Piercing Beam

Piercing Beam is is the signature attack of the Nova Skeleton. A medium-width beam of energy is emitted from its body. The beam attack has long, but limited range.

The attack can be obtained by Soma Cruz by capturing the Nova Skeleton's soul in Castlevania: Aria of Sorrow and Castlevania: Harmony of Despair. Shanoa is able to absorb its related glyph (called Nitesco) from it in Castlevania: Order of Ecclesia and Castlevania: Harmony of Despair. Charlotte is able to use it as a spell in Castlevania: Portrait of Ruin (where it has unlimited range) and by capturing it from the Nova Skeleton in Harmony of Despair.

Castlevania: Order of Ecclesia
The Nitesco glyph is both a fire and a light spell. An exceptionally large version of the Nitesco beam is emitted as a Glyph Union between two Nitescos. In Latin Nitesco means "to begin to shine, grow sleek"
