<p>Hey Core, that's a good question!</p><p>I don't recall ever seeing an official statement by CipSoft talking about changes on item stats around that time. Looking for it again didn't result in any findings. However, I was able to find a good estimation for when it happened by using the archived pages of World of Tibia (WoT). Here's what I was able to find.</p><p>All the menioned items, except by the demon helmet, still had their old stats on August 14~27, 2002 in WoT. The new stats were already there on November 4~15, 2002. Therefore, it is safe to infer that all of these items had their stats changed on the same update. The gap between the archived pages leave us with two possible game updates: 7.0 (August 28) and 7.01 (October 22). Since Update 7.01 was just a minor update, it is unlikely that it was used by the devs to balance item stats. <strong>Thus, it is safe to assume the changes happened on <a rel="nofollow" href="https://tibia.fandom.com/wiki/Updates/7.0">Update 7.0</a> when the new client was launched.</strong></p><table border="1" cellpadding="1" style="width:500px; border-spacing: 1px;"><tbody><tr><td

href="http://web.archive.org/web/20031217084817/http://tibia.gamigo.de/library/items/item_en.php?action=1&cat=11&order=langname">December 17, 2003</a> and <a rel="nofollow"

The only update that took place between these dates is <a rel="nofollow" href="https://tibia.fandom.com/wiki/Updates/7.21">7.21</a>. This was a system update which is unlikely to have changed any item stat. Since the last archived page with the old stat is from one day after the quest system had been implemented (<strong><a rel="nofollow" href="https://tibia.fandom.com/wiki/Updates/7.2">Update 7.2</a></strong>), it is likely that the fansite staff didn't had enough time to notice the change and to update the fansite. So, we can assume that when the Demon Helmet was made obtainable it already had its current armor value (10). However, since there was no way to obtain it before 7.2, we can't say for sure that it wasn't changed on 7.0 with the rest of the mentioned items (or on any other update prior to 7.2).</p>
