Training for bankai and segunda etapa is not something I take lightly. To gain these extremely powerful abilities, you must meet the following conditions before attempting training. Please be aware that the segunda etapa has a 10 post duration, regardless of rank.
1A. Shinigami; Become a Division Captain or become a Captains Lieutenant and have the Captain train with you (requirements for the captain are listed as number 4).
1B. Arrancar; Become Espada Trecera or higher.
Training must take place in the "Training Area" section of the forum. An admin or moderator must be notified that you are starting training as well to oversee your progress. Training is only accomplished one way and one way only.
1. Training must take on less than 5 days to accomplish. Training is denied if it takes longer than 1 week to accomplish.
2. You must make 3 posts every day of training. If this is not done, all posts that have not been made carry over to the following day. (ie. if you complete only two one day, you must post four the next day.)
3. Each post must be no less than one thousand words.
4. If accompanied by a Captain, the Captain must post no less than 500 words between each and every one of your posts.
5. The desired Ability is only accessible after the admin or moderator overseeing your training has approved it.
