Zilean Rework [It's really time themed, I promose ;)]

Passive - Chronosorcery Every 5 minutes in game, Zilean gains bonus AP. Additionally, after a certain point in the game Zilean's spells gains a bonus effect. (Should be shorter in ARAM, DOM, and TTL)

Chronosorcery Bonus at 5 minutes in game: Instantly gains a charge of Rewind and at every 30 seconds in game. Zilean can activate a skill that is on cooldown by consuming a charge of Rewind. Holding a charge still counts towards the countdown until the next charge. Max 1 charge. Rewind only reduced the cooldown of R by 10 seconds. (Ex. At 5:29, Zilean consumes a charge on Q, then at 5:30 Zilean immediately gains a new charge. However, if you did not use the charge at 5:29, then at 5:30 the new charge replaces the old one.) Additionally, after every 5 minutes in game, Zilean's spells or stats gains a bonus.

Chronosorcery Bonus at 55 minutes in game: Now gains charges of Rewind every 10 seconds instead.

Q - Time Bomb Fires a ball of compressed time at target enemy or ally and tags onto them for 4 second and then explodes, dealing AoE damage. Enemy units can block this skill and it tags onto them instead. Ally cast cannot be blocked. (Think Cait ult or Pix, but enemy minions and jungle monsters can block it as well. Same mechanics as Zilean's live Q.) Every additional Q within a moderate duration deals less damage. Chronosorcery Bonus at 15 minutes in game: The damage reduction of each additional cast is removed, and the projectile's speed is increased.

***W - Time Bubble *** Creates a bubble at target location for a short duration. Enemy projectiles caught in the bubble will have their travel speed reduced by 80% while inside the bubble. Enemies while inside the bubble are slowed and gain stacks of Chronodisplasia every 0.5 seconds, and Zilean's damaging attacks will consume the mark to deal bonus damage per mark. The bubble duration scales with rank. Chronosorcery Bonus at 25 minutes in game: The bubble now completely freezes the projectile for the duration of the bubble, and the slow amount is increased while enemies are also slowed for an extra second upon exiting the bubble.

E - Time Accel/Decel Ally Cast - Target champion's animation speed are increased by 100% for a few seconds. This effect ends prematurely if Zilean gets damaged within the duration. (Ex. Ezreal normally takes 1 sec to jump up and fire his ult. Now it takes 0.5 secs to complete that action.) [This effects the cast time of spells, channel duration, attack speed, movement speed, and also their projectile speed.] Enemy Cast - Target champions animation speed are slowed by 50% for a few seconds. This effect ends prematurely if Zilean gets damaged within the duration. Chronosorcery Bonus at 35 minutes in game: Now grants a decaying speed buff on allies and a slow on enemies for a moderate duration. This speed modifier duration is halved if Zilean takes damage. (The full duration of the decaying speed modifier should be the same as the cooldown of E when you have 40% CDR in order to retain Zilean's perma-haste/slow)

R - Chronoshift Marks an ally champion with a Revive rune for 2 seconds. If they die during the duration of the mark, they will be revived. The Revive rune changes into a Rejuvenation rune after 2 seconds, granting movement speed and healing them over 5 seconds. Chronosorcery Bonus at 45 minutes in game: For 1 second after the Revive rune is consumed or wears off, any damage and CC dealt to the champion is delayed for 1 second. The heal and revive amount is also increased.

My goals in this rework are to: Implement more time theme into Zilean's spells, make Zilean's spells have more interesting play patterns, open up more decision making, and also make it fun and interactive to both the Zilean player and the opponent.

Here's the link to my old rework from a while ago. It includes my analysis on the pros and cons of Zilean, and what I think his core identities are.

Thank you very much for going through my rework. If you liked this, please upvote. If you disliked this, feel free to downvote. As always, I'll appreciate any positive feedback and also constructive criticism, as well as any other suggestions and ideas.

Have a great day, summoners! :)
