what is the difference between a lvl 5, lvl 20 and lvl 40 character? I can see how working with thier specials improves their performance but not how thier levels affects anything. likewise was does upgrading a room do if it is not a production or learning area? I upgrade a medbay and it produces faster, but what happens when I upgrade a living quarters? thanks, T

The higher level your dweller is the more health they have.

If you upgrade a living quarter it raises the dweller capacity of your vault. Meaning you can have more dwellers.

In my experience, the higher the level is, the longer he or she can survive outside the vault.

I once tested this with 2 same level Endurance but different regular levels. Turned out that the higher level one survived much longer.

ok makes sense, I will test it out. thanks! T
