The Oldak coil is an Invention device that is a part of the cave goblin technology tree, and requires level 70 Invention to unlock. Oldak coil costs 55 goblin currency, and is locked until the player unlocks the T1 upgrade Pestiferous components (requiring 40 Invention and 10 goblin currency), one of the T2 upgrades (requiring 50 Invention and 25 goblin currency per upgrade), and at least one T3 upgrade (requiring 60 Invention and 35 goblin currency per upgrade). It is the Magic variant of the dwarf multicannon. The Oldak coil takes up a 3x3 area of space when deployed, and it can attack targets within a 9x9 area. The experience gained from using the Oldak coil is dependent on the player's Magic XP selection in their Combat Settings.

Success in creating the blueprints earns 10,518 base Invention experience, or 52,591 experience at perfect optimisation.

The Oldak coil requires cannonballs as fuel, consuming one every time it attacks (even if it hits multiple targets), and it has a cannonball capacity of 30. When active, any enemy that is in range will be repeatedly attacked by bolts of lightning, and it can hit up to three enemies at once. It benefits from the same perks as the dwarf multicannon if unlocked, increasing the cannonball limit to 60 or 90 and allowing it to restock automatically if the player is in range.

If destroyed, it will need to be rebuilt. If lost, you will receive a message stating it was destroyed but that you can reclaim it from Nulodion, located near the entrance to the Dwarven Mine south of Ice Mountain. However, it can be used indefinitely if you keep picking it up and re-deploying it when you receive the decay warning.

It can be upgraded with an Oldak coil upgrade kit, which increases its damage by 50%, at a cost of 4,052,883 coins.

Update history

This information has been compiled as part of the update history project. Some updates may not be included – see here for how to help out!

• hotfix 20 February 2023 (Update):
  • Players are no longer able to place the cannons inside the Fort Forinthry.

• patch 20 September 2021 (Update):
  • All Multicannons now have a tooltip stating their maximum damage.

• hotfix 9 August 2021 (Update):
  • The extra damage from Dwarf Multicannon Upgrade Kits will now only be applied after the upgrade has been unlocked.

• patch 26 July 2021 (Update):
  • As you smash through the fearsome Nodon armies, you could be lucky enough to find special upgrade kits based on the Nodon's Siege Cannon technology. Each of these three kits can be used on your Dwarf Multicannon, Kinetic Cyclone or Oldak Coil to amp up their damage. The Dwarf multicannon also comes with an impressive new look!

• hotfix 25 May 2021:
  • Update of 24 May 2021 introduced a bug, where it was no longer possible to set-up and place Dwarven and Invention multicannons in several allowed instanced areas. This has been hotfixed.

• patch 29 July 2019 (Update):
  • The Oldak coil will no longer heal you if you have a Blood spell selected.

• patch 17 September 2018 (Update):
  • Due to a bug, Oldak coils and Kinetic cyclones can now be reclaimed from Nulodion near the entrance to the Dwarven Mine, if Nulodion cannot find your registered cannon/coil/cyclone on your current world.

• patch 29 January 2018 (Update):
  • Dwarven and Invention multi-cannons can now be reloaded and repaired (resetting their despawn time) by left-clicking them.

• hidden 4 December 2017 (Update):
  • A cannon decay status effect has been added, indicating the time remaining until the cannon stops firing.

• patch 4 December 2017 (Update):
  • A buff icon has been added to track the ammo stored in a cannon. This does not appear if the Restocking Cannon perk from Artisans' Workshop is active.

• patch 12 September 2016 (Update):
  • Adjusted the message for blocking cannons in the Slayer Tower since the Oldak coil is certainly not a dwarven invention.

• update 16 May 2016 (Update):
  • Added to game.

Trivia

• It is likely a reference to the Tesla coil which produces arcs of electricity.
• Originally, it required 1,725 inspiration to discover.
