Arcane capacitor (c) detail

The arcane capacitor (c) is a charged version of the Arcane capacitor amulet (u), obtained from Livid Farm for 18,000 produce points. This item is required for the use of the level 99 Lunar spell Borrowed Power. The player may only possess one at a time, and it degrades to dust after 1,000 uses.

The amulet may be charged with the runes for 1,000 casts of a spell from the list below (elemental staves may not be used). Once charged, the only way to remove the charges is either by using them or selecting the "Remove-charge" option. The amulet is then destroyed, although any unused runes are refunded.

Assuming the maximum activities per cycle at Livid Farm, and the use of a mud staff, the cost of runes at Grand Exchange price for the needed 18,000 points is 607,933.

Other alternatives to Borrowed Power already exist such as Spellbook Swap which has a slightly lower Magic requirement of 96 and does not require any Produce Points in order to be used, and is not restricted to a selected amount of spells like Borrowed Power.

On 23 October 2017 all instances of arcane capacitor (c) were converted into disused arcane capacitor (c), with all the charges moved to the Borrowed Power spell itself.


The arcane capacitor can be charged with 1,000 charges of the following spells:
