Seemingly that if u can catch urahara and kill the IH i think if u should fail on the 33% chance of controlling your IH the kido's u have should still be usable! but if u fail on one of the first 2 u should lose them!
PS) besides ive never seen ichigo roll a dice in the anime series for getting a 33% shot at becomming it so why not buffing up IH, let it also shoot Getsuga's and remove the % thingy and make the lvl req for doing Vai -*test*-('") lvl 300
you lose kido anyway even if you become a vai last time I checked its part of trying for vai
it hopefully preventa everyone from trying for vai
I like the no % and much higher req though
I say Vaizard should be a 100% chance IF you can pass all the -*test*-('")s. and have the -*test*-('")s all very challenging, but can be taken at any level, but if you do take it you lose kido period. (basically, make it challenging for the higher levels so lower levels are not getting vaizard, like make the vaizard next to impossible to kill.)
but why would the vaizard shoot tenshous. Unless you HAVE to have ichigos zanpaktou to be a vaizard, which im pretty sure you dont have to be.
yes becoming vaizard sould not be a sure thing no matter how higfh you are otherwise we would have the smae issue as before it would just take longer.
as far as losing kidou yes you should there HAS to be a drawback to trying to obtain hollow powers as a shinigami.
it will make u think twice before going for vai
lol i dont think twice....i mean i train hard before i get it, make a lower lvl 299 and beneath -*test*-('") withh a certain % chance and a lvl 350 and up where u only get to catch and kill and be vai for sure

cant handle a chance that you'll never be a vai? to baaaaadz
When you fail to catch Urahara or fail to kill IH you should lose your Kidou's instantly. If you do manage to kill IH you should get 33% to become Vai..
