Io

Io, the Wisp, is a ranged strength hero who works best as part of a communicative team. With its support-oriented skill set, Io can share its healing and buffs through Tether and Overcharge, harass enemy heroes out of the lane with Spirits, and materialize itself and an ally anywhere on the map with Relocate.

Gank enemy heroes, push undefended lanes, save teammates from deep within enemy territory—the possibilities are endless, and Io features one of the highest skill ceilings in the game.

Io's facing direction is marked by an arc-like effect.
