Abyss Shriek

Use
Upgrade to Howling Wraiths.

Press FOCUS/CAST or QUICK CAST while holding UP to release a wave of energy in an arc with increased range around and above The Knight, dealing 4 bursts in quick succession that deal 20 damage each.

It is 16 times stronger than an un-upgraded Nail, making it the second strongest unmodified attack in the game, with the only other contender being the combined seven strikes of Cyclone Slash.

How to Acquire
Stand on the pedestal in the room of the bottom left of the The Abyss and use the Howling Wraiths spell.

Attacking the faces with the Dream Nail will reveal the dialogue "Our voices shall be heard again..."
