Bop 'n' Block
STATIC COOLDOWN: 18 − 6 (based on level)
Bop 'n' Block

Innate: Periodically, Yuumi's next basic attack against an enemy Champion icon champion becomes Excessive Force 2 unstoppable, gains Range icon 50 bonus range and becomes a Projectile non-projectile. This attack restores 25 − 100 (based on level) (+ 8% maximum mana) Mana icon 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.
  • Although the shield doesn't expire, it will never stack with itself.
  • Considering Yuumi's base mana, Bop 'n' Block's mana restore is increased by at least 32 − 93.2 (based on level).

You and Me!

Active: After a 0.25-second Channeling icon channel, Yuumi Dash dashes to the target 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, is 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 completing the Channeling icon channel. 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 250 units in the target direction, putting the ability on cooldown.

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

 
Yuumi 135
"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 can channel the Eye of the Herald item Eye of the Herald while attached.
  • The ability power multiplier is Additive stacking icon additive with other ability power multipliers, like from Rabadon's Deathcap item Rabadon's Deathcap or Dragon Slayer buff Infernal Might.
  • The bonus attack damage multiplier is Additive stacking icon additive with other sources of bonus attack damage multipliers, like from Unseen Predator Unseen Predator and is Multiple stacking icon multiplicative with total attack damage multipliers, like from Whisper Whisper or Dragon Slayer buff Infernal Might.
  • Yuumi will automatically detach in the following 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.
  • While attached to the Anchor, Yuumi is considered in being at her Anchor's position, regardless of where she is visually placed near them. For example, Turret icon turret shots will appear as if they were hitting the Anchor, but in reality they're actually hitting Yuumi.
  • 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.
  • 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:
