This category is also known as the "knowledgable category" meaning some people know of it, but not all.

And sorry for this part coming out late, I tried to post it 2 days ago but got disconnected.

Sword of chaos: Go to the elevated land east of Glenborus (dawarven town) move the boulders to reveal a cave, inside will be the sword of chaos.
-------------------------------------------------------------------------------
Shoes of the scorpion: In the 4th level of the catacombs, enter the big hall to the east, open one of the tombs and inside will be the shows of the scorpion, note: A scorpion will attack you when you open the tomb.

Boots of the vampire: Go inside dark cave and into the vampire part, there will be a locked chest there, look inside the coffin and take the key, that will open the chest which contains the boots of the vampire! Note: The vampire will attack you when you open the coffin.
-------------------------------------------------------------------------------
Verlat's ring: Heal Verlat in Aleroth, (still happens if you heal both soldiers) then when you reach Verdistis much later in the game, walk up the path to the left of Leptines store I think, Verlat will be there and he will give you a ring!
-------------------------------------------------------------------------------
Singing blade: Pedro will drop it when he dies.
-------------------------------------------------------------------------------
Sword from the stone: Pull it out of the stone in dark forest, unfortunately, it must be returned, but if you know the duplication cheat you can get a copy of it.
-------------------------------------------------------------------------------
Halberd of the rock: Found in cursed abbey in the northeast corner of the entrance hall, it drains your stamina even if you carry it, so either drop it, sell it, carry LOTS of stamina potions, or wait until you have lots of constitution (gives you stamina and hp)
