What is the funcion of amulet? (runescape)

整o左 amulet 之後一定要加ball of wool 先可以戴的。
BALL OF WOOL 整法：
~ 帶shear
~ 去有sheep (羊)的地方
~ use shear with sheep (NOT ram)
~ 去有spinning wheels的地方 (如Lumbridge 二樓、Barbarian Village、Falador 南門一入去轉西行), use wool with spinning wheels → balls of wool
普通amulet：
~ use amulet(u) [即係未穿string的amulet] with ball of wool → amulet (可戴啦)
經魔法enchant 的amulets：
~ 所有需要enchant的amulets 都要係stringed amulets。
