There's no easy or fast way to make credits.
Or generally good way to earn neither. It's about what you're good at, if you have artistic skills, then obviously textures, gfx etc. etc.
If you have good marketing skill then it's items etc.
on forums its art you need longer to make a set but if its really good you can make 200-300k
in game it think its betting if you have enought tc and much time you can make big profit on a big server

If you are a skilled payer i would recomend dueling in-game.
On forum selling some epic items like void or elf gives a lot tc, but first you need to have them
Dueling if your persistent then you can make 30k-100k in a day with a good start (10k) only duel if you skill cause its the fastest way to make tc and the fastest way to lose it
