Heya guys
So here is a video that I found really helpful as it cleared up a few points for me. For example, I had thought the knowledge rating you get about monsters could increase the more you kill.. apparently not.. You get a knowledge rating only once per mob as you gain the rating and it's all rng. Also, health experience is granted by eating food, not just by leveling up! Who knew? There are a few more nice tidbits in the video (there is so much to this game).
enjoy :)
