Borrowed Power

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. It is unlocked by speaking to Pauline with 430,000 produce points. With this spell, the player has the ability to cast one of a selection of spells from the standard spellbook.

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

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

In order to use Borrowed Power, the player must first claim the 'Set Borrowed Power!' wish by claiming-reward to Pauline, which costs 18,000 produce points. This requires enough runes to cast the spell 1,000 times, resulting in 1,000 charges of that spell. The runes are consumed after setting a spell to Borrowed Power. Casting Borrowed Power then requires 3 astral runes, removing one charge.

Usage[edit | edit source]

Most of the spells that Borrowed Power can be set to are of relatively limited usefulness, with the exception of Vulnerability. If the player is on the ancient spellbook, they can cast Spellbook Swap to switch the lunar spellbook. From there, Vulnerability can be cast if it has been set to Borrowed Power. Casting Vulnerability this way can potentially save the player one inventory spot; Spellbook Swapping to the standard spellbook will not be necessary, so a large rune pouch that would normally hold chaos and soul runes for Vulnerability will not need to be brought.

Once the player has Spellbook Swapped to the lunar spellbook, Vulnerability must be cast with an action bar keybind; Borrowed Power cannot be directly cast while the player is under the effects of Spellbook Swap.

Melee and ranged users on the lunar spellbook can access Vulnerability from Borrowed Power in addition to other useful combat spells such as Vengeance and Disruption Shield at the cost of some inventory spaces for the magic weapon switches and the runes. With the release of the Ingenuity of the Humans ability, a magic weapon is no longer necessary as the ability will guarantee Vulnerability will successfully hit if it is the first attack used after activation.
