The damage type that Zilean deals is mostly Magic Damage.
Zilean's damage type breakdowns as follows:
Zilean stores time as Experience. When he has enough Experience to finish an ally's level, he can right-click them to impart it. Zilean receives as much Experience as he gives. Cannot be used in combat.
Zilean tosses a time-delayed bomb to a location. The bomb sticks to the first unit which comes within a small area around it (prioritizes Champions). After 3 seconds it detonates, dealing 75/115/165/230/300 (+90% bonus Ability Power) magic damage to all surrounding enemies. Placing two bombs on a unit detonates the first bomb early, stunning all enemies in the blast for 1.1/1.2/1.3/1.4/1.5 seconds.
Reduces Zilean's other basic spell cooldowns by 10 seconds.
Zilean increases an allied champion's Movement Speed, or slows an enemy champion, by 40/55/70/85/99% for 2.5 seconds.
Zilean marks himself or an allied champion with a protective time rune for 5 seconds. If the target would take lethal damage, they are instead transported back in time, regaining 600/850/1100 (+200% bonus Ability Power) Health.
