Borrowed Power is a spell in the Lunar spellbook. Level 99 Magic as well as work at Livid Farm are required for using this spell, as it is unlocked by speaking to Pauline for 430,000 produce points. With this spell, you have the ability to cast one of a selection of spells from the standard spellbook, while wearing an arcane capacitor necklace charged with the runes for that spell.

It allows you to cast one of the following standard spells at a time:

Air Wave icon Wind Wave Slayer Dart icon Slayer Dart Teleport to House icon Teleport to House
Water Wave icon Water Wave Vulnerability icon Vulnerability Telekinetic Grab icon Telekinetic Grab
Earth Wave icon Earth Wave Enfeeble icon Enfeeble High Level Alchemy icon High Level Alchemy
Fire Wave icon Fire Wave Entangle icon Entangle Bones to Peaches icon Bones to Peaches

In order to use the Borrowed Power spell, you must first charge your arcane capacitor necklace. You will need 1,000 times the normal runes required for that spell, resulting in 1,000 charges of that spell on your arcane capacitor necklace. It is important to be sure of what spell one wants to charge the necklace with, as only one spell's runes may be used to charge the necklace. Only one of Borrowed Power's spells can be accessed, as only one necklace can be owned at a given time. Casting the spell then requires 3 astral runes and 1 charge from your arcane capacitor necklace. Autocast can be set via the ability bar. The necklace needs to be worn to be effective. Upon using up your last charge on your necklace, you get a message saying "Your amulet of power has run out of charge and has crumbled to dust. You will need to get another one from Pauline to continue using Borrowed Power" and you will lose your capacitor.

This spell is rather unpopular as many believe the spell selection is underpowered or useless. It takes quite some time to achieve the spell, costs three extra astral runes and the necklace must be worn while casting Borrowed Power, making it impossible to wear other necklaces which give magic damage boosts such as the arcane stream necklace. Furthermore, it cannot be taken into certain minigames such as those which do not allow items to be brought.

  • This is currently the only spell that needs 99 Magic.
  • Attempting to cast High Alchemy with the explorer's ring 4, wearing the arcane capacitor set to High Alchemy, will cause a "You don't have enough astral runes" message to appear. It does nothing and no charges from the capacitor or astral runes will be lost when High Alchemy is cast from the ring.
  • It was once possible to be able to cast High Alchemy on three astral runes to consume one astral rune and no charges. This was patched on 22 May.
  • It was released on 23 August 2011, along with many other new minigame rewards
