@JeremyECrawford Can a character move into a space occupied by their ally, make an attack from that space, and then move away?

You can't willingly stop moving in another creature's space. #DnD https://t.co/JojMKXpXbT

@JeremyECrawford @BobbyBarbarian Is it 'can't stop moving' or 'can't end your turn in a square'?

@aus_maverick @BobbyBarbarian Move, not turn. See the Player's Handbook, p. 191.

that's still very much unclear. Can you move (squeeze) in ally square attack (with DISADV) then move out? yes/no?

"Whether a creature is a friend or an enemy, you can't willingly end your move in its space"RAW about squeezing does not specify anything like that, make an errata or this is RAI (for which Mearls gave a different interpretation) (PH, 191).

We are indeed not talking about ending the movement. Point is whether you can squeeze into an ally square to attack (with DISADV)I quoted the relevant rule, and I tweeted the intent last year. If you'd like the rule to work differently, I encourage you to house rule it
