Rules for Consideration
I was reading the SRD and found the section on Unchained Rules where I read up on the Automatic Bonus Progression. That led me to a long Google search and I found a variation that I thought was pretty nice. It would certainly free up slots for magic items that are very hard to find or come by due to not being anywhere civilized at times. Let me know in this thread what you think or if you have other suggestions.
