Do not level STR or ACC above 1. It will raise your combat level, and since PVP(Players versus Player) and Party Quests limit your battles to have only players around your own CL(Combat Level), you will be at a disadvantage.
The coins you spend on spells are nothing when compared to your damage per second.

Do not skip the tutorial, it has almost all of the information you need to play the game. It teaches about combat, magic combat, fishing, selling items to NPCs(Non-player creatures), mining, forging, jewelry(crafting ring moulds), alchemy(crafting vials), woodcutting and a lot about your chest(bank).

DORPAT
In Dorpat's map(the first city) you can find fir, cactus, oak and willow trees. You can also find sand and silver to mine. If you go down the ladder(between the city and the outpost), there is iron to the south after some skeletons near the vampires.
Inside of Dorpat there is a ladder to mine Tin and Copper.
South of Dorpat you will find fishing spots.

SPELLS
To craft spells just get a flash medallion and some cotton fabric. Then you can go to Reval, the desert city, and in that map craft the cotton fabric into spells while having it equipped along with the medallion at the altar. Reval has the flash altar. Flash spells are the weakest, but the other altars are harder to find.
To find a medallion you have to buy one at the NPC near the ladder to the Tin veil, in the market or get this tool as a monster drop.

ISLAND
With 35000 coins you can buy your own island at a NPC in Dorpat.
You can place a chest in your island.
You can place cabinets in your island to hold more items. Fir cabinets hold 2 items each.
You can train carpentry, farming and breeding in your island.
To make a soil you need 35 small vials filled with water. Soil can then be used to plant seeds in it.
To make small vials with water you need empty vials then to click on a well. Dorpat's well is south, near the jewelry NPC.
To make a small vial you need 2 sand. Get sand with a spade.

WEAPON AND ARMOR SKILL REQUIREMENT
Weapons have ACC requirement. Armor has DEF requirement.
Mage armor has Magic requirement. Mage weapons have Magic requirement.

The market is inside of your chest(bank).
