Lullaby damage affected by Enemy Def/Prot?

I didn't get to test it a lot so it might be inaccurate because I kept dying, but by comparing the armadillos outside of Filia to the golems on Ceo island, I concluded no change in damage (123 for normal performances, 135 for excellent performances for me at rank A). Also, by testing on the zombies in Their Method Basic, rock throwing only did 1 damage, then I tried lightning bolt and it was still 1, so the extra damage is ignored by level 3 passive defense (not sure about lvl 1 and 2)

oh, and the damage is exactly the same for every normal performances, the same for excellent performances, and the same for inspiring performances.
