Skeletal horror

The Skeletal Horror is a monster you can kill once the wishlist for the quest Fur 'n' Seek is complete, once a week. While fighting it, both hands and the tail will come off. Pick them up and bury these to make its level go down. After the parts are buried you can kill it and talk to the Odd Old Man for your reward.

Habitat(s)
East of the Odd Old Man once the wish list for the second part of Fur 'n' Seek is complete

Strategy
The Skeletal Horror can be very dangerous for anyone not prepared. Wear high melee defense armor such as Barrows or Dragon and pray magic as the magic attack appears to be faster than his melee and much more accurate. The Skeletal Horror will not attack you with the attack-type that you are praying from. High healing food such as sharks or monkfish is recommended.

Use a basic weapon set up of a Dragon Dagger (p++) and an Abyssal Whip or other strong melee weapon as well as a super set of potions. Use all four Dragon Dagger specials and then switch to your other weapon to finish him off.

At times of the fight pieces of the Skeletal Horror's limbs and tail will fall off and be thrown to the other side of the battlefield. Take the time to pick up these pieces and bury them as letting them return to its master will heal him greatly. When you bury the pieces the Skeletal Horror will be weakened, dropping its max hit, accuracy, and combat level.
