Gold Pass & build boost
Match in-game −15% builder speed in the planner toolbar.
Gold Pass reduces home village build time by about 15%. Season challenges can push effective boost slightly higher - ClashCookie offers Gold Pass and Max boost presets on the planner toolbar.
What it affects
Builder timeline, forward finish dates, and gem-to-rush estimates all scale with your selected boost mode.
Lab and hero timers are not builder boosts - only home village building upgrades on the builder timeline.
When to use Max
Max (~17%) approximates Gold Pass plus active season builder perks. Pick the mode that matches how you play so your plan matches reality.
