The bone spear on RuneScape can be obtained by purchasing it from the Grand Exchange in Varrock or from the Bone Weapons store run by Nardok after you're done with "The Lost Tribe" quest. The bone spear is a very weak weapon, and is not a very common weapon seen used by players in RuneScape. The more common Bronze to Rune weapons work better than bone weapons. Bone spears can also be obtained from monster drops by killing Cave Goblins and Cave Goblin Guards which are very easy to kill, as they are level 3 and level 24/26.
There isn't a Saradomin Spear? There is a Zamorakian Spear but there is no weapon similar to it in looks.
I personally prefer the whip since it is more for the offensive and the spear is more for the defensive. The whip has +82 in strength and slash stat which makes it one of the best 1-wielded weapons in runescape.
Bone weapons can be easily bought from the Grand Exchange at a reasonable price.

You use a normal spear (steel or better), and poison it. For this quest, you specifically have to poison it with karambwan paste, which you make during the quest (from a poison karambwan).
