Fengundar blue (to level 50) mobs in Iarnwood forest have 70% Melee resists

The blue (to level 50) Fengundar mobs in Iarnwood forest have 70% melee resists. Hitting them with arrows and spear, they take less than half damage.
Also, they appear to count as humanoid creatures towards tasks, but they are not humanoid (they're reptile according to bestiaries online)
