Keep 35 Rush: Resource & Time Budget
What it actually costs to push a Keep from the low 30s to 35 – the resource bill, the time bill, and the prerequisites people forget.
A Keep rush looks simple on paper: pick a level, farm the resources, hit upgrade. In practice the Keep is the most prerequisite-heavy building in the game, and the buildings it depends on are themselves gated by other buildings. The bill is rarely just the Keep.
The three costs of any Keep push
Every upgrade range has three separate budgets, and you should plan all three before you spend anything:
- Resources – food, wood, stone and ore summed across every level in the range, not just the final level.
- Time – the raw construction seconds before speedups, boosts, or double-time events.
- Prerequisites – the other buildings that must reach a given level first, resolved recursively down the whole tree.
Plan it in one pass
Rather than checking each building by hand, drop your current and desired Keep level into the calculator. It returns the exact resource totals, the raw build time, and the complete prerequisite chain – every building and the level it must reach – so nothing surprises you mid-rush.

A sane order of operations
- Clear the prerequisites first – a Keep upgrade that is blocked wastes your speedups sitting idle.
- Stockpile to the full range, not one level at a time, so you are not caught short at the most expensive final step.
- Save the double-time and construction-boost events for the single largest upgrade in the range.
Do the math once, up front, and a Keep rush becomes a scheduling problem instead of a series of nasty surprises.
