Additionally, Caitlyn gains 15% bonus attack speed and her regular basic attacks each generate a stack of Headshot, doubled when attacking from brush, granting her next basic attack the same bonus physical damage at 6 stacks, though this does not benefit from bonus range nor is it consumed on other instances of Headshot.
Active: After 1 second, Caitlyn fires a projectile in the target direction that deals physical damage to the first enemy it passes through, after which it expands in width but deals only 67% damage to all enemies it passes through thereafter.
Passive:Caitlyn periodically stores a charge of Yordle Snap Trap, up to a maximum amount stored at once.
Maximum Traps: 3 / 3 / 4 / 4 / 5
Active:Caitlyn sets a trap at the target location that arms after 1.1 seconds and lasts up to 90. After the maximum amount of traps is laid down, deploying another immediately destroys the oldest one.
Enemy champions who step on a trap set it off, rooting them for 2 seconds, during which they take increased damage from Headshot, grant true sight of themselves for 9 seconds, and become immune to Yordle Snap Traps for 4 seconds while they remain in the area.
If Caitlyn loses sight of her target before she locks on The ability cancels but neither does it go on cooldown or consume any mana.
Ace in the Hole grants true sight of the target while locked on, and becoming stealthed during the channel will have no effect as the missile will follow and can still hit stealthed champions, effectively revealing their position.
Clones will intercept the missile as they are classified as champions for targeting purposes.
Once Caitlyn has started channeling, she is unable to cancel the ability herself.
This is unlike many other channeled abilities, such as Malzahar canceling Nether Grasp by being commanded to move.
Ace in the Hole will be canceled and put on a 5-second cooldown (but not refund the mana cost) if the target dies or becomes untargetable during the channel.
If the target dies after the bullet has been fired it will continue toward their corpse and can still be intercepted. The ability will then go on full cooldown.
The missile will continue to follow untargetable champions but will fizzle upon reaching them, unless they become targetable before it would hit.
