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.
