Bang!
At the very instant the claw made out of swords had touched the pillars, due to the great amount of power imbued in the claw, the pillars' defense was more or less akin to paper as their pillar shape had been destroyed. What remained after the collision between claw and pillar were only remnants of energy that could be attributed to the 'strong' pillars from before.
Then again, the power imbued in the claw was more than enough to create a shockwave as it collided with the pillars, destroying the pillars in its surroundings through the shockwave it has formed. Surprisingly, the number of pillars destroyed by the shockwave was more than the number of pillars destroyed by the claw directly colliding with them.
