; Limiting by mod is a bit tricky at the time of writing. If a filter has only mod name, it will work as expected only when the mod is active. If the mod is not enabled, the keyword will be assigned to ALL items. To work around it, add at least one existing Editor ID, the rule will be skipped correctly. I am using an unused keyword TGMark, keyword IDs are loaded by default without the need for powerofthree's Tweaks.

Keyword = ETR_ExtraArtifact|Book|TreasureHunter.esp,TGMark,-0x1E55~TreasureHunter.esp,-0x67BC~TreasureHunter.esp,-0x787C~TreasureHunter.esp,-0xB0E2~TreasureHunter.esp,-0xB0E4~TreasureHunter.esp,-0x1F04B~TreasureHunter.esp

Keyword = ETR_ExtraArtifact|Book|treasure_hunt.esp,TGMark,-0x80A~treasure_hunt.esp

Keyword = ETR_ExtraArtifact|Potion|yumcheese.esp,TGMark

; Include seashells. They have VendorItemClutter, which is skipped via the ETR_ExcludeMiscKeywords formlist, we need to include them explicitly
Keyword = ETR_ExtraArtifact|Misc Item|Seashells.esp,TGMark

; Exclude pouches with WACCF keywords
Keyword = ETR_NotArtifact|Armor|WAF_ClothingAccessories,-ClothingHead
Keyword = ETR_NotArtifact|Armor|WAF_ClothingPouch
