Passive: Hidden Weapons
The missile explodes and deals area damage to nearby minions and monsters when a standard attack hits an adversary. Fennik’s strike range is marginally greater than that of any other marksman with placement skills.
Skill 1: Thief’s Mark
Fennik leaves a mark on a foe or a structure, speeding up his attacks by 25%. After four seconds, the mark explodes around the target, causing 160/200/240/280/320/360 (+0.5 AD) physical damage to a large area. On targets that have been marked, Fennik’s standard attack deals an additional 160/200/240/280/320/360 (+0.5 AD) physical damage. The moment the mark reaches 4 stacks, it explodes.
Skill 2: Rolling Lightning
Rolling forward, Fennik does 80/90/100/110/120/130 (+0.7 AD) physical damage to foes in his path while slowing their movement by 50% for 2 seconds. Every 0.25 seconds, foes in the path take physical damage of 30/36/42/48/54/60 (+0.25 AD) from lightning traces.
Skill 3: Chain Hammer Cyclone
Fennik launches a flail to produce a thunder cyclone that lasts for 6 seconds and does 80/105/130 (+0.35 AD) physical damage to opponents every 0.5 seconds while slowing their mobility by 50% for 1 second. Additionally, enemies in the thunder cyclone’s center suffer double damage. The stack on Thief’s Mark will be activated by the thunder cyclone.
