[Trigger] Map problem

[Serbianbeast]

Hi people. I've made a map, but it seems like there is a certain problem. When I use my custom made spell... piercing shot, game slows down a bit. When I use it again, it starts lagging even more, and after 3rd or 4th time I cast it it gets unplayable. Can any1 help plz? I'll upload the map and let you have a look. The thing I'm interested is in Night Archer's 3rd ability named Piercing Shot. It's in Night Archer folder in the trigger section.

Solved: what seems to be lagging is the shockwave ability which I made the spell from. Plz close this thread.
