Since everyone is guessing what Zyra’s abilities are guess it’s time to for me to take a guess as well.
Passive - Zyra is filled with the mending power of nature. All nearby champions passively regenerate X% hp ever 5 secs.
Rampant Growth – Zyra throws seeds onto the ground that will grow rapidly snaring all enemies caught in the AoE while dealing damage over time for the duration of the snare.
Barkskin – Zyra shields herself with the forces of nature for X amount of damage. She is healed for the X% of the damage absorbed.
Ivy Lash – Zyra summons plants to lash at her enemies dealing damage on contact and also damage over time via bleeds or poisons.
Nature’s Wrath – Summons a circle of trees in target area. 2 tree erupt from the earth on opposite ends of the circle every .25 seconds dealing damage and knocking any enemy positioned above them into the air. All enemies are trapped inside, upon reactivating Nature’s Wrath all the trees collapse into the center dealing X damage to all enemies trapped inside.
sounds too much like maokai to me. at least with the ulti. remember that he said she was completely unique
