Thaumaturgy
From FFa2Wiki
The character is instructed in the responsibilities of the guild, and the importance of a Mage’s duties. They are trained in discipline and restraint, so that when they face summoned creatures, they will have the proper mind set to resist the tricks and temptations offered to them. When the character is successfully targeted by a Social Attack or by any Power which targets their Resolve, the character can spend 10 Essence to reduce the number of successes the opponent gained by the character’s Spiritual Attribute. Additionally, when performing a summoning, binding, or dismissing, the character adds their Resolve as additional dice for casting the Summons.
