I've been playing IO (guradian wisp) for a while. Recently I visited playdota.com and I was quite confused when I found out the mechanism behind its skill Spirits:

  • Io summons 5 ancient Spirits over the course of 4 seconds; the Spirits dance around Io in a circle to protect him. If an enemy hero moves close enough to touch a Spirit, the Spirit releases its life energy in a burst, damaging all enemies in a 300 area of effect. Non hero units only take minor damage upon touching a spirit and do not cause them to explode.

I remember initiating the spirits when an enemy was quite close to me but

had I actually dealt any damage to the enemy before the 5 spirits were all summoned?

During the 4seconds initiation/summoning time, no spirit seems to "release its life energy in a burst" when encounters an enemy hero.

  • strange. the spirits should blast immediately after they spawn. normally you do not have to wait for all spirits to be created. maybe you did not hit the hero?

as soon as the spirit starts hurling around IO, if it hits a hero, it WILL explode and cause damage.
