A layer is removed immediately after a rune next to the petrified rune is dissolved, and thus before you attack. With a petrified 2-layer rune like in this stage, you can quickly dissolve a set of runes next to the petrified rune, then next run make a normal attack (as long as you make sure a rune next to the petrified rune is dissolved).

As you don't get bonus points if you complete the stage in less than 10 rounds, it may be more efficient to just waste a round here instead of bring a defense breaker.
