Skill 1 has 90% success rate at level 6 if she's equipped with a MLB Self-Geass Scroll. (Level 6 is also the point where it gets cooldown -1). If you want 100% Stun you can get it at level 8 without having to use a Lore.

You can use a non-MLB scroll to boost her stun chance too; there's only a 3% difference between the two.
