Brundia's Sanctuary (Valkyrie) skill

With the consecrated sword held upright, a quiet prayer is offered at the heart of the battlefield. As the prayer deepens, divine energy seeps into the ground. Light radiating from the sword's tip spreads to form a sacred zone. Answering the heartfelt prayer reaching the heavens, a radiant beam of light strikes the sword, transforming the battlefield into a sanctuary imbued with the will of the divine. The exploding divine power inflicts Atk. Power Damage to nearby foes, and blows them away with Powerful Shock. Piety Meter +60%. Grants a shield equal to 100% of your Max HP for party members within 24 meters for 10s. If fatal damage is taken within the next 30s, grants Invincible for 3s.
