Units in battle areas are split between the player, allied allied characters or the level's enemy force. There are six commands available: Move, Attack, Defend, Heal, Patrol and Gather. Units are summoned from runes conjured by magical books called Grimoires.
Runes can established on each floor of the level, with each three of the twelve available runes aligned to a different form of magic. Establishing runes and summoning Familiars require Mana, magical energy gathered from crystals on some floors using units from the Glamour class. Grimoires can be levelled up, granting access to new and more powerful units.
