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

Herb Storage
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.

About Herb Storage
Priority: Medium-LowHerb Storage holds your herb reserves. Since herbs are used in healing and are naturally slower to accumulate, maximising your storage cap ensures you never waste Herb Garden output.
Upgrade Tips
- 1Herbs are the hardest resource to gather on the world map — maximise storage so none goes to waste.
- 2Upgrade Herb Storage before major war events to bank enough herbs for mass healing.
- 3Keep Herb Storage level matched to your Herb Garden level.
