String Jewellery is a level 80 Magic spell which strings amulets without the need for a ball of wool. The spell takes 1.8 seconds per amulet strung, and gives 4 Crafting experience and 83 Magic experience per amulet. Once clicked, it will string each amulet one by one in your inventory, giving you experience per strung amulet. This is known to be a very fast, and a reduced clicking alternative of training Magic, as a single click gives experience for the entire inventory, unlike High Alchemy or Plank Make, where experience is earned per click. While only half paying attention, this spell can provide over 130k experience per hour or around 1,500 casts*, reaching around 160k experience per hour or around 1900-2000 casts* when full attention is given.

* Figures were derived with this equation: (Magic xp/hour / Magic xp per cast)

130,000 / 83 = 1,566.26 (or 1,500-1,600) = casts per hour
160,000 / 83 = 1,927.71 (or 1,900-2,000) = casts per hour

Ideally, if one's inventory only consists of the astral runes and the jewellery about to be strung, the initial amount of experience per inventory would be 2,241 Magic XP, and 108 Crafting XP.

The spell can also be used to string Salve amulets, unstrung symbols and unstrung emblems.

As with all Lunar spells, the quest Lunar Diplomacy must be completed to cast this spell.

Note that though you only need to click to cast this spell once per inventory, the rune cost is one cast for each amulet in your inventory, NOT the rune cost of one cast for all amulets. (e.g. when wielding mud battlestaff and inventory consists of astral runes and 27 unstrung amulets, with one cast you will string 27 amulets at a cost of 54 astral Runes.)

When casting, the spell is interrupted by walking around or interactions with other players or NPCs.

Remember, you cannot use Ancient Magicks or regular magic if you are using Lunar spells, except by use of the Spellbook Swap spell which is only available on Lunar spellbook.
