CON Boost is a stat boost spell or power that increases Constitution.

Game specific information

Castlevania: Aria of Sorrow

In Aria of Sorrow, Soma Cruz is able to obtain this ability by gaining dominance over the souls of four different creatures, thus dividing the CON provided in four levels of power, with a difference of four units between each other:

Castlevania: Dawn of Sorrow / Castlevania: Harmony of Despair

In Dawn of Sorrow and Harmony of Despair, Soma is able to gain this ability from a Bone Pillar's soul, and the more such souls he has, the more powerful the effect.

Castlevania: Portrait of Ruin

CON Boost is one of Charlotte Aulin's magic spell skills in Portrait of Ruin. When cast, it boosts CON temporarily. A regular cast boosts CON +15, while a fully charged cast boosts CON +30.

Jonathan Morris has a counterpart for it, named Defensive Form.

Castlevania: Order of Ecclesia

Fortis Fio is a back glyph that increases Shanoa's constitution. This bonus scales as her CON stat increases, and thus, grows in power as she levels up.

A warning to keep in mind is that Fortis Fio, oddly, overrides the (usually) more powerful CON boost from using a Scutum glyph if both are in effect.
