s there an english dubbed version of the anime?

Yes there is just تلاش claymore, کلیموری English Dub

if your still looking for it آپ can watch it on youtube, there's dubbed and subbed in English (in youtube)

There's almost always a dub of an anime... Dubbed isn't as good in most cases, though.

I Imagine searching for it through Google would be the best starting point.

یا آپ can just buy it on Amazon. Here: link
