Around halfway to level sixty though quests begin
When you first start out Cabal Alz the majority of your exp will come from quests. So try to fill your log with as many quests as you can.
But don’t always take the ones that require you to visit a dungeon or kill elite. These take organization so you won’t get to them right away and they’ll just sit in your quest log taking up space for other quests.
Around halfway to level sixty though quests begin to slack off in terms of experience and you will be forced to do a lot of grinding.
When grinding, or killing mobs repeatedly for exp, always pick your targets carefully, one of the best things to do is try to pick mobs that give some type of reputation gains when killed.
You generally don’t see these until higher levels, but that’s when you’ll be doing most of your grinding anyway. Another good idea is to grind on mobs that bring in the most cash. Humanoids drop money and cloth and have a slightly higher chance of dropping green armor and weapons.
Beasts will only drop animal parts that don’t sell for much. But if you are a skinner you can make money that way.
You must also use the Rest System to your advantage. It can double the amount of EXP you get so always try to log out at an inn.
