Posts ending in 「0」 and 「9」 become Ripple users while posts ending in 「1, 2, 3, 5, 6, 7」 and 「8」 become Stand users. Posts ending in 「4」 do not survive the Arrow. 「Doubles」 are also Vampires. 「Triples」 have one the Corpse parts in their possession. (0 → Skull, 1 → Heart, 2 → Left Arm, 3 → Right Arm, 4 → Eyes, 5 → Ears, 6 → Spine, 7 → Ribcage, 8 → Left leg, 9 → Right Leg).
>1 → Close-Range Stand
These Stands are known for being able to inflict powerful attacks or deal close-range effects, with destructive power or speed normally ranking between A-C. However, they are only able to move small distances from their users and/or have short-range attacks or effect radius. These Stands will generally follow their user's will.
>2 → Long-Range Stand
These Stands also follow their user's will and are capable of long-range movement. These Stands tend to have ranged attacks and/or attack from far distances between them and their users, which is why most Stands of this type are typically ranked A in range. On the other hand, they are generally unable to defend themselves in close-quarters combat.
>3 - Bounded Stand
Some Stands may be bounded to tangible objects such as vehicles or even sand instead of showing their true form. Said Stands, if bound to fluid objects, may even be intangible. These Stands can be used as equipment and can be seen by ordinary humans. Although most of them vary in terms of statistics, they commonly have medium-to-no development potential due to these Stands only being able to perform their set abilities.
>5 - Ability Stand
These Stands grant their users a superhuman ability of their own. The Stand user uses the ability without the Stand itself appearing corporeally, as the Stand is bound to the user's own body. Ability stands typically rank A in durability, because they do not take damage themselves and can only deactivate if their users are incapacitated.
>6 - Automated Stand
Automated Stands are Stands that act on their own. They follow a simple objective without directly obeying orders from their original users, though they can be preset to follow orders before they are activated. Said users do not have to be present for the Stands to do anything, as these Stands are known for having a range that is close to infinite. Also, due to the Stand being automated, if the Stand takes any damage, the user will not receive any damage at all (in most cases).
>7 - Combined Stands
Combined Stands refer to Stands that have merged their abilities with other Stand abilities and as such, result in a Stand which is able to use a mix of different abilities. These Stands are the least frequent type of Stand to appear in the Jojo universe.
>8 - Evolving/Multiple Forms Stand
A select number of Stands have the inherent ability to evolve; becoming stronger and allowing their user to use the Stand in different forms with new/different powers. Unlike "Combined Stands", they are not necessarily able to use all their different abilities at once and may only use certain abilities per form.
If a Vampire post follows after a Ripple user's post, the Vampire dies. Stand users are attracted to each other so Stand users with the same last number must fight, the winner is the poster with the highest last number in the time of their post [(Sun) 22:36:44]. Corpse parts owners must fight each other, the winner is the poster with the highest penultimate number in the time of their post [(Fri) 15:16:20]. The winner also gets to keep the loser's Corpse part.
