Yeah, thanks.
And surprisingly awesome the creator shows up. That's always cool.
1. Normal stuff, easy to build with materials. Ex. doors, walls, frames. Probably most static stuff, medieval weapons, etc. You will rely on stone daggers a good chunk of time
2. Hard stuff, has a penalty to craft with materials. Ex. Catapults, engines of non magical nature. Anything that can substitute mostly metal stuff. Mostly armor, pole arms, bashing weapons.
3. Advanced stuff, can only be crafted with metal. Ex. Proper swords, and metal armor. Materials can, and will be mixed somethimes to minimalise the costs in metal.
4. Powerfull stuff, can only be crafted with metal, with a little penalty when someone is unskilled with necessary components handling, uses a little of components. Ex. things bordering on magic such as poisoned sword, or sword that somehow manages to give off electricity, but no magic was used
5. Magic stuff, cannot be crafted unless you find some components. Now this means anything really. While this are things made from components, nobody said they have to be *actually* magical, or need wizards and priests. For ex. healing potions use healing components, but once a person is skilled enough in making them, no extra effort necessary to make them. Expect flaming swords and the like
Everything 3 or more difficulty will need knowledge (a skilled person knowing what has to be done), and crafters, or wizards working on it. Note that many devices will require eg. a metal part and material skeleton, thus requiring metal and materials, and having wizards and/ or crafters working on it.
Wizards can only work with components. Crafters only with materials, and metal.
Materials is most versatile of resources, it can be ropes, wood, stone, bone, anything that's fairly common
Metal is obviously metal.
Components, is something that has no visible use, but you have to know it is usefull. This means, mushrooms, brain of a certain lizard, a fang of a certain carnivore, anything you could see going into a cauldron and so forth.
