Oh, I'm not joking (or maybe I am).
So you are a newbie that just started. You are exploring the vast world of HnH, looking for a nice place in which to settle. You see all these magnificent forests and rivers full of fish and your desire to just build a house and call it "home" grows stronger. But oh hey, you took one wrong step, one tiny, apparently meaningless step towards some random rock. And will you look at that? Now there's a portrait of a rather fun companion on your upper right corner. His name is boar and he was waiting for you... Waiting for you behind that rock. He enjoys chasing newbies, he thinks it's funny how they try to outrun him just to run out of stamina a second before reaching the river.
Fun. Times.
So my suggestion is the following: a newbie-friendly skill called "Climb Trees".
What would be the requisites to learn the skill?
No requisites, you can learn it right away. Make character -> learn it. Of course, you will need to gather some LP first.
What should be the LP cost?
Considering we are trying to make it newbie-friendly the LP cost should be around 50 or 100 LP.
But what's DOES THIS SKILL DO?
Well, to put it simply:
Adventure -> Climb Tree -> Select a tree -> Your character climbs it.
Can you use it all the time?
Nope. In order to be able to use it you need to be in combat with an animal. In other words, being chased around by a boar or a bear.
Ok, so what's the point?
When you climb a tree it's pretty much as if you disappeared from the map for a while. The boar/bear will have no other option but to disengage, so now you can climb down and run away.
But hey, what if people use it in PvP?
Nah. Should only work when being chased by animals to prevent abuse.
So what happens if someone cuts down the tree while I'm hiding on it?
I really don't know. What do you suggest? Lose some SHP/HHP? Get unconscious? Die from head trauma?
Doesn't this make you a wuss?
Oh yes, no doubt about it. This is the skill for the coward amongst cowards. But you will learn to love it.
