Can a multiclass Eldritch Knight/Mage of Lorehold Wizard benefit from War Magic and Lessons of the past at the same time?

Question

I was considering a multiclass Eldritch Knight/Mage of Lorehold Wizard.

The Eldritch Knight feature War Magic states

when you use your action to cast a cantrip, you can make one weapon attack as a bonus action.

And Mage of Lorehold Wizard's Lesson of the past-Warrior says

If you use your action to cast a cantrip, you can make one weapon attack as part of that action.

My question is, as both classes use the Wizard spell list, and both classes can cast the same cantrip, can I benefit from both at once? As one is a part of that action and the other is a bonus action? So cast a cantrip, melee attack as part of that action, then melee again as a bonus action. Or is it one or the other?

Answer 1

You can make two attacks

The two abilities aren't at odds because only one uses a limited resource (a bonus action which you have only one per turn). Even if you made a weapon attack *as part of the Action" you used your action to cast the cantrip and so can use your bonus action for another attack.

The spell list or the specific cantrip cast are unimportant so long as an Action is used since both features simply require a cantrip be cast as Action.

Of course these two attacks are in addition to any attacks the cantrip lets you make. Those can even be a weapon attack as well in case of Booming Blade or Green Flame Blade.
