Bop 'n' Block
STATIC COOLDOWN: 20 − 8 (based on level)
Bop 'n' Block

Innate: Periodically, Yuumi's next basic attack against an enemy Champion icon champion becomes an Excessive Force 2 unstoppable basic attack, gains Range icon 50 bonus range and becomes a Projectile non-projectile. This attack restores Mana icon 50 − 160 (based on level) mana and grants her a 60 − 400 (based on level) (+ 30% AP) Hybrid resistances icon shield that lasts until it is broken.

While You and Me! attached, the shield transfers to her Anchor.

Info
Notes
  • This ability will apply to a basic attack already in flight, but will not augment it into a non-projectile.
  • Bop 'n' Block will not proc if the attack is Counter Strike dodged or Yuumi misses the attack while Blind icon blinded. It will proc even if the attack is Spirit's Refuge blocked.

You and Me!

Active: After a 0.25-second Channeling icon channel, Yuumi Dash dashes to an allied champion and You and Me! attaches to them. This dash is Silence icon interrupted by Stun icon immobilizing effects. While attached, Yuumi follows her Anchor's movement, becomes Playful untargetable, (except from Turret icon turrets and in-flight Projectile projectiles targeting her) and casts her spells from the Anchor's position. The cooldown starts ticking down upon attaching to the first Anchor. You and Me! can be recast after 0.5 seconds of the attachment.

Change of Plan

Recast: Yuumi can switch her Anchor at no cooldown, and will detach automatically if her Anchor dies or under certain circumstances. If recast without a valid target, Yuumi will detach from her Anchor and dash up to 250 units in the target direction, putting the ability on cooldown.

You and Me! is placed on a 5-second cooldown if Yuumi is Stun icon immobilized or Grounded icon grounded.

"Book, meet new friend!"

Info
Notes
  • The ability name for the recast is Change of Plan.
  • You and Me! does not count as an ability activation for the purposes of on-cast effects such as Spellblade, charging Spellbinder item Spellbinder, and stacking Force Pulse Force Pulse.
  • Yuumi will automatically detach in specific circumstances:
  • The Dash dash has a maximum following range. If her target is too far away before the attachment, the dash is interrupted and You and Me! goes on cooldown.
  • If Yuumi is hit by a delayed area of effect ability (e.g. Chum the Waters Chum the Waters, Last Embrace Last Embrace, Time Bomb Time Bomb) or is emitting an aura effect (e.g. Wild Growth Wild Growth, Bami's Cinder item Bami's Cinder) and she attaches to an ally, the effect occurs from the Anchor's position instead.
  • Her Monster icon monster aggression transfers to the Anchor.
  • Enemies gain an assist on Yuumi if they damaged the Anchor.
  • Yuumi gains assists on champion Damage rating takedowns from her Anchor.
  • Yuumi will also become Guerrilla Warfare stealthed if her Anchor does, and can cast her own abilities without breaking the stealth.
  • Yuumi can channel the Eye of the Herald item Eye of the Herald while attached.
  • If Yuumi is on the blue team, she will remain attached on the southwest side; if Yuumi is on the red team, she will remain on the northeast. While channeling Final Chapter Final Chapter, she will be behind her Anchor.
  • Yuumi can dash to targetable Omen of Death zombie state allies (currently only Sion OriginalSquare Sion's Glory in Death Glory in Death), but she cannot stay attached for long.
  • Yuumi doesn't detach instantly when her Anchor dies. There's a small grace period in which she can recast You and Me! to attach to another champion without the Channeling icon channel.
  • The player's screen will briefly flash red if Yuumi is affected by a Stun icon immobilizing or Grounded icon grounding effect, or if she forcibly detaches from her Anchor.
  • The Anchor's health bar will have a different frame to indicate the attached status:
