Image delivery failed; source record unchanged.wisp_tether · #5485
Tethers Io to an allied unit, granting bonus movement speed to both. When Io restores health or mana, the tethered unit gains a portion of that amount. The tether breaks when the allied unit moves too far away, or Io cancels the tether. Tether slows enemies touching it.
Image delivery failed; source record unchanged.wisp_spirits · #5486
Summon five particle spirits that dance in a circle around Io. If a particle collides with an enemy hero, it explodes, damaging all enemy units in an area around it. Creeps take minor damage from touching a particle spirit, but do not cause them to explode. When its duration ends, any remaining Spirits explode.
