Multiple Beastly Attacks cast on a resonator give multiple instances of the secondary text. For example, if "Hunter in Black Forest" has two Beastly Attacks cast on it, and it attacks into an opponent's resonator, it will deal 3000 damage ([300 + 600 + 600] x 2) to the opponent. If the resonator already has the ability gained with Beastly Attack, it triggers once for each instance of that ability the resonator has.
