Hammer Jam just launched in Clash of Clans, slashing upgrade times and costs by 50% across all Town Hall levels—except for supercharges and crafted defenses. This means you can push your base defenses or troop levels faster without draining your elixir and gold reserves as heavily.
Running from November 1 to November 17, 2025, the event also doubles resource collector production and capacity. If you're sitting on a maxed-out builder hall or eyeing that next big cannon upgrade, this is your window to stockpile and build without the usual grind holding you back. In my last push to Town Hall 14, boosts like this turned weeks of waiting into days of real progress.
Wastelands Theme Brings New Tactical Twists
The November season in Clash of Clans rolls out with a Wastelands vibe, including Meteor Obstacles that drop valuable ores when cleared. Starting November 8, 2025, a Meteor Observer building pops up outside your village, adding layers to resource gathering strategies.
Clan War Leagues heat up from November 1 to 17, 2025, while Goblin Builder and Researcher return until November 30, 2025, offering quick upgrades and research. Themed scenery and skins tie into the ruined kingdom aesthetic, but the real game-changer is how these discounts let you experiment with aggressive raiding builds or fortify defenses mid-season.
What Does Hammer Jam Mean for Your Clash of Clans Strategy?
With half-off upgrades, focus on high-impact investments like air defenses or hero levels that shift raid outcomes. Pair the 2x resource boost with efficient farming layouts to maximize gains—I've seen players climb leagues by timing builds around events like this.
When Do November Events End in Clash of Clans?
Hammer Jam wraps on November 17, 2025, but Clan Games start November 22, keeping the momentum. Goblin features and scenery last until November 30, 2025, so plan your attacks accordingly to leverage every boost.
These updates reward smart planning in Clash of Clans. If you're deep in clan wars, use the downtime reductions to adapt your army comps on the fly.
