Thanks guys!
These otherworld gnolls are almost more like display models with the level of detail, and the price tag. It is tough to get an army of them, or a big encounter. I wonder if the old partha ones in the box set are still available from Iron Wind Metals.
* just checked and "Harag Skullsmasher and his Gnoll Raiders" was the partha boxed set and is not easy to find.
