Clash of Clans Goblin Helper Gem Value Guide

Hiring the Goblin Builder and Goblin Researcher is the most cost-effective way to convert Gems into raw progression time in Clash of Clans. Available during recurring events for players at Town Hall 7 and above, both helpers work at a flat rate of 40 Gems per 24 hours of upgrade time. This rate provides better time-reduction efficiency than buying Magic Books from the Trader or finishing upgrades instantly.

Unlock Requirements and How to Hire Them

Goblin helpers appear only while their recurring event is active, and they function as secondary labor slots in your Home Village under specific conditions:

1. Town Hall Level: Your village must be Town Hall 7 or higher.
2. Full Capacity: To hire the Goblin Builder, all standard Builders must already be busy. To hire the Goblin Researcher, your Laboratory must already be running an ongoing upgrade.
3. Resource Payment: Goblin helpers do not discount or replace regular build costs. You must pay the full Gold, Elixir, or Dark Elixir requirement in addition to the upfront Gem fee.

Once these conditions are met, selecting an un-upgraded building, hero, trap, troop, spell, or siege machine prompts the option to assign the respective Goblin helper.

Gem Efficiency: Goblin Helpers vs. Magic Books

Goblin helpers charge 40 Gems for every 24 hours of work, scaling linearly with the duration of the assigned project. Because Trader books carry fixed Gem prices, shorter upgrade timers favor Goblin labor.

For a 925-Gem Trader book to match the 40 Gems-per-day rate of a Goblin helper, an upgrade would need to take more than 23 days. Because Home Village upgrade timers currently cap below that duration, spending Gems directly on Goblin helpers yields more total build and research time per Gem than shop books.

Which Helper to Prioritize

If you have a limited stockpile of Gems (such as 500 to 1,500 Gems), spend them on the Goblin Researcher first.

Laboratory research takes significantly longer to complete across a full account than defensive structures, making the lab the primary progression bottleneck. Running the Goblin Researcher alongside your standard Laboratory effectively doubles your research output, allowing you to catch up on key offensive troops, spells, and siege machines without falling behind your Town Hall level.

When choosing specific projects:

• Goblin Researcher: Assign long, high-priority army components such as core war troops (Root Riders, Electro Dragons) or vital spells (Rage, Freeze) that take 10 to 14 days.
• Goblin Builder: If lab research is on schedule, use the Goblin Builder on resource storages during a new Town Hall transition so your primary Builders remain focused on offensive structures like Army Camps, Clan Castles, or Pet Houses. Alternatively, assign him to heavy core defenses with long timers, such as Scattershots, Eagle Artilleries, Monoliths, or Inferno Towers.

Rules and Cancellation Penalties

Before committing your Gems to an upgrade, account for two event mechanics:

• Late Starts Finish Safely: If a Goblin helper starts an upgrade before the event timer runs out, the worker stays on your base until that specific task finishes, even after the event officially ends. You can safely start a 12-to-14-day task in the final minutes of an event.
• No Gem Refunds on Cancellation: Canceling an ongoing upgrade assigned to a Goblin helper forfeits the spent Gold, Elixir, or Dark Elixir and does not refund the Gems used to hire the helper. Confirm your upgrade targets before paying the fee.
