Darius

Strengths

Decimate is a powerful harassment ability. Strike an enemy from maximum range for the greatest effect.
Noxian Guillotine does more damage the more attacks you can land prior to it. Use Noxian Might to deal maximum damage.
Darius benefits greatly from enhanced survivability. The longer you can prolong a fight, the more powerful he becomes.

Passive · Hemorrhage — Darius' attacks and damaging abilities cause enemies to bleed for physical damage over 5 seconds, stacking up to 5 times. Darius enrages and gains massive Attack Damage when his target reaches max stacks.
Q · Decimate — Darius winds up and swings his axe in a wide circle. Enemies struck by the blade take more damage than those struck by the handle. Darius heals based on enemy champions and large monsters hit by the blade.
W · Crippling Strike — Darius's next attack strikes an enemy's crucial artery. As they bleed out, their Move Speed is slowed.
E · Apprehend — Darius hones his axe, passively causing his physical damage to ignore a percentage of his target's Armor. When activated, Darius sweeps up his enemies with his axe's hook and pulls them to him.
Ultimate · Noxian Guillotine — Darius leaps to an enemy champion and strikes a lethal blow, dealing true damage. This damage is increased for each stack of Hemorrhage on the target. If Noxian Guillotine is a killing blow, its cooldown is refreshed for a brief duration.

A suggested 5-lane lineup built around Darius, based on hero partnerships and role synergy — not win rate.
