[RPG] If I have the fighter’s Extra Attack feature and the warlock’s Thirsting Blade eldritch invocation, how many attacks can I make

I am playing a half-orc fighter level 7 and warlock level 3. When I gain a warlock class level, I will gain an Eldritch Invocation, and I will pick Thirsting Blade.

How many attacks can I make, since I have both Thirsting Blade and Extra Attack?

Best Answer

Thirsting Blade does nothing if you have Extra Attack from another class.

The rules for multiclassing (chapter 6 of the Player's Handbook) state:

the warlock's eldritch invocation Thirsting Blade doesn't give you additional attacks if you also have Extra Attack.

So the Thirsting Blade invocation does nothing for you. So you get to pick a different invocation!
