First Cast: Vi begins channeling, increasing the damage and range of Vault Breaker over 1.25 seconds. Vi can still move while channeling, but she cannot attack or use her other abilities, and her movement speed is slowed by 15%.
Second Cast: Vi dashes towards the cursor's location, dealing physical damage and applying Denting Blows to all enemies hit. Vi stops upon colliding with an enemy champion, knocking it back. Vault Breaker deals 75% damage to minions and monsters.
Although Vi cannot use her own abilities while charging, she can still use summoner spells and item actives.
If Vault Breaker is charged for at least 4 seconds, the channel will cancel and will go on full cooldown. Unlike similar channeled spells such as Varus'sPiercing Arrow, Vi is not refunded mana for cancelled attacks.
However, if the channel of Vault Breaker is interrupted in some way (such as with hard crowd control), Vault Breaker instead goes on a short 3 second cooldown and does refund half of the mana cost to Vi.
Non-champion enemies hit by the dash are pulled in towards Vi instead of being knocked away.
Passive: Every third attack on the same target deals additional physical damage equal to a percentage of the target's maximum health, reduces the target's armor by 20%, and grants Vi bonus attack speed for 4 seconds. Denting Blows deals a maximum of 300 damage against minions and monsters.
Bonus Physical Damage: 4 / 5.5 / 7 / 8.5 / 10% (+ 1% per 35 bonus AD)of target's max health
Unlike most forms of on-hit physical damage, Denting Blows' bonus damage does not apply life steal. This is a special case, perhaps to prevent abuse or for flavor. The triggering attack will still apply life steal.
Denting Blows' bonus damage does not affect structures.
Critical strikes do not interact with Denting Blows' bonus damage.
Unlike the similar ability Vayne'sSilver Bolts, attacking or using abilities on different targets will not remove Denting Blows' stacking debuff.
Denting Blows' attack speed buff will not stack with itself with repeated applications, nor will it stack from applying it on multiple targets in quick succession.
Cost: 60 Mana + 1 charge
Active: Causes Vi's next basic attack to deal increased physical damage, hitting all enemies in a cone behind the target. Vi gains a new charge of Excessive Force periodically (this reload time is reduced by cooldown reduction) and can hold up to 2 charges at once.
