How to get Commands and Claims on modded minecraft
Commands and Homes
Mods are marked server-side or both, depending on where they need to be installed. Server-side needs to be on the server
Other Required mods (Some may already exist in your pack)
FTB Essentials adds Commands such as
home
sethome
tpa
rtp
back
The commands & Number of homes can be configured in the world serverconfig server.
Claims
FTB Claims (BOTH)
FTB Claims is another FTB Mod that adds basic claims. I only recommend using it if Open Parties & claims is not available for your version, as it provides less protection.
Open parties and claims (SERVER)
This is the mod I recommend for claiming. If running Xaero's World Map. It will add the ability to claim via a menu. Having the mod on the client also adds a lot of flexibility. It can be run by itself using commands in chat. These are listed on the mods CurseForge page
