What is Zena?
Zena is an assassin the uses dual blades to fight, however, her main damage source is her cursed attacks. These will be explained more in the kit. Zena, on a physical scale, is a embodiment of purifying the living through death. Just like Kalista is the embodiment of vengeance.

Abilities
Passive: Death's Veil
After Zena kills or assists someone in killing, she gains a temporary veil that makes her invisible. While in her veil, she gains increased movement speed towards enemy units. Upon using an ability or autoattack, she will deal 50-250 bonus magical damage.

Q: Purity's Curse

Mana: 80 (all levels)
Zena marks a target with a curse. The curse will corrupt a target's health over 5 seconds worth 50/100/150/200/250 (+60% AP) magical damage. The longer the curse is on a target the more Cursed Health they will have. The curse is broken once Zena attacks her target. At that point, the current Cursed Health will pop for double it's current value. The curse will disappear after 1 second of not being acted on after the original 5 seconds.
Ex. Target has 100 cursed health. Zena uses an ability or aa's them. The curse will pop for 200 damage plus 60% of Zena's ability power.
