Focus on farming and poking your enemy, try to stack the passive as much as possible. In the early game, you can eliminate your lane opponent if they make a mistake, but don't try to force trades and end up dying, as it will set back your game significantly. The ideal strategy is to poke and eliminate the enemy with the help of your jungler.

Considering that only Gangplank's R deals AP damage, don't waste it carelessly. Try to use it to hit at least 2 people to ensure value for your ultimate.

Use your ultimate and deal damage in conjunction with the barrels. Remember, your only sources of damage are your ultimate and the barrels with Lich Bane.
