Killing an enemy unit grants a stack of Excitement. When Shairvante gains a certain amount of Excitement stacks, he gains bonus spell and auto-attack effects (2 stacks for large minions and monsters, 10 stacks for a champion).
50 Stacks: Auto-attacking reduces all cooldowns by 0.5 seconds; critically striking reduces cooldowns by 1 second instead.
80 Stacks: Shairvante converts 25% of his bonus AD into bonus attack speed.
120 Stacks: Critically striking grants Shairvante an additional 30% critical strike damage for 2 seconds.
180 Stacks: Shairvante converts 20% of his bonus movement speed into bonus critical strike chance.
250 Stacks: Shairvante's spells can also critically strike, dealing 200% of their base damage and scaling. If this does happen, the cooldown of the spell that critically striked is reduced by 2 seconds.
Critical strikes from spells do not interact with Shairvante's critical damage modifier, but instead only interact with his critical strike chance.
If a spell critically strikes, it will not reduce all of his cooldowns by 1 second.
STATIC COOLDOWN: 10 / 9 / 8 / 7 / 6
Active: Shairvante deals physical damage to all enemies around him and then gains attack speed based on how many enemies he hit (max. 5 enemies can grant a single attack speed bonus) for 1.5 seconds. Striking one enemy unit grants attack speed for double the duration, and if Shairvante uses Quickslash again before this duration ends and hits one enemy unit again, he stacks the attack speed buff with the previous (max. 5 gained this way).
Spell shields will block the damage but will not prevent Shairvante from obtaining the attack speed buff (If Overpower has been used for Quickslash, spell shields will also block the attack speed reduction).
Quickslash has no cast time and does not interrupt Shairvante's previous orders.
COOLDOWN: 12 / 11 / 10 / 9 / 8
Active: Shairvante deals physical damage to all enemies in a line in front of him and slows all enemies hit for 0.75 seconds.
Only the first strike can critically strike and will deal double damage. The 2nd strike can critically strike only after Shairvante has reached 250 Excitement stacks, since it's a spell-given on-hit effect. Both strikes will apply lifesteal and on-hit effects.
Note however, that only the first attack will consume on-hit effects that apply only for a single hit (For example, Sheen'sSpellblade).
Riposte will only parry the first attack, as well as Aegis Protection. If so, Shairvante will gain a shield amount equal to the damage dealt by only one attack, but only if Shairvante has used Overpower for High-Speed Combo.
Neither attack will land (or grant a shield value if Shairvante has used Overpower for High-Speed Combo) if Shairvante'sblinded.
