nibbs doesn't hit enemy units with her claws after a few seconds, her frenzy stacks will be reset to 0.
