Castlevania: Order of Ecclesia/Glyphs

Glyph Unions
Any combination of the same weapon or elemental type of a glyph works in a glyph union. For example, Confodere + Vol Confodere counts as a Rapier + Rapier glyph union.

Familiars
The Fidelis back glyphs summon familiars that follow Shanoa and attack enemies. Familiars start at level 1 and can reach a max level of 3. They gain experience from hitting enemies and when their Fidelis glyph is absorbed. The fastest method to level up a familiar is to repeatedly absorb their glyph. A passive way to level up a familiar is to go to the room in the Monastery that continuously spawns Zombies, stand on the floating platform, and let it attack the Zombies.
