Mandatory Things Needed For a Faction Server?

[TheGreatScrubini]

I want to make a faction server but I'm not sure what are all the mandatory things needed in order to make a faction server because I haven't been catching up with all the updates?

What are the mandatory types of things like plugins, pvp system, server version, etc?

Help please

I don't really play factions but I have played Vanity and I liked it so I would go on there and check out what they have
