Clash of Clans November Prep Guide: Hammer Jam and Town Hall Update

To get the most value out of the November season in Clash of Clans, balance early Hammer Jam construction discounts with Clan War Leagues (CWL) commitments, use mid-month resource boosts to upgrade walls, and hoard high-tier Magic Items for the upcoming Town Hall update.

November Event Schedule and Priorities

The November calendar focuses heavily on village progression, starting with discount events and ending with preparations for the next Town Hall release.

Balancing Week 1: CWL and Hammer Jam

The season opens on November 1st with Hammer Jam running alongside Clan War Leagues. CWL requires your active Hero roster to secure stars and League Medals, while Hammer Jam slashes construction costs. Upgrading Heroes during this week disables them for CWL attacks unless you use instant-finish items.

To maximize builder uptime without hurting your clan's war performance:

• Upgrade Core Defenses: Assign builders to non-Hero defensive buildings such as X-Bows, Inferno Towers, and Scattershots to take advantage of reduced gold costs while keeping your offensive lineup active.
• Avoid Offensive Bottlenecks: Do not start an upgrade on the Spell Factory, Clan Castle, or Hero Hall during CWL unless you immediately complete it with a Book of Building.
• Manage Roster Swaps: If your clan rotates players during CWL, use your bench days to upgrade a Hero, compressing the upgrade time with a Builder Potion before you rotate back into the war lineup.

Mid-Month Farming and 4x Star Bonuses

After CWL ends, focus shifts to high-volume resource farming to capitalize on Hammer Jam discounts and the 4x Star Bonus.

The eight-attack daily cap in Legend League limits the total loot you can harvest during limited-time discount windows. Dropping trophies into Titan I, Champion II, or Master League removes this attack restriction and lets you run continuous raids.

An army of Sneaky Goblins supported by Jump Spells and Invisibility Spells offers efficient resource collection:

1. Target Perimeter Mines and Collectors: Look for inactive bases with full resource collectors positioned outside the walls.
2. Snipe Town Halls: Direct Sneaky Goblins into the Town Hall compartment under Invisibility Spells to secure the Star Bonus and maintain your trophy range.
3. Leave One Builder Free for Walls: Keep a single builder available during active farming sessions. Dump excess Gold and Elixir into discounted wall segments, then assign that builder to an overnight defense upgrade before logging off.

Storing Magic Items for the Town Hall Update

Week four features Clan Games, offering a final opportunity to stock up on Magic Items before the major Town Hall update arrives. Rather than spending these rewards on existing lower-tier defenses, hold key items in your inventory:

• Book of Building: Save this to instantly finish the new Town Hall or the Laboratory once the update goes live.
• Hammer of Building: Use this on the new Town Hall or a high-cost core building to bypass resource requirements and build times entirely.
• Rune of Gold and Rune of Dark Elixir: Hold these to instantly refill storages for new defensive levels or initial Hero upgrades.
• Book of Heroes: Save this to finish early levels on new Hero tiers without benching them from regular attacks.

Final Preparations Before the Update Maintenance

In the final 48 to 72 hours before the scheduled update, stop assigning builders to projects with long timers. Starting a multi-day upgrade right before maintenance locks that builder out of constructing newly introduced defenses, buildings, or traps on launch day.

Stagger existing upgrades so at least one or two builders finish within 2 to 6 hours of the maintenance break. Fill all standard resource storages to capacity and leave your Clan Castle Treasury untouched after Clan Games concludes. Having free builders and capped resources allows you to start priority Laboratory research and place new structures immediately when servers reopen.
