Dual Wielder Says:

You can draw or stow two one-handed weapons when you would normally be able to draw or stow only one.

Use an Object Says:

You normally interact with an object while doing something else, such as when you draw a sword as part of an attack.

Can my lv 6 Bladesong Wizard use two weapon fighting, and Dual Wielder to do the following:

  • Take the attack action (using Extra attack), to attack with a Rapier.
  • Sheath the weapon as part of the Dual Wielder feat.
  • Cast a cantrip with a somatic component with his free hand.
  • Use a bonus action to attack with his whip.
  • Draw his rapier as the second part of the dual wielder feat.

RAW will this combat sequence work?

Best Answer

Yes

At least by the rules.

The rules for manipulating objects come under:

Other Activity on Your Turn

Your turn can include a variety of flourishes that require neither your action nor your move.

You can communicate however you are able, through brief utterances and gestures, as you take your turn.

You can also interact with one object or feature of the environment for free, during either your move or your action. For example, you could open a door during your move as you stride toward a foe, or you could draw your weapon as part of the same action you use to attack.

If you want to interact with a second object, you need to use your action. Some magic items and other special objects always require an action to use, as stated in their descriptions.

The rules for interacting with objects are limited to one object without using your action. As you are drawing and sheathing the same sword, the rules as written do not prevent you from doing it.

The fact that you are sheathing the sword at a different time than drawing it are not covered by the D&D rules as being important.

There is no second object here. The object interaction rules talk about how many objects you can interact with, not when you can interact with the object (other than restricting it to be during your action or move).

However

It is a common interpretation that the "one object" restriction actually means "one object interaction", not "you can interact with one object".

This is such a common interpretation, you are going to have people say it to you as gospel.

This relies on reading "interact" as a description of a singular discrete event, not as a description of your relationship with the object during the action or move.

So you should talk to your DM.
