MP Cost Rate Down

MP Cost Rate Down is a Main Equipment Perk in Castlevania: Grimoire of Souls that lowers Sub weapon MP cost by 20% when that equipment is equipped as the main Weapon or Armor and in some cases other conditions are also met. This perk cannot be stacked with other perks that reduce this cost - only the perk that reduces it by the most takes effect.
