Huge armoured and scarred gnoll warriors that lead their kin into battle.
Gnolls are not particularly brave, and rely on sheer numbers to overwhelm their enemies. Gnoll Gnawers get confident when lots of allies are around, giving them a boost to their damage. If those allies die or don't stay close to him, his courage (and damage bonus) disappear at once.
Gnoll Gnawers are essentially the players' introduction to physical armour. As such, they aren't very difficult to dealt with unless you have been neglecting magic towers. Certain Gnoll Gnawers are carried into battle by Perythons, allowing them to temporarily bypass soldiers and druids until the Perythons are forced to drop them.
