Dual Wielder + Extra Attack question
I'm running a 5.5 campaign that just hit level 5 and it's been going really well! But I have a question about the 5.5 Fighter since it's my first time running a game with one.
The fighter took the Dual Wielder Feat, and is using a short-sword + dagger. So far that's played out as using their main Attack to do Sword + Dagger, then their Bonus action to Attack with the Dagger, since it has the Light property.
Now with Level 5 the character has Extra Attack also. I think that, all together, that should bring their total number of attacks per turn up to 4? But I'm not sure. My reasoning goes that Two Light weapons without any feat would let them attack twice- once with their Normal Action, once with their Bonus action. Weapon Mastery (Nick) lets them move those two attacks into their main action and free up their Bonus Action. Dual Wielder Feat lets them then use that Bonus Action to attack again. Extra Attack then should just add one attack to their Main Action making the rhythm Action (Shortsword, Shortsword, Dagger) and Bonus Action (Dagger) but does that hold together, or is it a nerf?
