Holy symbols are amulets that resemble the Runescape god Saradomin. In F2P, they are seconded only by the twisted bird skull necklace. The holy symbol gives a +8 prayer bonus, while the twisted bird skull necklace gives a +9 bonus.
A player may craft an unstrung symbol, using a silver bar on a furnace. This requires level 16 crafting, and gives the player 50 crafting experience. A player may then string the unstrung symbol, using a ball of wool, to make an unholy symbol, giving the player 4 crafting experience. The unholy symbol may then taken to Brother Jered, in the monastery, to complete the holy symbol.
