Elemental Power

Elemental Power, often just called power, is a battle statistic that determines how much damage an Adept will do with element-based attacks such as Summon sequences and weapon unleashes. An Adept will have the most power with their innate(base) element, and lesser power with the other elements, especially with the polar opposite of their base. An Adept with no Djinn set and no power-increasing items equipped will have 104 power in their innate element, 78 power in their neutral element (Mercury-Venus and Jupiter-Mars), 77 power in their opposed element (Mercury-Mars and Jupiter-Venus), and 76 power in their symbiotic element (Mercury-Jupiter and Venus-Mars). It should also be noted that the maximum Power or Resistance of an element is 200.

Temporary increases
Such increases are generally in the same element as the djinn required for the summon, with greater increases correlating to greater numbers of djinn.
 * Using a Summon will increase that character's Elemental Power.

Permanent increases

 * Set a Djinn. It will raise the power of the Adept by 5 in that element, regardless of class.
 * Equip Equipment that increases Elemental Power; a list of items that increase Elemental power can be found here for Mercury, here for Venus, here for Mars, and here for Jupiter.

Ways to decrease Elemental Power
There are no known ways to decrease Elemental Power, however it should be noted that the Break Psynergy will eliminate all bonuses any affected Adepts have received from Summoning or any stat-boosting Psynergy/Djinn in battle.
