Hello, how works jerarqui system?

I mean if char later will be deletad or it go to main account, sorry for nub question, i just bought this game xd.Got d3 and d4 already, and d3 was nice but wanted to try something i played when i was a child.

jerarqui system = ladder mode

Ladder is the same like “Season” in Diablo 3 & Diablo 4.
Ladder chars will be transfered to non ladder, when ladder ends.
Items in stash will also transfered to non ladder, in additional “remove only” stash tabs.
