Combos and how to play

Written guide · based on the official ability texts

Yuumi is a support who attaches to her allies: You and Me! dashes her to an ally, and in that state only turrets can target her. Prowling Projectile slows (more if the projectile flies at least 1.35 seconds), Zoomies only benefits the ally when she is attached, and Final Chapter heals and damages.

Harassment
Prowling Projectile Q You and Me! W Zoomies E

When: An enemy is within projectile range.

Prowling Projectile slows and damages (stronger if the projectile flew 1.35 s); while attached, you can steer it with your cursor; Zoomies gives your ally a shield and speeds.

Protection
You and Me! W Zoomies E Final Chapter R

When: Your carry is threatened.

You and Me! puts you safely on your ally, Zoomies protects them, and Final Chapter heals your allies while channeling.

The team fight
Final Chapter R You and Me! W Zoomies E

When: A fight begins.

Final Chapter channels five waves that damage enemies and heal allies; during it, you can move, attach and cast Zoomies.

Laning phase

Attach to your carry to protect them. Your passive heals you and heals your next ally when you hit a champion.
