Hello guys this is my second guide,and i decided to do it about ryze because it is realy tough and great hero.

Background story:
The halls of traditional study were never for Ryze, who felt a more raw and primal connection to the magic of Runeterra than those who tried to teach him. As a young man, he travelled the world, seeking the wisdom of powerful hermits, witches, and shamans. When he had learned all he could, Ryze turned to seek the lost, forgotten, and forbidden knowledge in the world. This led him to an ancient form of spellcraft known as thorn magic. This art required Ryze to tattoo spells on his body, infusing his being with vast arcane power. His travels also brought him to the giant indestructible scroll he carries on his back. The purpose of the inscribed spell is a secret only Ryze knows. However, he claims it is an abomination, something that he must safeguard from the world. Today, Ryze has joined the League of Legends to study the magical creatures and powerful will-workers that fight there, in order to complete his exploration of mystical Runeterra.

''There is no doubt. Ryze is no longer a mage - he has become a creature of magic.''

Items:
Start with dorans ring and one health potion it gives you survivability to stay longer on your lane.Then buy boots of speed it will give you movement to chase/escape you dont need upgraded boots because you have ghost and flash.Then buy Catalyst it can help you a lot in fights when you get level you get health and mana it can save your life in early game.IF you want mana and mana regen you can go Tear of Goddess.Then buy Sorcerer's Shoes for magic penetration or if you are good farmed you can buy Archangel's Staff it realy great item it will help you with your "Q" skill in late game it will give +-1000 dmg,that item gives you a lot of mana some ability power and mana regen on beginning.After Archangel's Staff buy Rod of ages it gives you all you need and it is good to buy it in early game.It most of my games this items was enough to win,but if you still playing and you dont know what to buy,then buy these items: Rabadon's Deathcap --->Hextech Revolver---->Will of the acients-->Void Staff it should be enough to kill weak oponents in few seconds.

Will of the acients: Gives you and your team aura with spell vamp (on like lifesteal but you get health for spells not for atack) and some ability power.Can be useful if you are on low and running from someone just do combo on him and you will heal yourself.
Void Staff: Gives you magic penetration and ability power so you will cut your enemy.
There was a suggestion about Rylai's Crystal Scepter In my opinion its not bad item, gives you health to survive, ability power to atack and slows target. But i dont recomend to buy it because if you are focus something and you give it all you have it should die,if it not then you cant do anything to kill it even if it slowed.Its good for survivalability if you have enemy who is dangerous and focusing you then buy it instead will of the acients.

Gameplay:
Early
In early game try to avoid fights if you are on mid,you have weak your skills and you are very fragile and you have low health regen,try to just farm on items and sometimes harras enemy with "E" skill.If you are on dual lane and with you tank or dps let them go first and then jump there with "W" then "E" skills try to focus fragile heroes and harras them with "E".
Mid
Mid game is good time to gang,with your brutal ultimate and strong skills you become strong damage burst.Look where is low health enemies or where your team need help and go there.So you are there in bush and dont know what to do?Write tank to go first and start fight,when he do it rush there and kill all like rambo!Try to avoid deaths you are fragile so never Never NEVER go first to fight you are NOT chuck norris !!!
Late
So you should have Rod of ages,Archangel's staff,Sorceress Shoes and something eslse.Hide somewhere in bush and wait untill someone will start team fight.When there will be chaos (its usually in team fights) Flash there and chose most fragile enemy and go this kombo on him "R" ---> "W" ----> "E" ----> "Q" it should kill him and do a lot of damage to guys around him this will help your team mates a lot!!! Dont forget MAIN rule dont die dont go in team fights first you are not superman!!!

Good Luck And Have Fun Guys!!!
