The profit rate assumes 350 kills per hour. Your actual profits may be higher or lower depending on your speed and luck.
Unicows may be killed for their 100% drop rate of unicorn horns, which are commonly used for both Herblore and Summoning. These creatures may be created in the Tower of Life by placing a unicorn horn and cowhide on the north-western altar. Unicows have a combat level of level 82 and attack using magic. Lower levelled players may wish to equip ranged armour, but food should not be necessary.
With an Ardougne cloak, the unicows have a chance of dropping noted unicorn horns instead, saving inventory space. Due to an update, this noted effect is permanently enabled and there is no way to disable it in order to guaranteed un-noted drops. However noted unicorn horn can be un-noted one at a time by either a right-click option on the Altar, or 'use' the horn on the Altar. With one unicorn horn and a war tortoise and inventory full of cowhides, it is possible to create and kill up to 45 unicows per trip. This will usually generate about 90 unicorn horns. Banking may be done via the fairy ring (code djp). Returning to the Tower of Life may be done via the fairy ring once more or using the Ardougne cloak teleport to the Kandarin Monastery. Six or more trips per hour are feasible.
With a Pack yak a small improvement in efficiency and a decrease in input cost can be gained.
