- "Dumbledore flicked his own wand: the force of the spell that emanated from it was such that Harry, though shielded by his golden guard, felt his hair stand on end as it passed and this time Voldemort was forced to conjure a shining silver shield out of thin air to deflect it. This spell, whatever it was, caused no visible damage to the shield, though a deep, going-like note reverberated from it-an oddly chilling sound."
- —Description of the spell[src]
This spell was told to be very very powerful since when Dumbledore cast it, Voldemort couldn't bear the power of it so he conjured a silver shield to deflect it. When the spell hit the shield, 'a deep, gong-like note reverberated from it-an oddly chilling sound'. Although the spell is powerful, it didn't cause any visible damage to the shield, proving that the shield's power is at least equal to that of Dumbledore's spell. Apparently, this spell is not fatal, as after it was cast Voldemort taunted Dumbledore over his apparent reluctance to kill him.
Another possible explanation was that this spell was an ordinary, unknown spell whose power was amplified with the Elder Wand.
