@JeremyECrawford Mummy Lord: Lair Action says it can activate "pinpoint" accuracy for the undead to locate creatures. Disadvantage is applied when you cannot "see" your target. The Lair Action says nothing about removing Disadvantage. Pinpoint isn't a game term. Disadvantaged?

The mummy lord has a lair action that can pinpoint creatures in its lair. The action does exactly that: pinpoints the creatures, which makes it difficult to sneak around in a mummy lord's lair. The action doesn't make the invisible visible, but it pinpoints the invisible. #DnD https://t.co/8tudGnf4aJ
