Tamer Rank is divided into S rank > A rank > B rank and so on until I rank.
Place ranking is typical. Top 1, Top 2, Top 3 until Top 10, then Top 11-50, Top 51-100and so on until 22501 and below.
The rewards for each ranking can be viewed in-game.
Now let’s get to the juicy part!
In other words, using the same example, you finish a season at Tamer Rank A, you can continue to climb towards Tamer Rank S. You don’t have to start from Tamer Rank I
And once you hit S rank, you will stay as S rank forever and receive a minimum reward of 50 rubies + 20 BP coin every week.
As long as you play at least 1 PvP battle every week, you will receive the Tamer Rank reward.
However, even further into the future, the BP shop will sell Target Plugins for MEGA Digimons. These are almost must buy, the boosted stats they provide can even bring a power crept Mega back to top tier.
Not only that, some newly released Mega will have their Target Plugin sold under BP shop so if you want to maximize those Megas, you will need to buy the Target Plugin.
Each Target plugin cost 250 BP medals and each Mega has 4 Target Plugins. A total of 1000 BP medals per Mega.
The same placing bracket is used for Digimon ReArise JP version. The amount of players obviously differs from JP. In the JP version, you are only competing among players from Japan and maybe a small amount of non-Japan players. However, the global player base will be much larger due to it being players from all over the world.
Let's put JP ReArise at 50k active players and Global ReArise at 300k active players. Getting top 3000 is JP is definitely easier than getting top 3000 in Global.
Although you don’t lose points when losing a PvP battle, you still need to keep grinding until you hit a Placing that you are satisfied with.
Beware of players ‘last-minute refresh’ at the end of the week, which will put your placing much below what you expected when you opened up the game the next day to claim your reward.
