Can other players kill me and loot my items?

I played softcore and was invited into a public game to do Baal speed runs, but worried that someone might try to kill me and loot my items. Is it possible?

No, when you die you'll drop a corpse, and you're the only one who can grab it. You can either get back to the location where you died, or you can quit and join a new game, which will cause the corpse to move to your spawn point in town.

No one else will be able to get your items from your corpse.

In earlier (like super early) patches of the game there was a mechanism where you could drop items upon death, but that was fixed.
