    • This also means that the maximum damage and heal are reached after 1.7 seconds of channeling.
  • Checks the current daytime upon releasing the wave.
  • During the channeling, the spell spawns vision fields in a line in front of Ezalor.
    • The vision fields provide 375 range flying vision and last for 10.34 seconds each.
    • The first vision field spawns 150 range in front of Ezalor. The following ones spawn 150 range away from the previous vision fields.
    • The vision fields are spawned in 0.5 second intervals, starting 0.5 seconds after channeling start, resulting in up to 4 fields.
    • When the channeling gets canceled, it stops spawning vision fields. This does not affect the travel distance of the wave.
    • When fully channeled, all vision fields together reach up to 825 range away with their vision.
  • The Spirit Form buff is granted by Aghanim's Scepter icon.png Aghanim's Scepter. It has only visual purposes and does nothing.
