[REQUEST] Special Effect, Spinning blades

I am trying to create a spell where 4 blades appear around a character and spin.

I am currently doing this by creating a dummy, attaching a static effect, and rotating the dummy unit. This isn't very effective and requires more overhead than a simple special effect.

Characteristics:
A single special effect mdx:
4 blades, curved, like in the screen shot. Rotating at a fast, consistent speed, the blades should look like they are rotating fast but slow enough that you can tell what direction they are rotating in. They should fit around a villager like in the screen shot.

I hope this is simple and do-able.

glaive projectile? only three but should work...

I guess that is alright. It's a bit shorter than I would have liked. I suppose I can play with scale somehow.
Edit: I decided this was good enough. Thanks for the heads up Arbitor.

i don't have Wc3 installed but you could do something similar to what you were talking about above with the glaive projectile, only you wouldn't have to rotate it. be simpler to just go with it as is though.
