You attempt to interrupt a creature in the process of initiating a form or casting a spell. If the creature is initiating a form or spell of 3rd level or lower, the ability fails and has no effect. If it is initiating a form or casting a spell of 4th level or higher, make an ability check using your ki ability. The DC equals 10 + the form or spell's level. On a success, the creature's action fails and has no effect.
At Higher Levels. When you initiate this form at a higher level, the interrupted form or spell has no effect if its level is less than or equal to the level of the form you used.
