I suspect Larian is using levels for all the RPG gamers out there who need to know how awesome they are for having beating a level X creature. The creature levels do not match with their D&D CR, so it's pointless information, even more when they buffed certain creatures anyway.
For example, Haslin is not a level 5 druid. He can cast spells while transformed into a bear, that means he is at least level 18th. His HP match a level 18 druid too. You can take have him as a temporary companion to clear the goblins. I suspect many people would complaining if he read Level 18 or CR 18 instead of just level 5.
No, no. level 18 is when you can cast spells while transformed by beer. Otherwise spot on.
