How to get my stand?

There are 2 ways to get your stand. The first way is to get stand discs.
Right click/long press the Disc to summon your Stand.
And the skill of the stand will show up in inventory. To use them, right click/long press.
The 2nd way is to use the stand arrow. You can find them in suspicous sand, or trade them with Rohan. He spawns everywhere.
Right click/long press to use the arrow. If you are using the normal one, you will possibly get your stand, or get withering.
And if you don't want the stand anymore, you can use the item 'Stand Disc Remove' to recycle it.
Right click/long press to use it. After using it your stand will be collected into a Stand Disc
