Io

Io the Wisp is a highly unique Ranged Strength Hero who works best as part of a communicative team. With his support-oriented skillset, Io is able to share his strength through Tether and Overcharge, harass enemy Heroes out of the lane with Spirits, and materialize himself 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 Wisp features one of the highest skill ceilings in the game.

Tips

 * Tether can be used on allied heroes to get to their side with great speed, as it latches from a considerable distance.
 * Approaching a confrontation from behind will allow for easier use of Tether's stun. Positional items are also useful for this.
 * Spirits requires much practise and focus to control, and due to its high mana cost it is not advisable to use it frivolously.
 * Building Heart of Tarrasque or other HP regen items will allow for much more liberal use of your Overcharge.
 * Should an emergency arise, Io may Tether to a wounded ally and then Relocate to the fountain to heal both Io and his ally.
 * You can also save the life of a crucial allied hero with this method, but it will often result in your own inevitable death when Relocate forces you to return to your original location. Be sure to un-Tether your ally before you return.
 * The inverse of this can also work; Relocate from your fountain to to the crucial ally and Tether them to bring them back. This is not always viable however, as it entails the 12 second discrepancy between Relocations.

Trivia

 * This Hero is made of particles without any visible mesh.
 * Wisp does not have a voice, unlike any other hero in the current game, and only makes ghostly noises.
 * Though genderless, Io is usually referred to with male pronouns; likely because his original Warcraft 3 model had a male face visible (and because of the ambiguity of the English pronoun "it").
