Links to its allies to buff them
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.

Strategy
Tether breaks trees which is useful at making tree line paths or optimize farming routes.
Make sure to have spare consumables with you to keep your laning partner healthy.
Look around the map for opportunities to Relocate in and prompt your teammates to setup kills.
Past laning stage, you typically want to play with a core on your team who plays aggressively and utilizes their HP and mana pool while you buff them with Tether and Overcharge.
Avoid showing yourself at the start of the fight as you are number 1 target for opponents.
When using Relocate to save an ally consider relocating nearby to be able to re-engage faster.
You can use Relocate to push out a wave or rat a tower when not much is happening around the map.
Pick up Aghanims Shard later in the game to gain spell lifesteal and slow resistance through Overcharge for yourself and your Tethered ally.
Io is one of the best Cheese carriers in the game as you can extract double the value through the Tether.
Grab the healing lotus to have a burst of HP and mana regen for yourself and the tethered ally.
Past the laning stage, if you do not have fighting core hero on your team, look to play with your farming core to boost his farm and stack camps.
Counter Strategy
Someone should buy Spirit Vessel against Io to offset healing and regeneration.
Harass either Io or his laning partner, not both equally.
Relocate can be cancelled by disabling or silencing Io during channel time.
Focus Io in the fights as he's good at sustaining and saving his cores.
Gap closing items will help you get on top of Io.
Items that reduce healing and regeneration are great against Io.
Be careful about Io's ratting potential with Relocate.
Lore
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 existence together. It is only in the controlled warping of these electrical waylines 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.
