Instructions
Hunting Unicorns
Travel to one of the locations where you can find Unicorns: Lumbridge Swamp; north of the barbarian village; Northern Entrana, near the Law Altar; the southeast cage of Ardougne Zoo; southeast of Camelot Castle; southeast of Rellekka; southeast of Varrock; and south of Seers Village.
Fight and kill any Unicorns you find. Unicorns with less the 100 life points left will attempt to flee.
Add the horn that the dead Unicorn drops to your inventory by left-clicking on it. Unicorns drop bones which you can also pick up.
Hunting Black Unicorns
Travel to the areas where Black Unicorns appear: in the Wilderness north of Edgeville at levels 12 to 16; and east of Rellekka.
Hunt and kill any Black Unicorns you can find. Black Unicorns are stronger and more aggressive than Unicorns. Baby Black Unicorns do not drop horns.
Pick up the horns dropped by the dead Black Unicorns by left-clicking on them; Black Unicorns also drop bones and may also drop other items, such as Charms.
Unicows
Collect a number of cow hides by purchasing them or killing cows and taking the hides they drop. Collect at least one Unicorn horn.
Travel to the Tower of Life. Enter the basement via the trap door on the ground floor and go to the Creature Creator.
Place a cow hide and a Unicorn horn on the Unicow altar. Activate the altar to produce a Unicow.
Fight and kill the Unicow; pick up the two, three or four horns it drops. Keep creating Unicows and killing them until you have enough horns.
