Beware. Due to the server crashes that occur each day in same time, people can abuse that on the unid items.
How does it work?
Before server crash (3pm my local time) people identifies items and check stats. If the item has low stat, they are waiting in game and wait for server crash. After the server is back, there is a rollback, so all those items become unid once again. Of course the good items are choosen by players and identified once again, as all stats stay with item, once dropped.
Works well with unid torches, annis, uniques and others.
When you are about to buy unid torch, don't even count for sorc torch
Yes, I do like conspiration theories.
