Invincible (XC1)

Invincible is an enemy in Xenoblade Chronicles. Invincible enemies dodge all physical attacks and resist all ether attacks, rendering them impervious to anything the player can do.

The only thing that can be done to deal with an invincible enemy, aside from waiting out the aura's duration, is to them to cancel it. Obviously this can be a bit of a challenge given they are immune to any normal means of applying daze.
