Notes
Io does not need to turn to perform actions. Io can attack, move, cast abilities, and cast items without waiting for the turn to occur first. This is a unique and innate trait of Io. Io still retains a turn rate and a front/back for the purposes of directional input, and still attempts to turn after an action is performed.

Io Io, the Wisp[edit]

Recommended Roles
Support Escape Nuker

Io is everywhere, and in all things. Denounced by enemies as the great unmaker, worshiped by scholars as the twinkling of a divine eye, this strange Wisp of life-force occupies all planes at once, the merest fraction of its being crossing into physical existence at any one moment.

Like the great twin riders Dark and Light, and yet another ancient traveler whose true history is lost to the ages, Io the Wisp is a Fundamental of the universe—a force older than time, a wanderer from realms far beyond mortal understanding. Io is nothing less than the sum of all attractive and repulsive forces within the material field, a sentient manifestation of the charge that bind particles together. It is only in the controlled warping of these forces that Io's presence can be experienced on the physical plane. A benevolent, cooperative force, Io bonds its strange magnetism to others so that the power of allies might be enhanced. Its motives inscrutable, its strength unimaginable, Io moves through the physical plane, the perfect expression of the mysteries of the universe.

Allied Units
Io tethers to an allied unit, granting both Io and the tethered ally bonus movement speed. While tethered, the health and mana Io regenerates is restored to the tethered ally. Any enemy unit that crosses the tether is slowed. Io may also cancel the tether at any time with the
  ability.

The benevolent touch of Io brings strength from between the planes.
Notes
  • Ally regeneration is based on Io's current regeneration.
  • Io's movement speed is set to match the the tethered ally's movement speed.
  • Enemy units may only be slowed once per cast of tether.
  • The tethered unit will only gain hp and mana if Io is gaining hp and mana; They will not regenerate if Io is full.
  • If Io and the target allied unit are further than 700 range apart at time of ability use, Io will slingshot rapidly towards the allied unit to a distance of 300 range. If this slingshot occurs, trees at the destination around Io will be destroyed.
  • Tether grants Aghanim's Scepter bonus to the tethered hero.
  • Attacking the tethered ally's target is passive and does not interrupt Io.

Notes
  • Spirits spawn one by one over 4 seconds and will initially spawn 150 units away.

  • If Spirits spell duration runs out or Spirits is recast, any spirits that are still circling Io will explode at their present location.
  • The spirits complete a revolution every 2.3 seconds regardless of distance from Io, meaning that spirits move more quickly when further from Io.

General Strategy[edit]

Io has a talent for making allies more effective. A powerful companion, the wisp's tether speeds allies and stops enemies. Capable of linking to and teleporting across the battlefield with an ally, Io can make a dangerous ally even deadlier.
