As hecarim, Hecarim's ability to deal damage will skyrocket during this phase of the game. He will also be quite tanky due to his items and stats, which means that he will be a powerhouse of consistent DPS.

Once he gets 3 points in his Ultimate t, no enemy backline will be safe anymore. So Hecarim should use the fog of war and sit on the top side of the enemy Jungle and wait to kill any wandering enemy champion.

Once his h and W get maxed out, he will be almost unkillable as long as he is mobile and manages to stick to his target. CC is his worst enemy, so some tenacity will help him a lot.
