Natural skills

[Konohuro]

What about having another skill-tree, a simple one which would contain: Hearing, Vision, Smelling and Hiding. Every player will have to spend a certain amount of points on those skills from the beginning of the game without any progression unless he gets rank-up (then he will get more points to put on what he wants). On the other hand, what those skills do is more complicated.

1.Vision- something similar to the Eagle Vision in Assassin's Creed, but you can't see clearly the objects. All is black unless another player is hiding. If you have enough points on this skill you can see the position of that player signaled by a red area, however you can't move while using this skill so you will have to turn it off and go to check. When you put more and more points on this skill your Vision will have a bigger range and you will have a bigger precision, Oh yes, I forgot to tell you about precision. Things won't be as easy at the beginning, the red color that indicates the area of the player will be really big compared to the real position of the player, you will see a red area like 5 times bigger than the character size.

2.Hearing- very similar to Vision sense, is a detecting skill. The difference is that when you use that skill, there is no black screen. On the other hand, you can't move nor using camera rotation. If someone is nearby, on the screen will appear some arrows that indicates his direction, simmilar to shooters, when you get shot by someone some red arrows appear around the screen like here: (here would be 2 players around you as there are 2 indicators). Also here, when you put more points on it, it will increase your Hearing range and precision. PS: the red arrows or semicircles won't disappear but they will palpitate.

3.Smelling- Unlike the others two, this is a tracking sense/skill. While using this skill, everything turns black, you can see only the contour of the objects around you and a red way that shows the traces of the player. While this skill is on you can't run, you can just simply walk, so if you are in a dangerous place alone, you would better use this skill for some seconds to determinate the main direction. The whole image will look similar to this:


4.Hiding- This skill is a passive one. Depending on how developed is this one and depending on how developed is the enemy's detection skills (1 or 2), they won't detect you or, they won't have such a good precision as they would have if your hiding points would be 0. In few, this skill is the one that counteract the first 2 senses.

I think damn near everything mundane could be incorporated via the Natural Tree.
Athletics (Strength-Speed-Dodge), Chakra Charge, and Lock picking for example
