@JeremyECrawford how much cover is needed to make a hide roll in combat? As a general rule.

The DM determines whether a creature is sufficiently obscured to successfully hide. And even if there is enough concealment, the DM might decide your attempts fail if you, for example, keep hiding behind the same pillar and your enemy watches you do it. #DnD https://t.co/LRokTZimzu
