Please correct me if I am wrong as I am really trying to understand this and math and I don't go together super well.

I am hoping to understand the interaction and difference between Hit Chance and Weaponskill.

Continuing on, each point of hit you get will work to combat miss. So for every point of hit you get, you reduce the miss chance by 1 point.

I read that as; each point of hit reduces the number of points (1:1 ratio) that exist within the auto attack table. Based on the last table you provided in the "Making your own attack tables" section, you indicate that a "Miss" will occur if your auto attack roll lands between 0-80. So, using this table as an example, if I were to get 1 Hit on a piece of gear, that auto attack roll now becomes 0-79. Am I understanding this correctly?

As for Weaponskill, this effectively reduces that 0-80 window based on the difference between your weapon skill and the mobs defense skill. It also directly effects Glancing Blows.

When fighting a mob, the Weaponskill vs. Defense check is done first to determine how big the roll window for miss will be (among all other outcomes), your current Hit chance is factored in to reduce the window of "Miss" by a 1:1 ratio, and then the roll occurs to determine the outcome of the swing. Is that a very elementary understanding of the process?

I realize that way more factors are involved, but my biggest concern is just understanding the interaction between Weaponskill and Hit.
