Io

Io the Guardian Wisp is a ranged strength hero who works best as part of a communicative team. With its support-oriented skill set, Io is able to share its strength 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, unlike other heroes, does not need to be facing towards a unit in order to attack, use abilities, or items. It still has a front, marked by an arc-like effect, and a back.
