Question about Multiattack, @JeremyECrawford: If a creature has a Multiattack that includes two attacks A and an attack B, and A has longer reach/range than B, can it use that Multiattack when its target is out of reach/range of attack B, or can it only use attack A once? #DnD Are you asking whether a creature can use its Multiattack even if one or more of the attacks can't occur?

Yes, that’s correct. Or rather, specifically, I’m asking if it can do that if the Multiattack action is worded “Creature does X” and not “Creature can/may do X.” A monster can use its Multiattack even if one or more of its attacks have no chance of hitting.
