dropped by ankous in the security of stronghold
The Left Skull Half is dropped by Ankous on the fourth level of the Stronghold of Security.
Use them on eachother, as part of a sceptre.
There is no way of telling, all monsters drop at random, if there were certain kills you have to get, the game would hardly be any fun.
On the left hand side of the castle
no
A skull on his left side of his "v" area. :) and a 7 on his left wrist.
The Bottom of Sceptre in runescape is combined with the Top of Sceptre to make a Runed Sceptre. This Runed Sceptre is then combined with the Strange Skull (made from a Right Skull Half and a Left Skull Half) to make a Skull Sceptre. This skull sceptre then allows the user to teleport to Barbarian Village (the location of the Stronghold of Security) 10 times (20 times if made while wearing Varrock Armour).
the goblins on the first floor drop it.
you can teleport to barbarian villiage.
because i dont know
Draynor Village, Wizard's Tower.
Will not only cause pressure and damage to that side of the brain, the left side of the brain will also be pushed up against the hard surface of the skull, causing damage to the left side of the brain as well.
