Which items existed visually but the use for them was added after a long time?

I remember there was nothing known about Hammer of Prophecy in the past.

Description:

 Today it dropped from the final boss Forgotten Knowledge, Last Lore Keeper. Are there more items like this?

Comments

The problem with this item and its rarity is that the Last Lore Keeper is considered the hardest boss in Tibia. So it's not usually killed, making it even harder to drop the hammer.

Last Lore Keeper is final boss from Forgotten Knowledge, not Library... please watch out for such mistakes...

@anilulka yes, I was wrong and I have already corrected it but this isn't the most important thing in this question.

Answer 1

Summer Dress  until summer update 2017
The Epiphany  Given as an option for reward when they dismissed GM's

Dragon Scale helmetwas implemented in 2004 and only obtainable until 2016

Golden Figurine  it used to be obtainable as a contest award by CIP after they were added to the loot of Betrayed Wraith

Ball Gown was added to the game in 2002 but only given to 2 people before Santa started giving it away in 2010.

Bunny Slippers  these were implemented during the summer update of 2004 but only after the winter update of the same year, when raids were implemented this item became obtainable.

Divine Plate  "First implented on the Summer Update 2008, but it was impossible to get. Since Christmas Update 2008 it is dropped by Ferumbras and Undead Dragons."

Elven Mail  "It was found during a test server in Rookgaard on May 16, 2006. A long time ago and for a short period of time this was the sprite of the Dragon Scale Mail. It was an Unobtainable Item for many years. Since Summer Update 2017, it is dropped by Ravennous Hunger."

Golden Boots:  the version when these were implemented is unknown but they were given as a present to a player for reporting a bug that allowed ppl to get a premium account for free, and those were the only pair known for a long time, it wasn't until 2008 that they changed the sprite of these and introduced them to the game as a lot of Zugurosh.

Bear Doll:  was unobtainable from 2005 when they implemented it until 2010 when Santa started giving it as a present.

Didgeridoo: "Although this item was implemented in Summer Update 2005, it became obtainable only after Winter Update 2008 when it was added to Madareth's loot.

Before the Christmas Update 2009, this item was very rare and expensive, usually owned by collectors. But after this update, it became available to buy from Cael, lowering the price considerably."

Yalahari Figurine: used to be unontainable until 2017

Demon Legs: "Before Update 8.2 these were unobtainable and therefore a extremely exclusive item, however, after 8.2 these became a reward for a new quest, making the value and rarity drop a lot"

Adding some more pointed out by yourself:

Wood Cape:  "This was an Unobtainable Item till Summer Update 2017. On such update, its armor value was changed from 2 to 3, and Earth Damage protection, Distance Fighting skill modifier and vocation requirement were added to it."

Northern Star:  "This was an Unobtainable Item for several years until January 7, 2017, when players were able to do the First Dragon Quest as part of Tibia's 20th Anniversary celebrations and loot it from a related creature."

These are some of the ones I could remember browsing through the Cyclopedia and ofc consulting on the Wikis.
