Rayleigh's Bazaar

Rayleigh's Bazaar is a feature added in version 6.0.1. It allows you to trade in non-common units for Training Points, and exchange Training Points for various rewards. TP do not expire and you can store them indefinitely. Cap amount is not known, nobody has reported getting over 99,999 anyway.

Some content (characters, ships) is offered for a limited time only. At this point it is unknown if they return or how often, as of early 2017 Japan had Bazaar for half a year or so, but has not yet seen any returns, so if they happen at all, they could cycle on few month~year schedule!

Exclusive units and ships analysis

 * No. 1178 Oars: mediocre. Nothing bad, totally usable for new players, but the cost is very high, and he is not needed for any content. Discussions:

How to use
The Bazaar is a means you can primarily exchange your dupe legends and to a lesser extent RR characters for some stuff that may be more useful. There are some exclusive items available only through the Bazaar, ranging from collectible trash to very useful characters/ships.

Farming for the Bazaar is not easy. Realistically, you can farm some raid bosses or FN/story units (the latter during Drop x 2). Chapter 7 of the 3D2Y isle drops 1-2 birds worth 1 point during Drop x 2, but still, it is 12 stamina, giving you the ratio of maybe 1 TP for 6 stamina, similar to farming 10 TP bosses for 60 stamina.

You should conserve TP for the very good exclusive items, such as Rocketmen ship (not offered on Global yet, but expect it sometime in 2017). In fact the general consensus from half a year or so of Japan's Bazaar is that Rocketmen is a must, few other ships (Garp's, Barto's) and characters (Zoro, Sanji, Luffy) are ok, all other exclusives are collectibles only. For non-collectibles, Almighty Manuals are difficult to get, as are specialized Forbidden Tomes, and nobody is going to blame you for buying some, but keep in mind exclusive characters cost 10k and ships, 7.5x, so don't waste TPs if you are going to regret it later. If you know what are the best items to get in JPN Bazaar, please comment or edit this post.

Do not waste your TP on CC, Beli, Cola, boosters, evolvers, or "bad" forbidden tomes. Whether you want to buy mediocre or weak characters or ships, it is up to you and your desire to have as complete of a collection as soon as possible (and possibly your wallet).
