There is a couple of missions that can get you easy money.

-Willow Creek:
The mission mystery willow.it give 100 g and exp but it requires 5 peices of info
that you can only gain by doing quests.Overall you get about 500 g and exp. The mission
temptuous times.This mission gives you 200 g and 200 exp just for beating a werewolf. 
Also you get a pet design that sells for 125 g.NOTE-you can only have one pet design or
pet of dark wolf in your bag so you would have to sell one to get another one.

-Marshes:
The mission camping out.you get 100 g and 100 exp for getting 8 peices of lumber off 
swamp trees with 1 hp and dont attack easy.NOTE-occasionly a good glitch happens when 
battling these trees.if the server has 1000 or more people on it then when battling a 
tree you hp goes to 0 and you dont die.so you could any battle. If you have more ways
of getting money and exp pm me them and i will ad them and credit you.
