Multiattack and reaction

[K1]

Hi there,

If a creatur, let's say a dragon, spend 2 actions to do a 3 attacks action and after the first hit gets knocked dow by a reaction with hammer/fail critical hit + critical specialization, what happens to the rest of his action?

Will he still be able to hit while lying down?

Will the rest of the attack cease?

Anything else?

Being prone still allows it to attack, although with a -2 penalty. So it could continue with the attack routine.

Ok thanks!
