Welcome to Gaia! ::

Was? What clan is this?

Shay or Jade(A faint Smile) both make pretty nice posting formats, not sure if they do it for other people, but I'm sure you can ask

Look in my sandbox, you'll enjoy the S rank techniques, atleast I think you will.

My guess would be it is just a case of poor wording, and has one of two meanings:

1. You must master all suiton jutsu up to your rank. S-ranks are technically the forbidden jutsu of Naruto, so under "normal" circumstances, mastering the public jutsu that are A-rank and below would count as learning all the jutsu for your element.

2. You must master all suiton jutsu your character can learn. This seems to be the most likely case if the general idea is to allow any class to use the second stage of the bloodline. However, since the only thing you're missing out on is the jutsu for stage two if you don't get it, then really it seems stage two might be intended for those who can master all the jutsu from scenario one.

I would bring this up with Cobra, since he's our main bloodline expert.

To answer your second question: yes, your character must have blue skin if he/she is a Hoshigaki. The good news is that we tell you to describe your character even if you have a profile picture for a reason: usually, there are differences between your picture and your RPC's actual appearance. In the physical description section, you would include that your RPC's skin is actually blue, thus allowing you a much broader range of pictures to choose from.

I might if they showed any sort of coherence with the genjutsu system. :s

Not only do they not follow the genjutsu technique format, but you've made them unable to be kai'd from (the S-ranks, anyway). As soon as you take away Kai, people are just going to be using Pain to get themselves out. It would make no sense for them to just sit there and take all that stamina drain. :s (That's just two of the issues.)

Not to beat you over the head with it, but I really suggest you re-read the genjutsu system in its entirety and edit your bloodline accordingly if you don't want Cobra to blow up in your face when he goes to look over this bloodline as an official application. XD I'm not saying he really would, but he'll give you the Cobra equivalent. The bloodline idea is interesting; it just doesn't bind well with the systems we have in place as-is.

I'm going to make Manami an S rank signature jutsu whenever I get around to it. Will be a torture one. :3

I could have swore I read somewhere that signature jutsu could be no higher than C-rank...or did I just somehow make that up in my head?
