Terror Spell

What do you think of this spell? It makes units flee from caster for 5 seconds slowing their movements. Thanks.

Shouldn't it rather speed up their movement?

Uhm, actually no because it would become useless^^ It's a sort of stun spell. I forgot to upload the map, now it's online.

Yeah it could be a useful spell if your pretty much surrounded and need an escape. That happens to me way too much b/c of lag or I'm not watching and I get surrounded and killed! Anway I say It's OK(Nice).
