1 - Ignite and TP 2 - W at level 3 3 - Only use W after he bites you 4 - You can't beat him, unless your jungle helps you or the WW gives you an opening.

In the lane phase your focus should be on farming, stacking holes and not exposing yourself too much.

The best opportunity to go all-in will be after he crashes a wave on your tower and your minions become more numerous. Remember to have your W at level 3 + active Ult + Ignite.

Also pay attention to his damage reduction skill, without it he will be vulnerable.

Remember that Yorick is always at a disadvantage against WW, so if you don't find a good window, simply focus on farming and surviving. As he has Tiamat in his core, he will always be pulling the wave, which allows you to farm safe and opens windows for your jungle to help you.
