|Examine||It's sporting the height of wool-based fashion.|
They are significantly more uncommon than white sheep, and may only be found in Fred the Farmer's farm in Lumbridge, and just south-west of the Dark Wizards' Tower near Falador. Since Fred's farm only has two black sheep (and an unshearable black lamb), the Dark Wizards Tower sheep are a superior source of obtain black wool.
Black sheep were introduced with the 15 December 2009 rework to the Sheep Shearer quest. In the original version of the quest, Fred the Farmer requested 20 balls of wool, which players were able to simply buy from other players without shearing any sheep. The rework of the quest introduced the untradeable balls of black wool and their associated sheep to combat this, ensuring that players had to actually shear sheep to complete the quest.
The 9 October 2017 Free-to-play update made their wool obtainable outside of the quest, and added some to the Dark Wizard's Tower. It also gave their wool an additional use, being an ingredient in crafting black wizard robes.
