P: Vicious Venom
Hitting an enemy with a spell adds one stack of Vicious Venom. Each stack of Vicious Venom deals 3-10 (+0.05 AP) magic damage and slows the target 4/6/8/10%, stacking up to 4 times. Lasts for 3 seconds.
Q: Noxious Blast
After a brief delay, target area erupts and deals magic damage to all enemies in the area. If Cassiopeia hits an enemy champion with this ability, she briefly gains movement speed.
W: Miasma
Launches a spray of venom in an arc that lasts for 5 seconds. Enemies in the area on impact are knockdown snared for 1 second. Enemies within the area are grounded, take damage and gain 1 stack of Vicious Venom each second.
E: Twin Fang
Empowers Cassiopeia's next basic attack; gaining range, speed and dealing additional magic damage. If this attack kills or the target dies while in flight, its cost is refunded and the cooldown reset. If the attack hits an enemy affected by Vicious Venom, Cassiopeia is healed based on Twin Fang rank and stacks of Vicious Venom.
