Q: Can we have dual elements? (I.E. Can my weapon be two elements.)
A: No. This...MAY change later on, maybe. The closest you can get to a dual element for now is the ice/snow type since they seem to go hand in hand within the series in the first place.
Q: What IS an element?
A: Basically, it's the power of your weapon. Some have no element like Byakuya. Some make their wielder stronger (like Ikkaku). It extends over a large variety of things. Fire, Ice / Snow, Water, Nature, Earth, Poison, Reiatsu. Those are just a fraction of all the available ones. Be creative!
Q: What about Gravity or Time?
A: No to both of them. You cannot make them. Do not ask. Do not say you will not be OP with them. Just avoid them all together.
Q: How can I obtain Bankai or a complete Fullbring or the Final Form for Quincy?
A: If you're at least captain level in strength, then you'll snag it from the get-go. If you have to work for it, then you will have to obtain a set amount of points before you can go down the path to obtaining your complete power. Note: Complete Fullbring will require at least one other human who has a complete power to oversee this.
Q: Why can I only use Bringer Light if I have a Complete Fullbring?
A: Because Bringer Light is a sign that a Human is coming into mastering their power. You can't just get your Fullbring and be all "Oh look! I'm a master!" And even in the developed stage it's not quite there yet. So think of Bringer Light as a reward. Besides, until then it's not like you cannot keep up with the Shinigami, Quincy, and Arrancar. There are ways. Just think outside the box.
Q: How can I move up in ranks?
A: Reach X amount of points. After that, speak with your Race Leader. However they decide to handle it is how they decide to handle it. However with Shinigami there are only three ways to go up.
