As Ambitionist said his piece, a pentagonal light zone appeared on the surface of the Leaf of Terror and it perfectly surrounded the Silkworm Mother within it. At that moment, the Silkworm Mother's powerful charge was halted. She was fixed on the edge of the light zone and found it impossible to move. Just from the effect alone, Ambitionist's skill was incredibly powerful but it was practically impossible to put it into practice… the main difficulty was that one had to 'lay down various magical artefacts in the position as pictured below first' (The picture in question was a rather complicated magical zone). After Seal of Soul Imprisonment was inputted into the skill tab, the player would be able to see this picture within the window of skill details).
