Red Orbs
From God of War Wiki
Red Orbs are a type of orb in the God of War series. They are the most common type of orb, and they're used to level up Kratos' weapons and magic powers. Kratos can get them by defeating enemies (he'll get even more if he performs a special kill on them); by smashing just about anything around him with his blades; opening up Red Orb Chests; and racking up Combos.
