(Active): Gangplank fires into the air, disabling his passive boost but inspiring himself to gain an additional 12 / 19 / 26 / 33 / 40 attack damage and 8 / 11 / 14 / 17 / 20 % movement speed, with nearby allied champions receiving half that amount for 7 seconds. He regains the passive when the buff ends.
taking down turrets
helping teammates get a little extra speed when they need to escape
when you need more speed to catch up to an escaping champ
Raise you're ad and speed on the cheap side.
Many like to max it at lvl 18. I recommend to lvl this first over parrrley IF you're laning with someone that's squishy or lacks a decent ranged attack. Why? Because once active, early game you blow anyone in your way and parrrley will hit for more damage since it scales with your AD.
Else lvl parrrley and raise morale together.
