Increases experience gain of all allied champions by 8%. This bonus is unavailable while Zilean is dead.
Heightened Learning is a global aura.
Summoners with experience gain pop-ups should note that the numbers displayed reflect the pre-modified experience earned.
Cost: 70 / 85 / 100 / 115 / 130 mana
Active: Zilean places a ticking time bomb on any unit, allied or enemy, which detonates after 4 seconds, dealing magic damage in a 330-unit area. Bombs will detonate immediately if the holder dies or if another bomb is placed on them.
Spell shields will only block the placement of a bomb. Spell shields will not block the detonation nor the damage in any circumstance.
Time Bomb will cancel an enemy champions recall.
If a bomb is placed on a stealthed ally, it will not be visible to the enemy team.
A ticking bomb will draw turret aggro.
A ticking bomb does not grant an assist if the target dies before it explodes.
A bomb will detonate an enemy Zilean's bomb when placed on the same unit. This does not prevent the enemy's damage.
If a bomb carrier takes lethal damage and triggers a revive effect, such as Chrono Shift or Guardian Angel, the bomb is removed like all other debuffs.
A ticking bomb will still detonate even if the carrier becomes untargetable. The carrier will still take damage unless they are also invulnerable, through effects such as Frozen Tomb or Zhonya's Hourglass.
Various champions that have abilities that make them untargetable can prevent the damage from Time Bomb, such as Vladimir, Elise, Fizz, Lissandra, Shaco, Fiora, Zed, Master Yi, or Maokai.
Cooldown: 18 / 15 / 12 / 9 / 6
Cost: 50 mana
Active: Zilean reduces the cooldowns of all of his other abilities by 10 seconds.
Rewind cannot be learned at Level 1. That would be as silly as an armored bear.
Cost: 80 mana
Active: Zilean bends time around a champion, slowing an enemy champion or increasing an ally champion's movement speed by 55% for a short time.
Duration: 2.5 / 3.25 / 4 / 4.75 / 5.5
Time Warp can target a single champion, either ally or enemy.
Cost: 125 / 150 / 175 mana
Active: Zilean places a protective time rune on an allied champion for 7 seconds. If the target takes lethal damage during that time, they will be placed in stasis - making them untargetable and invulnerable. After 2 seconds, the target is revived with a set amount of health.
Health Regained: 600 / 850 / 1100 (+ 200% AP)
Chrono Shift can target a single allied champion.
The rune will not activate if the holder is killed by the Nexus Obelisk.
