Reason: Needs to recalculate new drops due to 12 March update and verify default KPH due to lifepoints change

The profit rate assumes 250 kills per hour. Your actual profit may be higher or lower depending on your speed.

Cave horrors drop the black mask, worth 519,132, at a believed 1/512 rate. They are located in the Mos Le'Harmless Caves, which require Cabin Fever to be completed. You'll also need a light source and a witchwood icon to avoid taking a great deal of damage. The easiest way to get to the caves would be either taking the fairy ring DIP (requires A Fairy Tale III - Battle at Ork's Rift), or taking Bill Teach's boat to Mos Le'Harmless and travelling east from the town.

The cave horrors are a bit spread out, and they have 5,000 life points. With decent armour they don't do enough damage to be very troublesome, but a bunyip or healing abilities can be used if needed. With mid- to high-level equipment, it's very possible to kill 250 cave horrors per hour. They have very few drops besides the black mask worth picking up.
