Trial of the Tranquil Will

Strategy

 * It is more effective to complete both Rain and Fina's trials before completing this one as obtaining all of their equipment will aid with this trial.
 * Frigid Swordsman will barrage one target with melee at around 30% health remaining.
 * Frigid Swordsman will buff himself with Atk, Def, Spr & Mag on the second turn and every turn after (except at around 30%) make sure you have a way to dispel.
 * Having Sakura in your party helps considerably if you have awakened her Defensive Barrier. Defensive Barrier +1 gives 20% damage reduction as well as 40% def/spr boost for three turns. Defensive Barrier +2 does all that for 5 turns. After the initial use she can dual cast Thundaja for its stacking effects.
