Prerequisite building gap and resource chest calculator
The two biggest obstacles in HQ upgrades are lagging prerequisite buildings and the iron, food, or gold shortage that occurs at the time of upgrading. Use the tool below to first check which buildings need to be upgraded and by how many levels for your target HQ level; then calculate whether the resource packs in your inventory cover the target cost.
1) HQ prerequisite building check
Enter your target HQ level and the current level of the second required building shown in the game.
2) Bag resources vs. upgrade cost (millions / thousands)
Enter the amount required on the upgrade screen and your unprotected + bag resources in millions (M) (e.g. 79.3 for 79.3M, 0.5 for 500K) or as chest counts.
Tip: for time calculations use the Last War speedup calculator.
Automatically manage the HQ requirement chain and resources
During HQ upgrades, tracking which building is missing at each level, starting the next building as soon as construction finishes, and replenishing missing resources one by one from your bag takes time. Last War Bot (g29) automates this process on the official Windows PC client by reading the screen:
- HQ requirement chain: Reads the prerequisite buildings required by the HQ and assigns the idle builder to that building first.
- Research building requirement priority: If research is blocked by a building requirement, it directs the builder to the relevant building first.
- Resource replenishment from bag: When the “Insufficient Resources” window pops up while upgrading buildings, it uses the 50K iron/food and choice chests from your bag; it never clicks the diamond “Complete All” or “Buy” buttons.
- Smart resource gathering: Reads the resources on the top bar and dispatches idle squads to the resource you have the least of (food, iron, gold).
