Also know as MP, Magic Points are one of the most important stats found in the Shadow Hearts series. These are measures of how many abilities a character can cast. Every time a character uses an ability, an MP cost is deducted from their Maximum MP value. When a character runs out of MP, they will not be able to use any more abilities, and will have to resort to their weapon or some other form of attack. Various items and resting with a Tent or at an Inn usually restores MP. Naturally, stronger abilities tend to have higher MP costs.
Various abilities and equipment can alter how MP is consumed. The Priest Earrings, for example, reduces MP costs for abilities by 20%. Also the notable abilities of Lucia's Aromatherapy, Tarot Cards and Ricardo's Serenata can effect a character's MP cost and values.
