If you're a skilled artist you could also make textures
and any other art or texture related stuff,
The art section is pretty dead at the moment so it
would be a good opportunity for you
Then there's duels, it's risky but if you're good at the
game and feel confident you could earn a bunch of tc
or items, though you have to start with something, right?
That's where the bet servers come. You can host a bet server
and earn rake/house by simply hosting or looking over a server (co-hosting),
you get 9% of tc from every round from the lost player's bets if you set a command /house.
Hope this helps
