Magic energy

Magic Energy was used by Kain in Blood Omen. It was represented by Kain's 'Magic Meter' - a set of rune symbols that filled with glowing blue energy as Kain's magic energy increased.

Kain's Magic Energy was drained by the usage of Spells, Forms and certain Weapons , such as The Soul Reaver. Kain's Magic Meter would automatically refill if unused. It could however, be manually refilled by drinking Blue Blood (that of Ghosts ) or by collecting Magic Orbs. He could also increase his Magic capacity by collecting Rune Pyramids.
