Short answer: Use this Last Asylum: Plague Barracks calculator to total Wood, Grain, and Herb for any upgrade range before you spend speed-ups or alliance help.
Upgrade calculator
Barracks
Each row is one upgrade: level N → N+1. Totals sum wood, grain, herbs, and base build time for steps we have in the guide. Level pickers run through 30; if your target is above the last level with data (currently 30), totals only cover upgrades through that level.
*data can be incorrect too, please verify it before using

I made a Barracks upgrade calculator for Last Asylum: Plague players who want to see the total Wood, Grain, and Herb cost before committing. It covers level-to-level planning and is free to use.

About Barracks
Priority: HighThe Barracks is your primary military training facility, directly controlling how fast you can train troops and how large your army can grow. A higher-level Barracks increases troop training speed and unlocks higher-tier soldiers, giving you a critical edge in Alliance battles and PvP.
Upgrade Tips
- 1Upgrade Barracks alongside your Infirmary — a larger army means more potential casualties that need healing.
- 2Higher Barracks levels unlock Tier 3 and T4 troops which have dramatically better combat stats.
- 3During Alliance events, max troop training speed from Barracks upgrades can win or lose rallies.
