Short answer: Use this Last Asylum: Plague Walls calculator to total Wood, Grain, and Herb for any upgrade range before you spend speed-ups or alliance help.
Upgrade calculator
Walls
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 Walls 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 Walls
Priority: MediumWalls provide passive defence for your city, reducing the damage enemy attacks deal to your troops during sieges. Higher Wall levels increase your city's defence rating and can turn a losing defence into a draw or victory.
Upgrade Tips
- 1Walls are especially valuable if your Sanctuary is shielded — they provide the last line of active defence.
- 2Upgrade Walls when you're preparing for an Alliance war to protect your resource buildings.
- 3Walls don't need to match your Sanctuary level exactly, but keeping them within 5 levels is recommended.
