So, adventure mode is getting cooler. Especially with the new world generation stuff. You can really start to do stuff, effect things, etc. And it's going to get better.
My main gripe is, you die really easily. Yes, it's realistic, and yeah, losing is fun. But playing is also fun, and right now that's a little hard to do.
At the start, you tend to die very easily. Even after you train yourself up for an hour of real time. The problem is, unlike most games, there really is no difficulty ramp. AKA, from the start you can end up facing super-strong enemies, and dying. While it's sometimes cool to be wandering around and suddenly end up fighting an impossible to beat match (THREE ORGES- and one of them is BLINKING). Or taking a quest and ending up in a cave where you are horribly raped.
So, my suggestion is, Plot Armor. Plot Armor is an invisible stat, only for player characters. What it would do is, well, give you extra "Lives". When you would take a mortal or really bad wound, it lowers the damage (But does not remove the damage), and uses up some of the plot armor. Plot armor recharges slowly over time, maybe one point a day, to a max of three points?
This wouldn't save you from death, of course. It would just save you from instadeath, give you a chance to run. The effects should be very subtle.
TL;DR Version:
No "beginners" area in adventure mode. You can end up running into impossible to kill creatures. Suggested solution is plot armor, which lowers damage from a Mortal Wound to a Bad Wound. Plot armor is used up, but recharges slowly over time.
