Hecarim

Strengths

Spirit of Dread restores Health when nearby enemies take damage, including damage dealt by allies. Cast this during a large fight to maximize Hecarim's survivability.
Devastating Charge deals more damage based on the distance traveled. Try using Onslaught of Shadows or Summoner Spells such as Ghost or Flash to maximize this damage.

Passive · Warpath — Hecarim gains Attack Damage equal to a percentage of his bonus Move Speed.
Q · Rampage — Hecarim cleaves nearby enemies dealing physical damage. If Hecarim damages at least one enemy, he increases the damage and lowers the cooldown of subsequent Rampages.
W · Spirit of Dread — Hecarim gains Armor and Magic Resist. Hecarim deals magic damage to nearby enemies, and gains Health equal to a percentage of any damage those enemies suffer.
E · Devastating Charge — Hecarim gains increasing Move Speed and can move through units for a short duration. His next attack knocks the target back and deals additional physical damage based on the distance he has traveled since activating the ability.
Ultimate · Onslaught of Shadows — Hecarim summons spectral riders and charges forward, dealing magic damage in a line. Hecarim creates a shockwave when he finishes his charge, causing nearby enemies to flee in terror.

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