Diablo 4's loot filter can hide your Mythic Seals if you are not careful
A filter that hides every non-Ancestral item could also hide Mythics, so make sure they are covered by a separate rule.
If you are farming endgame in Diablo 4 Season 15, you should double-check your loot filter settings before your next session, especially if you have configured it to hide every non-Ancestral item. Depending on how your rules are set up, you could accidentally hide Mythic Uniques, especially Mythic Seals, along with the rest of your unwanted loot.
Make Sure Mythic Uniques Have Their Own Show Rule
At some point, when your build is almost perfect, you are high Paragon level, and all you are missing are a few Greater Affix upgrades or some valuable Mythic Seals, you might have set your Loot Filter to hide everything else.
The issue is easy to overlook if you hide all non-Ancestral items to only see Ancestrals and Greater Affixes. Mythics do not necessarily drop as Ancestral items, so a large rule hiding everything that is not Ancestral could hide them, too. And especially when it comes to Seals! Because these rarely drop as Ancestrals.
To avoid missing a potentially valuable drop, make sure you have a separate Show Mythic Uniques rule that takes priority over your general non-Ancestral filter. It is a small setting worth checking before you spend hours farming for Mythic Seals.
After all, the last thing you want is to finally get the drop you have been looking for, only for your own loot filter to make it disappear from view. Luckily, you should still see it on the mini-map, but it is best to set your filter directly.
