Well it isn't 100% guaranteed since this buff only has 70% chance to apply, but it is reasonable. ATK down can reduce the majority of the enemy's damage unless it is fixed damage. Especially since this one is 50% ATK down, it's really similar to mitigation. If one applies this debuff onto the enemy and mitigates on the same turn, it's really close to reducing the damage you receive to 75% (unless you receive fixed damage of course).

However, if you haven't used Haile or Zedus yet, then try them out now. Their SBB can also apply the 50% ATK down with a 50% proc rate. If you go into raids for example, you can see that this debuff can still apply a lot of times. How can the 70% proc rate not occur more often? That is unless RNG isn't in your favor.
