Zyra passive concept

Rize of the Thorns (360 second cooldown) Upon death, Zyra reenters her plant state. After a 1 second delay, she becomes immobile and untargetable for up to 10 seconds. While in this state, her basic attacks are buffed to have 700 range, and deal 12/13/14/15/16/17/18/19/20/21/22/23/24/25/26/27/28/29/30 (+10% AP) bonus magic damage on hit. Her abilities are replaced by Draining Thorns After a 1 second delay, deal 200-400 (+20% AP) true damage in a target area. If an enemy champion is killed by this, you will revive.

If Zyra dies while Rize of the thorns is on cooldown, her autos are disabled while dead, and she cannot revive, but Draining Thorns may still be cast.

Rize of the Thorns has its cooldown reduced by 2 seconds each time a plant is grown.
