Originally nothing more than a lowly spirit of the trees, Io dwelt peacefully amongst his kind in the Great Forest. As the Great War spread across the land the creatures of the forest were forced to defend their home. The desire to protect his kin awoke power in Io he had not known he possessed. He discovered he was able to connect his life force to another creature to strengthen them or help them flee by instantly transporting them out of harm. Io became known amongst his people as the Guardian Wisp, a protector of the Spirits. All other spirits swore to assist him and can be summoned to his side to aid him in his battle. Uninterested in the battle between the Sentinel and the Scourge, Io fights only to protect his people.
|The Guardian wisp links himself to a target ally hero, allowing the target to gain any positive buffs Io has. Both units also gain extra movement speed, and any enemy units who come into contact with the tether will be stunned and take magic damage. The tether will break if it stretches too far. Lasts 12 seconds.|
|Io summons 5 spirits around him, which will explode if an enemy hero comes into contact with them. If an enemy non- hero unit comes into contact, it'll only be damaged slightly. Io can make the spirits circle around him in a wide area, or contract to spin around him.|
|The Guardian Wisp charges himself with excess energy, gaining additional attack speed and grants damage reduction. However, it will also drain 2.5% of his maximum health and mana every second. Any tethered unit will gain the positive buff.|
Io teleports both himself and his tethered ally to a target destination after a brief delay. After 12 seconds, both heroes return to their original spots.
