So Zilean is a diffcult champion and i used him once for fun and i found him very op he carrys a 4v5 carry,support,and just being a **** planting bombs. The build should be all that he can lane or solo middle whatever he wants.

Zilean really doesnt need runes really but if you want to go to rank you would need some health Greater Seal of Health

OK the rest are just for some more cooldown and ap runes.
LIKE: Greater Seal of Health give more health better for him that way he might be focused.

Greater Seal of Cooldown Reduction for more cooldown get more Chronoshift and faster Rewind

Greater Glyph of Ability Power more ap... Even better

AINT A MAJOR IN RUNES NEVER FOUND INTERST IN IT. xD But thats what I use though

I used to use the old orignal king 9/0/21 but since it changed.... ITS STILL THE SAME.
Mental Force for ap Socery and the Arcane Knowledge for some ap!

The are for mana like Expanded Mind mediation

I got scout for more vision to put bombs more thats why i got Scout

The rest... COOLDOWN!!!

If your wondering what... Intelligence Mastermind

Doran's Ring
I started with Doran's ring because it gives good amount of ap and mana.

Than i quickly get Catalyst the protector because it give health and mana also everytime it levels up it gives more back which is good because Zilean passive is more Xp.

After that i get some boot finish my Rod of Ages and get Sorcerer's Shoes
than Morello's Evil Tome for cool down the rest are for supporting my team and some ap.

But you can also get these boots:
Ionian of ludcitiy=64 If you want more cool down.
or Boots of mobility=64

If you want to go all out ap this is what you should get.
Sorcerer's Shoes Rod of Ages Morello's Evil Tome
Rylai's Crystal Scepter Rabadon's Deathcap and a good ap item.

also you can do full support

Ionian of ludcidiy Rod of Ages Soul Shroud Shurelya's Battlesong
Will of the Ancients Rabadon's Deathcap

You can also get these items
Zhonya's Hourglass
Abyssal Mask
Void Staff

A SHORT DESCRIPTION
His passive is gaining more exp not exciting i know...

Time Warp it plant a bomb on a enemy champion after 3 seconds it deals damage.

Rewind let say you can now plant to time bombs at once cool?

Time Warp speed up ally or slow enemy

Chronoshift Revival uti.. Trick enemy to go for you at low health popp up uti than spamm you Time Bomb

I would quickly get Time Bomb and finish leveling it at 13 but i would get Rewind and Time Warp at 2 and 3 in that order. its like this

3 Time Bomb 2 Rewind 2 Time Warp

That why you can [rewind=64] [time bomb=64]] than
[[time warp=64] to catch up to him or ran away or just slow him.

thats the skill sequence i used.

I got Ignite because one it give more damage and a combo of Time Bomb x2 with Ignite is a good way to end a champion. Ghost i choosed because Time Warp and that gives a easy way to chase or run.
I would use Ghost Time Warp Ignite Time Bomb Rewind Time Bomb
Its a good finisher.

Other spells
Flash
Clairvoyance
Surge

Zilean is a werid support without heal or mana but the good thing is.. Revive. Its like having two op champions over again. In team fights you should be in the back revive and planting time bombs. If someone is about to die use his uti Chronoshift speed boost if someone is slow or need a boost to catch enemy Time Warp is your ability to use. A trick is to plant Time Bombx2 on him use Time Warp and let him get the enemy which would get a taste of the fury and bombs.

Farming with zilean is fun all you have to do is Time Bomb Rewind Time Bomb but make sure there in a group or just put one bomb at the very end and another on the oppsite side. Zilean time bomb has a count down a easy way to avoid that is put it on the lowest health minions .Thats about the only way to farm .

Pros
fun to use
count down to three when you see enemy running with low health and a bomb attach to them.
good uti
speed boosts

Cons
easy to take dowm
a little squishy
can easily lose his great burst of ap damge if lost of xp.

Zilean is just a fun and op champion that can be master in time. In the end Zilean might be a old man who is hard to play but once in a fight you better watch out....
