Welcome to my 1st ever guide for LOL and it's for one of my favorite champs Darius......
1st of all forgive my bad designing coz actually i am not good in that (not good in writing
those chapters).
2nd feel free if u have any idea about my guide ... just till me.

There is no greater symbol of Noxian might than Darius, the nation's most feared and battle-hardened warrior. Orphaned at a young age, Darius had to fight to keep himself and his younger brother alive. By the time he joined the military, he had already developed the strength and discipline of a veteran soldier. The first true test of Darius's resolve occurred in a crucial battle against Demacia, where the Noxian forces were exhausted and outnumbered. Darius's captain called for his troops to retreat, but Darius refused to accept such an act of cowardice. Breaking formation, Darius strode towards the captain and decapitated him with one sweep of his gigantic axe. Both terrified and inspired, the soldiers followed Darius into battle and fought with incredible strength and fervor. After a long and grueling battle, they ultimately emerged victorious.

Seizing momentum from this victory, Darius led his now fiercely loyal troops in a devastating campaign against Demacia. After proving his power on the battlefield, Darius turned his gaze homeward. He saw a Noxus riddled with weakness, where greedy, complacent nobles drained the nation's strength. Seeking to restore his country to greatness, Darius took it upon himself to reshape the Noxian leadership. He identified weak figureheads and violently removed them from their positions of power. Many in Noxus saw Darius's cull as an attempt to seize power, but he had a different plan for the throne. He had been watching the rise of Jericho Swain with keen interest. In Swain, Darius saw a leader with the mind and determination to bring Noxus to glory. Now allied with the Master Tactician, Darius works to unite the nation behind his vision of true Noxian strength.

"A united Noxus could control the world - and would deserve to." - Darius

PROS:

- Large amount of damage with just 1 or 2 items (not item dependant).
- Fun to play.
- Various play styles (Full AD - Full Tank - Offtank).
- One of the best ultimates in the game.
- Low mana cost.
- Kinda hard to be countered.
- Very easy to play and master.

CONS:

- Easly Kited (specially by those solo top ranged champs).
- If you started to do well you will get focused.
- Vulnerable to early ganks.
- No Natural tankiness , susatin.
- No escaping abilities (except Ghost & Flash)

Hemorrhage

(Passive): I consider this skill as a mini Ignite as it apply a damage over time (5 sec.), it also give you 5% movement speed per each bleeding enemy champion, as well it's very useful for Crippling Strike as it reduces its cooldown by 1 sec for each stack of Hemorrhage on the target, and usefull too for Noxian Guillotine (Explained Below).

Decimate

(Q): The main harassing skill for Darius..... actually i like it as it does a high amount of damage specially at the blade of his axe , useful in team fights and a very good farming skill.

Crippling Strike

(W): In my opinion this is the main reason that makes 1v1ing Darius is hard as it prevent the enemy from escaping (by slowing) , dealing a good amount of damage and reduce attack speed too.

Apprehend

(E): This skill is similar to Blitzcrank's Rocket Grab , the difference is that Apprehend can pull multiple targets and has low range......this skill is very useful for Darius as it gives him 25% armor penetration at max level ..with this skill you will not need to build armor penetration so much.

Noxian Guillotine

(R/Ulti.): This is the reason that makes Darius so famous and lethal as it has 680 base damage and can be in increased by 20% per stack of Hemorrhage... and above that it's cooldown refreshed for 12 sec. if u kill a target with it (easy way to get a PENTAKILL).
