Gathering Power

Gathering Power was a Generic Talent that granted increased Spell Power upon scoring a Takedown. The bonus damage was sizeable and gave a hefty advantage if you survived, but dying was very punishing. The Talent was removed from many Heroes to instead provide them with different, more unique Talents that suit their kit better and weren't simple "win more" talents.

The Talent is no longer available on any Hero.

Old versions
Originally the Talent immediately granted 8% Ability Power, increased by 2% for every Takedown up to additional 12%.
