Why this duo works

Zoomies(E) gives Hecarim bonus movement speed, which also increases his attack damage through Warpath(P). Yuumi can stay attached through Hecarim's charge and fear, so the pair arrives together with more damage and sustain.

Playing the duo

Yuumi's Zoomies(E) grants bonus movement speed to Hecarim, and Warpath(P) converts his bonus movement speed into attack damage.

Yuumi's You and Me!(W) keeps her attached through Hecarim's Devastating Charge(E) and Onslaught of Shadows(R), letting her carry her shield and healing into his engage.

How to play as Hecarim

Tell Yuumi before you charge in and let her attach first; her movement-speed buff increases your Warpath(P) damage as well as helping you reach the target.

How to play as Yuumi

Attach to Hecarim before he starts Devastating Charge(E), then use Zoomies(E) to increase his approach speed and damage. Keep Final Chapter(R) ready for the fight after his fear lands.
