Does anyone know what locking or unlocking your past even does? I can't find anything online and I "locked" my past and it didn't seem to do anything.

Hi, I got the despair achievement and my character is now burned and can't wear armor, how do I cure this status?

Title.

Hi, as per title, I'd like a clarification about [locking/unlocking pasts], please; if I'm not saying a major BS, one way to unlock a rare Past is to kill a boss without been hit, right? My doubt is this, if I unlock 2 more of them, will I be able to choose which one I want to use/lock at the NPC, and 2nd if I die 2 times in a row while I'm carrying a are past, will it be lost forever or once I've got it, it'll go into some kind of special store? Thanks in advance for your time, replies and patience....
