If you mean rare loot, there's a way to get rid of it:
1. Click right mouse button on "discard" on any item and choose "Copy link" or something like it. Link's gonna look like this: https://www.lordswm.com/inventory.php?sell=[ItemID]&sign=[Code]
2. Click right mouse button on the name of item you can't discard and also choose "Copy link". It's gonna look like this: https://www.lordswm.com/art_info.php?id=mage_boots&uid=[ItemID]
3. Swap ItemID in the first link with ItemID from the second link and use it.
