Shipped one Fur, then search for Raven. Check her "Collection" to find Furs available for 30G. Purchase some of them and go to the crafting table to turn them into Yarn. You can ship them for 80G, which doubles your profit and earns you crafting experience.
Level status resistance without fighting
You can level up your status resistance without fighting by drinking Object X and then going to Jones or sleeping to cure them. Object X is easy to get by simply using objects that can't make a potion (such as scrap metal). Degenerative effects can't actually kill your character, so you can give yourself all the status effects without having to worry about dying in combat. After you cure yourself you simply drink another Object X.
Leveling Forging Skill
After unlocking and buying a forge, it is fairly easy to quickly level up the forging skill. Making anything with the forge will give experience, with higher difficulty items giving more experience. The only factor that determines the experienced gained for each item forged is the required level of the item- thus making items that require fewer and less rare materials is the best way to level. One of the easiest ways to take advantage of this is to mass-produce hoes, which are made from only one item, an ore. Make sure that you have obtained the recipe for the Cheap Hoe, and check to see that you have a decent supply of Iron. Mass-produce Cheap Hoes by using the arrow at the lower right corner of the touch screen, watching the required RP to insure that you will not faint. Make as many as you can hold. At lower levels, it is also a good idea to upgrade the hoes up to level ten using whatever useless items you have picked up to gain more experience. The experience needed to level the forging skill increases with each level, so after a while, forging Cheap Hoes will become less effective for raising your forging skill. At this point, start making the next level of hoe, and continue to mass-produce the appropriate leveled hoes with your extra materials to quickly level your forging skill.
Maximum Throwing and Walking Skills early in the game
If you'd like to use the fists or hand-to-hand combat, there's a trick in leveling up your throwing skills to max by repeatedly throwing an item. Do this after you completed Vishnal's tutorial on farming. Go to a corner and press the directional button where you keep walking but stays at the same place then repeatedly press A to throw the held item(this does not upgrade walking though).To level up walking, just walk around the farm. Also, do not remove the grass, till the soil, and water the tilled soil while Vishnal's farming tutorial is not yet complete, it does not give you experience. Note: This requires very long patience because this might take a while. Also, do not leave the farm in doing this trick, because time will start to flow again when you do so (time stops when Vishnal is still teaching you).
Refight bosses multiple times per day
If, after defeating a boss, you use your Teleport spell to exit the room before the door barriers vanish, the game will not actually consider the boss to be defeated, allowing you to return and refight that boss on the same day. This can be useful for grinding Prince/ss Points and farming drops from a particular boss. Simply wait for the boss's death animation to finish and the game to produce its drops and give you your PP, and then teleport out. The drops will still be in the room when you come back! Be aware that this glitch cannot be used in the Sharance Maze, due to the randomly generated nature of the place.
