it sounds like a good idea, fun and competitive. but to get master you would probably have to only train lightning(or whatever nature you are going after) and this would be a bad idea because you would be vulnerable to wind style users... but if you want the fame of it then i say more power to you and good luck!!!

Jutsu Name: emergency evac
Jutsu Type: ninjutsu
Jutsu Description: this works similar to a transportation jutsu.you must next to a motaly wounded shanobi, must know medical ninjutsu to learn
Jutsu Level: Novice
Chakra Nature: Yang Release
Jutsu Range: short
Effects if hit: you are transported to a evac location marked with a tags with the formula on them.  this must be set up before the jutsu can be used

i saw this and i wanted to bring this topic up because it is kind key to learning and executing jutsu. and something like this should be added to the current build when
you're ready to address trainable stats

a real simple way to do this is with a physical energy bar(stamina PE)
and a sprite energy bar(SE) experience in stats gets turned in to energy for these bars. see later posets(edited)and
chakra control(CC) levels :(edit- experience in this as well)
cc level mod-
.1           LV1
.2           LV2
.4           LV3
.8           LV4
1.6         LV5

PE 2000 to start
SE 2000 to start
total chakra at chakra control level 1:
 level 1=you learn to mix PE and SE to make chakra here is the equation:
(X pe+(SE x .33))cc level mod=desired chakra in bar- so if
chakra bar cap is 200 then
(1340PE+(660SE)).1=200 max molded chakra - use beginner jutsu
if you only train in chakra control then
(?PE+(SE.33)).2=400 chakra        level 2  level 1+ novice(tree climb)       
(?PE+(SE.33)).4=800 chakra        level 3 level 2 + intermediate(walk on water)
                     .8=1600 chakra       level 4  "      "    expert(your choice form or   
                                                                   nature change)                                               
                      1.6=3200 chakra      level 5 "       "    master(your choice form or
                                                                    nature change)
(these figures are only to illustrate the idea and do not represent actual game play figures, you start with a chakra bar value for the cc level and work back from there
i suggest this because we currently have a chakra bar value.)

remember that PE and SP are also trainable so the amount in the chakra bar should be a percentage of both...i will explain why in a min, but the mix should favor PE at least 2-1
and should cap out at 33% of SE. the same factors determine what jutsu you can successfully execute based on your current level of chakra control... this implies the level of concentration needed to execute that jutsu as well as provides a scaleable value for chakra.with PE and SE trainable the chakra bar will grow exponentially. IF YOU RUN OUT OF EATHER SE OR PE
PE- YOU FAINT
SP- YOU DIE
this is why i added a PS at the end- but briefly it mentions molding chakra- by using 33% you insure you cant kill yourself by recovering chakra

this would also allow for taijutsu to use PE and only slightly affect chakra reserves. regeneration rates for PE should be based on stamina stat below and should continue to regenerate the total amount of the stat per sec but only while standing still. so long as you still have SE. this is to insure fast battle style.... sense the less PE a person can recover because of dodge,block or attack the more damage they will take from a weaker endurance(see hit point debate in suggestions and the equation in character stats below)

SE should only recover after you sleep or by an item. so after a battle chakra could only recover to the amount of SE you have left.. so using 33% you can replenish 3 times, either manually or not, before sleep.

(eventually i would like to see the regen rate for PE drop if you fight with low SE to long but for now we will keep it simple)

although with this set up it may be technically possible to learn all 5 chakra nature with each chakra control level i believe no more than 3 or 4 should ever be able to be mastered simply for game play and teamwork reasons.
The only exception to this i believe would be if you at the beginning of the game you inherit the village legacy then all 5 natures may be possible.
But i  like the current chakra nature plan, this gives you the option to learn more if you want.

also i believe each one of these should be the main focus of a specific type of jutsu

Taijutsu would require a higher PE value to execute combos and can be done at low levels of chakra control- my even only require PE! if they train in high enough levels of chakra control yin release ninjutsu and low level genjutsu may be available.

Ninjutsu would requires both SE and PE to master and require varying levels of chakra control based on the skill needed for the jutsu and chakra consumption. here is where you can add yin and yang release to the mix...literally... a yin release would use more SE than PE and a yang release more PE than SE.

Genjutsu is tricky....it doesn't require much if any PE at all It is solely a Yin release. however unlike ninjutsu the level of genjutsu are based on your chakra control and do not take as much chakra to execute. however since SE does not recover like PE it has its risks. but this is also why i believe genjutsu can be strong. and so they are not at a complete disadvantage maybe there should be a tree skill that converts PE to SP at a rate of say                10  -  1 to start trainable, also this means less pure chakra to us regular ninjutsu to attack with, only yang release attacks should be available to genjutsu users.

for this system of jutsu to work- basic jutsu that wont use much chakra can just function off of the system in place now.but high level or yin yang release jutsu will need to be programed with a PE and SE consumption value! In order to even be available, the caster must have at least the programed PE and SE +1 values in there reserves and the requisite cc level to be able to activate the jutsu .since i only expect there will be a chakra bar in the upper corner, a list of jutsu you know at the bottom of the screen( you can still activate with the reserves of PE and SE you have )should be available so you know if you need to address a stats level in battle. through items like medical herbs-food pills or adrenaline.

this whole system can be worked back from the chakra level you already have in the current build. (cc level mod-.1 LV1,.2 LV2,.4LV3,.8LV4,1.6 LV5)(X pe+(SE x .33))cc level mod=currant chakra in bar- after you get the values round PE up to nerarest whole number and SE you need to multiply by 3 and round up to nearest whole number.
all skills can be worked of a % final values or current values of PE and SE and chakra control levels- each CC level should be assigned a numerical value for each level.

so here is what i think a character stat sheet should look like after creation:
health: set value
endurance=beginner (Total PE available)x.1=damage reduction
Total SE Stat=____- Intelligence, charizma, Imagination
           optional %'s   40/30/20    30/40/20    30/30/60
Total PE Stat=____strength,     Stamina,    dexterity/block.
           optional %'s 60/40/30    20/30/40     20/30/30
CC=level 1
chakra bar total:________
tree=ninjutsu
chakra nature= wind
scenery-none

      ninjutsu
      taijutsu
      genjutsu

       tools
       consumables
       mission items

       organization


I apologize for the length of this  but i just want my ideas to be as clear as possible.

PS.i know that no one wants to have to mold chakra manually
but with this system it does not need to be that manual. one key could activate a animation of a one hand sign that simply does some math to fill a chakra bar, based on your chakra control level..

if you are not moving to do this PE regeneration can work at the same time. i suggest that this can be done while moving but one must be careful because you could pass out...potentially... if you run out of PE

this would be advantages for 3 reasons.

1. stealth- most scenery ninja bass there ability on sensing chakra-
no chakra means blind- so i propose a way to discharge all molded chakra
just one keystroke to bring chakra bar to 0.and reintegrate resources back to reserves.

2. ninjutsu can use less premolded chakra then if activated without it based off of the level of chakra control.

3.spending time molding chakra gives you another way to train chakra control

here is how a ninjutsu could work without premolded chakra-
CHIDORI jutsu info
master level jutsu-cc mod 1.6
molded activation 200 chakra (number from 1.0.8 version)
unmolded activation 150 PE and 100 SE= 400 chakra
needed unmolded+1
IF  3             +                  9                 +                   8  =molded(out of
                                                                                                  chakra)
then 150 PE       +         100 SE    =      250 TE    x      1.6 cc =unmolded
                                                               Total Energy
using a simple if then code you could make pre molded chakra the default source of the the jutsu and  unmolded the back up so long as the character has the unmolded values +1 in reserve. as you can see in battle it would be twice as hard or more to mold chakra and activate a jutsu then if activating it out of molded chakra. because of the added difficulty of programming these jutsu with this ability maybe only high level jutsu should have this ability to start.  Again the values here are only for illustrative purposes testing would be needed to get a balanced game play. this should also be a learned skill based on intelligence.

lets look at all the things that would have to happen for that balloon thing to kill a jonin player @Shivraj.

1. MUST BE IN A KILL ZONE...
2. you would have to be caught of gaurd or not paying attention in a KILL ZONE!!!!
3. all your defences must be down..... IN A KILL ZONE!!!!!!!!
4. you must be in a kill zone alone with no medical ninja in your party- the only likely thing in the list!!!

now as for medical ninja in a party- they would likely be monitoring a battle in a kill zone very carefully

after substitution jutsu activat and other defensive jutsu go down(at jonin level this would take some doing) and your team mate goes down!
i imagine  a smoke bomb activated by the medical ninja  that allows you to go in and extract your team to a near by point pre set up.. this would require stealth and timing on the part of the medical ninja as well as planing  the extraction point ahead of time... all things you would likely do if you were entering a kill zone anyway.here the medical ninja can administer first aid and evac to the nearest hospital.
as you have all said this dose not guarantee that you will not die but it is not as easy as you all seem to think it will be.

even a one hit kill jutsu that connects with substitution jutsu does no damage. and obviously  a wind style shield would be very effective against a jutsu like chidori.  just because a jutsu CAN be a one hit kill dose not guarantee that it will be a one hit kill.

i have one other suggestion to make things more interesting too...

what if jutsu like substitutions and other defencive jutsu(low level) can be captured in a cue at jonin or even chunin levels...
since by the time you hit those levels those elementary jutsu should seem   second nature to execute. you would still need to wave the hand sings but it would be captured in the cue and activate on contact. freeing you up to attack with another jutsu.

for instance lets assume you are attacking with chidori but are worried about a counter attack,

substitution 123
chidori 874

by waving the signs 123874

the substitution is captured in the cue and chidori activates
IF... they counter offensively with a ninjutsu  or other close range chakra based attack the fight is pretty much over... chidori will connect and depending on how high a level you have trained that jutsu it could one hit kill. and how awesome would it be to see all the hard work( of raising your chidori to that level)pay off when they drop after one hit!!!

however IF.. they have a substitution of there own active and they counter with taijutsu or other physical attack then you as the attacker should look out for a incoming attack.. be ready with a block, dodge, or some taijutsu.
many options from here.

and so battles will be decided by the skill of the player, the jutsu you use and being able to decipher the opponent's jutsu, strengths,weaknesses, and possibly more important there fighting style. the people that pick this up quicker will have a bigger advantage. I do not believe that just because you are a higher level you should automatically win over a newer player (while i do agree that you should have a advantage and your battle experience should be much higher). take every battle seriously.... or don't fight.

if we can pull this kind of battle format off it will move this from a simple
mmorpg to a massive multiplayer online role playing simulation.

@Tameshi Hinode every mmoropg i have ever played has never cried about realizem!

i may be the only one that is thinking this way i don't know but in a game with medical ninja i don't see why there is all this fuss about perma death unless you play recklessly then i could see you getting upset but in my opinion  this game should not be just about mastering ninjutsu, taijutsu or genjutsu it should be about strategy in battle too.

@Reminance i would hope if you worked that long and were about to loose in a permadeath zone you would have the presence of mind to retreat from battle but i don't know maybe that thought never occurred to anyone

@Sanji RP=Role playing a story about a your character or your clan this is usually a limited multiplayer experience.

@Shivraj  the only thing that made me think about bloodlines is that is canon to the
naruto universe- no one out side the hyuga clan was ever born with a byakugan same with sharingan or any kekkei genkai- if its not a bloodline trait i would recommend these special abilities be called something else to avoid this kind of confusion.

but this is not most mmorpg's in this game concept its not about getting better gear- and training your character in regards to how much damage you can take is not real either-
reality is what we are going for right!!! if you train your body for 7 months you will increase your survivability through evasion and experience at jutsu but not the amount of damage you can take. if a kunai could kill you before the 7 months then 7 months of push ups does not make you immune to a kunai attack.
