According to UESP, many factors determine this number. What I don't understand is the "how" part.
I know there are things in the game which can have higher ratings than what we can make. I just came across a green staff yesterday with a base on 1200, while my character with a Ruby Ash staff with Rosin only manages a "max" of 1092.
So how is this possible? This isn't even a Vet item. It's just something I found on a lion.
I tried researching this on my own, but videos and guides only talk about getting the "best". I'm not looking for the best. I just want to understand so as I craft my own stuff, I can learn to build what works best for my character's play style.
Oh, I should let you know my current character did not create the staff. This was done with an alt who has maxed out stats. I created the staff with her, and gave it to my current character. The damage output changed immediately (I expected this), but that's why I'd like to understand what elements changed the base.
My current character is a sorc, but I 50/50 the attributes to magicka/stamina, as I didn't want to play another pure sorc. I switch between DW and Lightning staff, depending on the situation and enemy I'm up against. I do know this has a major impact on damage output, but I feel I make up for it by using the right weapon on the right enemy. This isn't for end game play, just solo PvE stuff.
A link to actual information or few examples would be greatly appreciated, just so I can take it from there. I fully intend to learn as I go, but without the basics... I feel lost.
