AAE is my favorite encounter add-on, sadly, it uses PC Level Mult which override my change, so this version set a min max level for each mob of AAE Normal version. This is a BETA version, feedback needed ! (You need Main plugin tailored for AAE)

Just a csv file which list Min / Max level of Edited Skyrim Encounter Zones

Install as usual, put it at the end of your load order.
Need more tweaking not recommended to be used but if you are curious or want to help ;)
