When you sacrifice an item, the room is 'locked' to this new iLevel, and you cannot sacrifice any items further. A message is output to all participants in the quest when you or another room member sacrifices an item, so there is no confusion what you are getting into when you join your buddies.
* Quest NPC HP corresponds to the room's individual iLevel, and increases by 1% per iLevel. This is a flat rate, and bosses do not have Rarity (yet!).
