How useful is Depth Galea in Grave Danger Quest?

Question

Players always ask to get the Depth Galea item in the Grave Danger Quest, my question is to know the usefulness of this item during the Quest.

Answer 1

Depth Galea in Grave Danger Quest is useful only in one moment, during a fight with The Red Knight - one of mini-bosses that you must kill before fight with King Zelos.

When you kill Vampiric Blood it will explode dealing drown damage to the boss... and to the player.
