1. The probability of hitting equipment has nothing to do with your level, but mainly depends on the attributes of your equipment or amulet. People who wear this kind of equipment ... have a better chance of getting magic equipment. Level 28 doesn't have much good equipment under normal difficulty, but it can be a little more in nightmares.

2. It has nothing to do with the above level, but I suggest you play in the difficulty of nightmare or hell, and there will be more opportunities! For example, I still have nightmares at level 75, but I can also use game modifiers. I can make a piece of equipment with it at will, and I have a 500% chance to get magic equipment. I can also make all kinds of equipment directly, but it's too boring to use. I'd better play by myself.
