is there any guide for beginner?
I can share my experience.
I'll start by creating a character: the choice of archetype is yours. I wanted a magician, so I paid attention to Int statues, as well as Agi (to get the move first). And black magic is the obvious choice as a starting skill. In terms of crafting skills, I would recommend taking Agriculture + Cooking. Agriculture will give you herbal picking, tree felling, farming. And cooking will give me access to crafting consumables - Baked Potatoes and Lemonade (easy to make) helped me a lot. Also, the Demoness will offer a choice of 3 things. I did not check what the ring and brass knuckles give, I chose Pet. And I was satisfied, bcs pet is quite useful in battle (by the way, I will describe below how to get another pet).
So, once in the game world, you will need to acquire all possible skills, some of them can be obtained from teachers and after quests, and some of them only buy books from the NPC that appears on Saturdays on the 2nd floor of a brothel, I will give a list:
Black magic - is the main fighting skill for magicians. You can get it either when you create it or buy a book from the NPC. If you are planning a magician, take it from the beginning.
Athletics - is a core skill for warriors. Also, this skill will give you the opportunity to better explore the inaccessible areas - hitch / jump. The skill can be obtained from the Guardian Goblin (prison + barracks, southeast of the village), after completing the quest to deliver 10 units of honey.
Agriculture - allows you to collect various herbs, wood and farm. Useful for other skills like cooking and alchemy. I heard what you can get by captivating a student, but in my opinion it is better to take it from the beginning (although, like other skills, you can purchase a book from the NPC).
Cooking - is pretty obvious. It will help you regain stamina and will. It makes sense to take from the beginning.
Mining - allows you to mine metal, stone and crystals. A very useful gathering skill. I recommend that you study it first after creating a character and entering the world. This can be done at the Goblin Miner (the mine is located in the east of the village).
Smith - various metal products, tools, weapons and armor. A useful skill, indispensable for a warrior. Can be learned from the Goblin Blacksmith (in the mines).
Alchemy - gives a variety of potions, both standard for healing and increasing stats, or for example, applying poison / arson or bombs (which, by the way, can be used by pets, thereby significantly facilitating battles with strong opponents). The skill is very useful (but more difficult than cooking at first). You can learn from the Tengu Girl Aria (from the location with the road, the one south of the Goblin Village, move first to the west, then to the north and again to the north).
Perception - I haven't upgraded it to the proper level yet, so I can't say much yet. So far, it only helps to detect traps on chests. Can be learned from the hunter (meet him on the way to Aria).
Guile - I use it mainly for covering chests. You can buy a skill book from the NPC.
Charisma - improves communication with characters - you can persuade, intimidate, bargain, etc. Helped in some dialogues (I took it at the start), but overall not the most useful skill. You can buy a skill book from the NPC.
Construction - requires other skills, such as collection or crafts for making parts, and therefore I don't think it's worth taking at the start. But it will allow you to improve the house, build different machines for production, or, for example, repair a bridge on a quest. You can purchase a skill book from the NPC.
Tailor - mostly useful for mages, needed for some other skills (like construction). You can buy the book from the NPC.
Artifice - production of various jewelry and details. The book can be bought from the NPC.
Here's a little advice for a beginner - save up some money for a start, and acquire Mining as the first skill (from a goblin miner). In addition to what is described, it will also give the opportunity to collect precious stones when collecting metal / stone. They, in turn, are both a gift for raising relationships and a good source of income for a beginner. Truffles can also be sold at a good price (at the NPC merchant in the north of the village, by the way, the assortment of goods changes every day, you can also make orders). You can get a pet - a snail this way: I first read a book about it on the 2nd floor at Aria's. To get there, you first need to improve your relationship with her. In it you will learn that this creature appears in a location to the west of the road (this location south of the goblin village). The place of appearance is a ford across the river, next to the place where the Copper deposit is located. To tame - you need to have cabbage in your inventory and not have salt (there will be an option offering to drop all existing salt).
I hope this somehow helps, although I note that these are far from all the options, since for example there is still the opportunity to work in a brothel (which I did not do) or, for example, with Aria after completing her quests. Then I think you will figure it out for yourself, good luck!
P.S. - sorry for my bad English =)
