Last Z HQ Upgrade Guide and HQ35 Planner
The HQ planner turns a long upgrade path into checkpoints, resource totals, prerequisite buildings, hero-cap milestones, and an adjusted time estimate.
Adjust for bonuses
Sophia resource discounts and construction-speed bonuses can change the planning estimate. Enter the bonus shown on your account and confirm the final cost in game before starting.
Treat requirements as a checklist
Required-building and timer information can change after patches or differ by server stage. The planner is designed to prevent surprises, not replace the live upgrade screen.
