Say I found a seed which contains an item I just unlocked, right in the first item room. What happens when a new player, who hasn't unlocked that item, plays my seed? I would guess one of the following situations would happen:

  1. The 'locked' item will be substituted by an item that isn't locked for the new player;
  2. All the items in the seed will be different, because the new player has a different item pool;
  3. The entire run will be different, including the rooms and such (RNG will derail);
  4. Nothing is different, the new player can obtain the item that is actually still locked.

Has someone tested which of these cases happens?

  • I barely have anything unlocked if anyone has a good seed to test this with. Commented Nov 11, 2014 at 17:31

The item you have not unlocked will be replaced by a random item that you have unlocked. (Your option 1.)

  • I would have thought it would still exist. Seeded runs don't count towards either achievements or unlocking items.
