Druid's Berserk talent has a chance to make the next Mangle ability cost no rage. The Mangle button could glow when this happens. An overlay may also be displayed, on Top, with the berserk texture.
The active buff, however, is not very interesting to track because it is fully predictable.
The difficulty is to know when the free Mangle happens. The talent has a buff component, but this is for the active buff, not the passive proc. Maybe Mangle morphs into a rage-free ability. This happens for instance for Pries, where the standard Flash Heal morphs into a mana-free Flash Heal with a different spell ID.
