Flurry of Blows vs multiple attackers

Is there anything that restricts you from continuing your FoB's attacks on another creature after you have killed your opponent?

For example Your last attack, one of your two FoB's just killed your opponent and you want to go help your buddy 10 feet away. Can you move there and attack his opponent with that final FoB or are they supposed to be used all at the same time on one creature. 

Thanks

While the rules don't permit moving during a bonus action, Flurry of Blows is, AFAIK, the only situation where moving between attacks is even possible during your BA, and I don't think it's unreasonable to allow it.

I would take the opposite approach and rule that one can't move between the strikes of a use of Flurry of Blows. The ability doesn't allow you to strike, move, then strike again - it allows you to make 2 (or more) rapid strikes in quick succession (but they can be against different targets). Also the rules on movement while attacking clearly state that movement during a bonus action attack is not allowed.

Well, sort of. The rules on moving during a combat only don't say it is allowed. Just like they don't say it's allowed during an action. The attack action says it's allowed.

Now, while FoB doesn't say it's allowed (so it is, by default, not), Monk is a class whose schtick includes:

• A lot of mobility
• A lot of attacks

So there's a reasonable argument to be made in favor of house-ruling it. (Also, I'm pretty sure most people who aren't paying careful attention won't even notice they're house-ruling it. It just feels more natural.)

Mostly what I do as a player is take my FoB first, then move during the attack. It's rare that you want to spread your attacks all over the world, so it works. Even when I'm doing the elements monk thing of punch-knockback-punch-knockback-etc., moving to keep up with the dude I'm yeeting, misses, saves, and range mean I'm unlikely to actually need to move mid-flurry.

While RAW you can't move between attacks during a Bonus Action,  RAF if someone should be able to among every classes it's the Monk as a very mobile character with multi-attack BA capability.

As noted above, you're only able to move in the time between Action and Bonus Action, not during them. There is an exception to this: if you have the Extra Attack feature, you can move between attacks during the Attack Action.

There is no such exception for the Bonus Action or other activities that might occur during the Bonus Action.

 You are of course free to rule however you wish at your table, but the Flurry of Blows is not just getting an extra attack, it is attacking so rapidly that you get to do two (or more) in the time it takes others to do one. It is actually the flavor of monks to NOT be able to move between those flurried attacks. Monks get faster movement and can use that faster movement anywhere in their turn that they wish to give themselves that 'very mobile' flavor - but the one spot they can't do it, is in between flurried attacks.

The rules is not for or against Monk's Flurry of Blows or Faster Movements, RAW no one can move between attacks made as Bonus Action or Reaction.

I just think its more fun if they can.
