Why zone timing matters
A new zone can increase opportunity and pressure at the same time. Buying too early makes it harder to tell whether your units, upgrades, or layout caused the next failure.
- Do not expand during repeated leaks.
- Keep a repair buffer.
- Use offline income before the purchase if it closes the gap.
A simple timing test
Run one normal defense before buying. If the current area clears cleanly, the new zone is safer. If it barely survives, upgrade first.
- Clean clear means safer expansion.
- Barely surviving means wait.
- Failed run means fix defense.
After buying
Do one short review run immediately after the new zone opens. This tells you whether the next spend should be coverage, damage, or income.
- Watch the first new pressure point.
- Avoid rerolling blindly.
- Update the planner inputs.
