How to Import a Loot Filter in Diablo 4
Follow a conservative setup flow: review the preset, import only verified codes, and check rule priority before serious farming.
Paste only verified codes
If a preset includes a code, confirm it is marked for the current season and patch. If not, use the manual show, hide, and recolor rule list.
Test before farming
Run a low-risk activity first. Make sure valuable drops are not hidden before using the filter in Hardcore, boss farming, or high-value routes.
