Alchemist's amulet (charged)

The alchemist's amulet is an item obtained by using one or more Alchemist's amulet fragments, which were available on the Squeal of Fortune for the weekend of 7 September, to construct it.

When constructed, the player is granted a number of coins based on the number of fragments used in tandem to construct it, as well as the players total level. Players only win one fragment at a time and may create their amulet with any number of fragments; however, each additional fragment used doubles the amount of coins granted, starting with 10,000 coins and increasing to a maximum of 5,120,000 coins. The formula 5,000 ×2 (f) where f is the number of fragments used for the amulet, can be used to calculate the amount of coins received.

When using 10 fragments, the player will produce an alchemist's amulet (charged) which may be used to cast the High Level Alchemy spell on any spellbook without using any runes up to 10 times per day, so long as the player has at least 55 Magic. Note that these free casts are counted for each player and not each amulet; i.e. having 2 charged amulets will not allow the player 20 free casts of high alchemy per day. Using any number less than the full ten fragments will produce an alchemist's amulet (uncharged) which may not be charged with any further fragments; however, players may gain more than 10 fragments and create more than one amulet.
