Dino's perfectly right. Also, Mizuken said it is impossible to conjure indestructible objects; though he has been proven partially wrong, what he probably meant and what the series seems to imply is that you cannot create an indestructible weapon, but other things that are not used in battle as they give you no advantage (Cheetu's hourglass is useless, as it only marks the passage of time; the fact that the marbles in my ability are indestructible actually works against the user, as they cannot squash the enemy after imprisoning them).

Still, if you conjure the armour and strengthen it with Enhancement, it will be a pretty invincible defense. Uvogin's skin is harder than steel, and that's just flesh; think what you could do by combining a natural armour with a Nen defense.
