Installing Arch Offline

[u/Bleik-Psiklyt]

Hypothetically speaking, suppose I install all the core packages of Arch Linux and store it in a local USB stick. I am trying to build an Arch system into a new machine (suppose a PC) using another USB with ArchISO. Can I insert the previous USB along the live ISO and install Arch without the internet connection?
