In an attempt to load up a level 20 character with as many boons as I could realistically give, I tried to add the Shield of the Silver Dragon to their sheet. After a few tries of varying search terms, it just did not show up in the Add Items section. After a few hours of looking up afterwards, I tried the same with Crusader's Shortsword, Yester Hill Axe, and Gnomengarde Grenade. None of those items appeared when searching for them. The other Magic Items of Unknown Rarity can be added. I own the sourcebooks for each of the magic items I mentioned here, and I enabled all sources for the Character. Here's a link to the character: https://ddb.ac/characters/96445394/DFOyX9

The Shield of the Silver Dragon, Crusader's Shortsword, and Yester Hill Axe are not in any sourcebook, they are in the Curse of Strahd adventure. The Gnomengarde Grenade is in Divine Contention. Do you own those adventures?

As it turns out, I am not. Those were shared with me by a DM and one of my campaigns, and I forgot it wasn't mine. Completely my bad.
