LoL Champion Build Guides: Yuumi

Yuumi fires a missile that deals 40 / 70 / 100 / 130 / 160 / 190 (+30% of ability power) (+2%-8% of the target's current health) in magic damage to the first enemy hit. If the missile is in flight for 1 second, it instead deals 45 / 85 / 125 / 165 / 205 / 245 (+40% of ability power) magic damage and applies a 20% slow to enemies for 1 second.

If Yuumi is Attached, she fires the missile from her ally's position and can direct the flight of the missile for up to 2 seconds.

Passive: While Attached, Yuumi and her ally share 12 / 14 / 16 / 18 / 20 (+12 / 14 / 16 / 18 / 20%) adaptive force, granting each other bonus attack damage or ability power (depending on which their ally has more of) equal to a percentage of their own attack damage or ability power (depending on which of the two is higher).

Yuumi starts the game with one point in You and Me!, while Prowling Projectile has 6 ranks.

Active: After a 0.25 second delay, Yuumi dashes to an ally champion and attaches to them. While Attached, she follows her ally's movement and is untargetable by everything except tower damage. Yuumi's abilities fire from her ally's location, and she can't attack enemies.

Yuumi can switch among her teammates without a cooldown. If Yuumi re-activates the ability without a valid target, she will detach from her ally and dash up to 250 units in the target direction. Yuumi also detaches automatically if the ally she is attached to dies. Immobilizing Yuumi places this ability on a 5 second cooldown. Silence doesn't count as an immobilizing effect that places You and Me! on a 5 second cooldown.

Yuumi heals herself for 70 / 94 / 118 / 142 / 166 / 190 (+40% of ability power) and gains 15% movement speed and 25 / 30 / 35 / 40 / 45% attack speed for 3 seconds.

While attached, the Anchor is targeted by the ability instead.

Mana Cost: 40 / 45 / 50 / 55 / 60 mana (+15% max mana)

Yuumi recoils and opens Book, launching 7 waves of 60 / 100 / 140 (+20% of ability power) magic damage over 3.5 seconds. Enemy champions who are hit by multiple waves take only 50% damage from any wave beyond the first, and they are rooted for 1.75 seconds when struck by three waves.

During Final Chapter, Yuumi can move and cast You and Me! and Zoomies.
