Actually, for this upcoming update I'm going to lower the frequency of when the earlier mob enemies use the bite attack slightly. The idea behind the bite skill being so deadly is that I want even weaker enemies to be a potential threat and to teach the player to always be prepared. While playing the beginning chapter, did you find the slime ranch that gives you the ability to grind for money
Yes, I found that and grinded about 20 slimes early in the game and more later. To be honest, it's been a while since I've played. I don't remember everything. It could be that I preferred buying armor over consumables. I guess then it would be my fault that I had to be so worried about being infected, but I simply value general upgrades more than something I have to use up against a weak enemy (especially when that can be avoided with save scumming). Unless I am mistaken my first reaction when fighting one of the ghouls was surprise at how much damage they dealt. Not that that's bad, but it would explain why I wanted armor so desperately, especially with multiple (mini-)bosses on that mountain.
But decreasing the frequency of the bite attack early on would probably help. Of course, there's the possibility of it having the opposite effect in a few cases. Some players might end up using most of their holy water on the way up the mountain because it feels like a rarer occurrence, and then they have less for the bosses.
