Weapons that are crafted will get a random bonus to attack, in part influenced by the skill of the crafter. The material used to craft the weapon has no impact on this bonus. Using an higher grade material for crafting, will result in an item with an higher durability.
Maximum Attack bonus from crafting skill: 50%
For shields it works in the same way, but instead of a % increase in damage, they get a bonus to the armor value (up to +3). Again, the material used isn't a factor in this bonus, it is used only to increase the durability of the shield.
This guide will help you raise your crafting skill to 100.
If your skill is below 30.0 it's recommended that you purchase training from a NPC Trainer for 300 , which will put your crafting skill to 30.0 and save you time and resources.
A general rule of thumb is to craft items which required skill is between 5.0 and 15.0 skill points below your current skill. You're able to gain skill on any item which isn't Trivial to make, meaning you have a 100% chance to craft the item. An item will start to get Trivial when your crafting skill is 25.0 points above the required skill level. To save on resources, craft the cheapest item within this skill span.
During your crafting sessions you should at all times check available work orders since these will grant you some resources, money and recipes. They're also a great way to clear out your storage space from the abundance of crafted items you'll be getting.
Another suggestion is to craft whatever items you're able to sell to other players at a profit, compare how often you're able to craft the item and the cost of the resource to the worth of the item.
The crafting difficulty of the carpentry items have been changed many times during the early access, right now you can get to 100 skill without using expensive resources like Ash or Blightwood. Wood Warbows will take you up to 100 skill, making getting to 100 quite a lot easier than in the past, where you required Blightwood Warbows for the last 5 points.
Blightwood Boards are really expensive materials, don't try to make them before they are trivial to raise your skill, there are much cheaper ways.
This table is an example of a possible path to 100 with minimal resources invested.
