D&D 5E Can a hasted bladesinger cast a cantrip with the haste extra action

[ECMO3]

I know haste can normally only be used for the attack action "one weapon attack only" but when a bladesinger 6th level or higher "..... whenever you take the Attack action on your turn ... you can cast one of your cantrips in place of one of those attacks."

So can she take the haste weapon attack and then promptly cast a cantrip "in place of" the attack?

 

[ph0rk]

"That action can be used only to take the Attack (one weapon attack only)"

I'd say no.

 

[TheSword]

Yeah I’d say no. It’s pretty clear that it’s a single attack, not the full attack action.

 

[cbwjm]

I'd say yes. It's still an attack action, doesn't really matter that it limits you to a single attack it would combine with the bladesingers additional extra attack ability to replace an attack with a cantrip.

 

[Shiroiken]

RAW and RAI say no. However, I don't think it's too much imbalance for RAF. If you normally run fast and loose with details, go for it.

 

[Flamestrike]

I also go with - No.

The Haste limitation on the Attack action ('one weapon attack only') overrides the Bladesinger ability to spam a cantrip in place of an attack with the Attack action, because the Bladesinger ability relies on you using Extra attack as part of that action (which the Haste extra Attack action precludes you from doing).

 

[Sorcerers Apprentice]

No. The "one weapon attack only" restriction clearly means that the attack action from haste can only be used for making a single weapon attack and not anything else you could otherwise do with an attack action.

 

[Nefermandias]

The RAW is no.
That said, I do have an issue with the fact that this isn't nearly as clear as it should be, like many other things in 5e.
Natural language, man.

Natural language, man.

Natural language reduces precision, unfortunately.

Look up one of the many "can devil's sight see through hunger of hadar/shadows of moil" discussions out there, as only one example.

Yes.
God forbid using icons, keywords and color code to present game mechanics. People might think we have something to do with 4e.
