Grand Knockdown

[Mokuzzai]

T4 Knockdown upgrade, this is not an original idea, but I would like it anyways

Like knockdown you would target an enemy, and after a short duration they would get stunned and grounded. The stun duration would be improved.

Once the enemy hit the ground, a shockwave would stun all enemies in a radius around the target.

Visually instead of an anvil it would look like a grand piano.

I thought about this item a bit more, and this variation is much stronger, maybe too strong since it no longer counts as a debuff and cannot be debuff removed.
