Prerequisites: Strength of 17
In place of an attack, you can expend a Maneuver Die to strike a creation of magical force, such as a prismatic wall, resilient sphere, or forcecage with a melee weapon. Magical creations from a spell slot of 3rd level or lower are instantly destroyed.
If it was created by a spell slot of 4th level or higher, make a Strength check. The DC equals 10 + the level of the spell slot. On a success, the magical creation is instantly destroyed.
