# Can I spend additional ki points to make additional attacks with my Flurry of Blows bonus action?

I just re-read the rules about monks and I wonder how to interpret this from the PHB:

Immediately after you take the Attack action on your turn, you can spend 1 ki point to make two unarmed strikes as a bonus action.

Can you spend additional ki points to make additional attacks as part of the Flurry of Blows bonus action, e.g. 2 ki points to make four attacks with your bonus action?

• I’ve clarified your question based on your comments so that it is not a duplicate. You’ve indicated that you’re not asking about additional bonus actions, rather asking if you can spend additional points for additional attacks as part of the same bonus action, is this correct?

• Yes! To be honest, that question was not my first idea, but it developed during writing the question. Probably because of that the question was not precisely enough written. Ty for clarifying that :-) Commented Nov 28, 2023 at 8:04

## You can make one flurry with two strikes

Flurry of Blows is not limited by a number per turn, but by coupling it to taking the Attack action on your turn, and by your available bonus actions:

Immediately after you take the Attack action on your turn, you can spend 1 ki point to make two unarmed strikes as a bonus action.

So, if for example you have a multiclass fighter/monk who has Action Surge, they can use it to take a second Attack action in the same turn. However, since Flurry of Blows is a bonus action, you still cannot make multiple Flurry of Blows, because you normally only have one bonus action per turn, and Action Surge only gives you an additional action, not also an additional bonus action. p. 189 PHB:

You can take only one bonus action on your turn, so you must choose which bonus action to use when you have more than one available

It also only allows you to spend one ki to make two unarmed strikes as a bonus action. There is nothing in there that says you can spend 2 ki to make four attacks as a bonus action, or 3 ki to make six attacks. It would need to say something like "For every ki point you spend, you can make to additional attacks; all these attacks are made as your bonus action". It does not say anything like that.

• Actually, I was wondering if spending two ki points would give a bonus action consisting of four attacks ... Commented Nov 27, 2023 at 14:34
• No, you spend 1 ki to "make tow unarmed strikes as a bonus action", not "to make 2 unarmed strikes per ki point spend as a bonus action". Commented Nov 27, 2023 at 14:34
• Minor nitpick - it is unclear if you can spend 2 ki points to get 2 × (two attacks as a bonus action). Currently it is purely theoretical because there are no sources of additional bonus actions per turn in the game (that I know of) so getting ability to use that nonexistent second bonus action for anything is meaningless, but it may matter in the future for character optimization etc. Commented Nov 28, 2023 at 7:43

## You only have one bonus action per turn

Flurry of Blows uses your bonus action so even if you could take the Attack action twice per turn, you would still only be allowed to use Flurry of Blows once as you only get one bonus action per turn and as far as I know there are no means to get more of them.

Regarding your second question, the wording to me implies that "immediately after you take Attack action is meant to apply to both spending the ki point and making the unarmed strikes so strictly reading the rules no movement would be possible, you're spending the point and making the strikes at the same time, there's no interval between them:

Immediately after you take the Attack action on your turn, you can spend 1 ki point to make two unarmed strikes as a bonus action.

I tend to not be very strict though so if a player asked this at my table I would allow them to move in between but wouldn't allow to do anything else.

• OP clarified the meaning of their question, so your answer doesn’t really address the question anymore. Commented Nov 27, 2023 at 22:41
