@JeremyECrawford Movement of Moonbeam not count as creatures entering when spirit guardians moving into creature counts as entering?

Moonbeam, spirit guardians & the like work the same way: a creature, not the spell effect, does the entering. #DnD https://t.co/7bwknIJJId

@crimsonknight52so if pc casts spirguard, and the badbuys are alrdy in zone, or moonbeams right on badguys, no save/dmg until badguys turn? Correct.
