Hi,
1. Multicast + Power Shot (from windrunner): Dark Seer was the hero model. When the skill mc'ed 3 times, the arrows shot in 3 different directions which completely ruined that build.
2. Mc + Ice Blast: When mc'ed, Ice Blasts were not released at the same time so they did not hit the same area.
PS, it was a while ago so I didn't have the replay saved.
Thank you!
