Short answer: Use this Last Asylum: Plague Infirmary calculator to total Wood, Grain, and Herb for any upgrade range before you spend speed-ups or alliance help.

Infirmary
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.

I made a Infirmary 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 Infirmary
Priority: HighThe Infirmary heals wounded troops after combat, converting them from 'severely wounded' back into active forces. A high-level Infirmary directly determines how many troops you can recover after a battle, making it one of the most strategically important buildings for active fighters.
Upgrade Tips
- 1Never let your Infirmary lag behind your Barracks — losing troops permanently because your Infirmary was full is a costly mistake.
- 2Higher Infirmary levels increase both bed capacity and healing speed.
- 3Use herbs to speed up healing during active war events rather than waiting for natural recovery.
