no offense, really no offense, but first, do it, create it from scratch, and don't just take something ready-made from somewhere and change it a little, and then I'll gladly listen to how "not difficult" it was.
So, some of the weapons (helmets and shields) were made by me! It took a lot of time, but there's nothing extremely complicated about it... however, creating a model with a proper UV map for further texturing is much more difficult, but nevertheless, it was done! Again, a lot of time was spent learning! And a lot of money was spent on buying thick books...
