It does make sense to make it so Rhaenyra gets progressively less and less stress per kill as she, well, gets used to it.Also do note that I'm not gonna give you stress hits every time Rhaenyra kills someone but this was Rhaenyra's second kill and the first one she had real time to think about before doing this deed.
7 is a lot less than 30, after all.
