Starting in a new server.

Looting while training no longer impedes progress!

When you first start in a new world I highly recommend you do not sell anything unless it's a double of something (good stuff preferred), an item you can not use, or scrolls that aren't made for your character or have less value or are too dangerous to use. I'd also recommend creating a secondary character(s) as a mule(s) (level 10 warrior 1st job will be good for this), to store things like scrolls and stuff you may want for later.

Also, stick to using Maker as much as possible for your equips, using item forgers, and other equips until you have enough for better stuff.

I recommend at least getting a 90 day Shop Permit, a Pet, and a Auto HP or MP pouch depending on the type of character you are using. Let the pet heal for you. This will save a lot of wasted potions and money over time. A Meso Magnet never hurts either. Seriously, be a penny pincher and loot all the time even if it's small amounts. If you have excess plates, gemstones, and crystals you aren't using or don't need, sell them. If you have extra gear, sell it (NPC off anything with below average stats with the name of the item in a grey color, but sell off White and Blue labeled gear for profits, unless it has potential then sell it anyway). BTW, if you have any money left over from those, buy Gachapon tickets and use them in Mushroom Shrine for stuff to sell, or even keep.

You'll want to go slow at first. Better to earn money sometimes than not.

PQs and even quests are great places to get some good items at times if you are seriously on a budget. Slippery Shoes, Mushking Glove, Goblin Cape, etc. have nice stats and are often better than most stuff you can find or forge at times.
