HelpPlease explain consoles

At the moment I am using vindictus+ and it is working okay for the most part.

But in all the posts i keep hearing about different consoles. Can someone please recommend an easy-to-use console and explain how to set it up and use it?

I don't know what to comment on this "easy-to-use console" part.
Find HD's public console on the Hacks section, discover working commands, input??

Or you can just live on with copy pasting leeched hfs files.

Modified hfs files and console commands/bindings can work together. Followup on the binding guide.

I never touched rev gravity. It should turn off IIRC, but unless you are doing related stuff with it, it's pretty much a "fun" hack IMO.

Some console commands will reset after passing through a stage in dungeon runs, hence you need to input the command again, like 999 secondary weapons command. Where else some will remain throughout until you close the client, like mob delay commands.

Unbind it, change the command's value to 3 and bind it?

Commands usually comes with a value with it. Mob delay 99999, all those do a lil thinking and find out yourself.
