I'm making the item, equipment and magic system for my game, and man... how boring it is to register each item, magic or equipment with name, damage, effect, description and so on. Unfortunately there is no escape, it is necessary to do it one by one, and there won't even be that much to register, but for those who are immediatist and want to move on to the other parts of the development, the anxiety appears like a punch in our face.

I hear ya.  When I was building an inventory setup for my low kb rpg, I had to be careful in ensuring that each byte spent counted for something.  I ended up on settling on 16 bytes per item: 8 for the name, 8 for details, like cost, damage, etc.   For most equipment I ended up settling on a progression setup where each piece was more beneficial than the last, but the cost went up considerably.  Since I allocated one byte for cost, the number was multiplied by 25 to give me a max. price of 6375 for an item, so my chest and enemy gold drops reflect that max.   If anything costs 0, it's a special item and it gets special treatment like, "It can't be sold or dropped".

Honestly though once you get  to the point where you're just spamming item descriptions into your game then you've finally made it to that part of game development where you can focus on adding content - and that's great.  I was once really bored of adding random items to my game, it felt like a total chore, but once I started thinking about how easy I had made it to add items then I realized that I could start experimenting with greater game design principles and exploring the design of my project a lot more deeply.
