Doing X and/or Y, at least once, will reduce the boss' armor.

Doing X and Y multiple times to reduce the boss' armor is more noticeable on higher difficulties.

On easy, doing X and Y at least once seems to be effective enough, but three times seems to be the most common number.

Just remember that you have to sink the flagship, i.e. the Installation boss, to get the debuff to work.
