Zilean Rework Idea
Zilean hasn't been the best of champions for a while, and with his outdated kit, he could use some updates. This rework attempts to fix that.
Passive: Time in a Bottle- Zilean takes 20% reduced damage, but all of the damage he takes, he stores it in a bottle. The next time he uses an ability, he takes magic damage equal to the amount of damage stored in the bottle. This empties the bottle.
Q: Time Bomb- Zilean creates a trap on the ground that detonates after 1 minute, dealing 80/120/160/200/240(+60% AP) magic damage to enemies near it. If Time Bomb kills an enemy, its cooldown is reset. Cooldown: 30 seconds
W: Rewind- Zilean rewinds an enemy, reverting their health back to what it was 4 seconds ago. Using this doesn't activate Time in a Bottle, but increases the amount of damage stores in the bottle by 100/90/80/70/60%. Cooldown: 20 seconds
E: Time Warp- Zilean warps time at a location, slowing enemies in an area by 22/25/28/31/34%. The slow zone lasts for 2 seconds. Cooldown: 10 seconds
Ultimate: Chronoshift- Zilean places a protective time rune on an enemy, granting them Zilean's passive for 7/9/11 seconds. (That ally takes 20% reduced damage, but stores damage they take. If they use an ability, they take that damage again.) Cooldown: 100 seconds
The point of this rework was to increase Zilean's teamfight and protective potential, while updating his abilities to give them more effects. Reply with any changes you'd make!
