Gangplank can purchase upgrades to his ship in the store at the cost of 500 Silver Serpents each, which improve Cannon Barrage:
- Death's Daughter: An initial mega-cannonball lands in the center of the area of effect, dealing a cluster's worth of true damage and slowing enemies within by 60% for 1.5 seconds.
- Raise Morale: Allies within the area gain 30% bonus movement speed, persisting for 2 seconds after leaving it. Gangplank can also benefit from this effect.
- Fire At Will: Fires 6 additional waves with increasing rate of fire over the duration.
