Question about attacks?

[sflame56]

So I was wondering if you got multiattack from say paladin and then went into warlock and got the eldritch invocation that gives you an extra attack, do they stack? I was wondering since it doesnt specify if it's considered multiattack or just allows for another attack. Does this mean with these two you can get off 3 hits? One normal attack, eldritch attack, multiattack?

It's Extra Attack, not Multiattack. And no, they don't stack.
