Lots of experience (Encased)

We keep expensive things in our inventory (for example, "Fragments of relics"). During the trip, we often come across all sorts of merchants with 2 guards. We sell everything expensive to the merchant (we don’t give him the money!), Then we stupidly kill the merchant and for the fact that you cheat him they will give you a lot of experience, in my case about 50,000, I have a training capacity of 330. And so actually with every merchant you accidentally meet .. .
It is possible to do with any character, but I just do not kill civilians, in addition to these traders, with their often good loot and no consequences.
