How do rewards and transfers work in DMM mode?

[WilliamHHunter]

Hi everyone,

If I open items like pets, Infernal cloaks, arrow kits, Blood Torva ornaments, or other non-tradable items during the season, will they transfer to World 45 afterward?

I'm also wondering if items like ornament kits or badges are retained or if they're all deleted at the end of the season. Does anyone know how that works?

Thank so much!
