Clash of Clans: TH17 star upgrades will no longer gate TH18 after the November update
Supercell says players aiming for Town Hall 18 can reconsider those upgrades during Hammer Jam; the change takes effect after the November update.
Players planning the move from Town Hall 17 to Town Hall 18 have a new reason to revisit their builder queue. On November 5, the official Clash of Clans account said star upgrade levels will no longer be required for that transition after the November update.
The change is still ahead: Supercell specified “after the November update” without giving an exact deployment time. Until then, the new requirement should not be treated as live. The announcement did not say whether other upgrade requirements will change.
For chiefs whose goal is TH18, the official account suggests considering a pause on these star upgrades and directing Hammer Jam resources elsewhere. The official season calendar lists Hammer Jam for November 1–15, with half-price upgrade costs and timers plus doubled resource collector production and capacity. The best alternative depends on each village’s progress.
For context, Supercell’s original TH17 notes describe the Inferno Artillery as the Town Hall weapon created by merging the Town Hall and Eagle Artillery. It remains a TH17 defense. The new announcement addresses the requirement to reach TH18; it does not promise refunds for completed upgrades or explain what happens to one already underway.
