Character Story

Champion of Torta, and daughter of the Grand Warrior Magna. Osla Magnatira was strong from birth. She vowed to the sovereign of Torta that she would never be with a man unless he was stronger than herself. In her 26 years of life, she had yet to meet a single man stronger than her, other than her father.

Though she held no belief in the sovereign of Torta, she felt that breaking her vow as a Magnatira would be a stain upon the name of her father. So, even in her moments of regret, she waited for a groom stronger than her to appear. After escaping the Rift under Maximilia's command, she began a new life on Earth.

She hoped that here she would find her match, and upon hearing her story, the Bureau of Rift Management told her about the power of the Human Sovereigns. Hearing this, she decided to wait within the bureau as a reserve Vanguard, hoping for a Human Sovereign worthy of taking her hand.

EX 5

During battle, movement speed increases by 32% and Aggro Adjustment increases by 40. For any enemy that initiates an attack on the unit, all support counterattacks, counterattacks, or additional attacks directed at that enemy during the same turn are treated as Weak Point Attacks (provided the skill used is eligible for Weak Point Attacks). When attacked, allied units - except the unit under attack - receive the [Primordial Spirit's Descent] effect. This effect can stack up to 5 times. -[Primordial Spirit's Descent]: On a successful attack, inflict additional Slash DMG and remove 1 stack from the effect. Additional DMG equals 320% of the Melee ATK power of the effect provider, with damage increased proportionally to CRIT rate (damage doubles at 100% CRIT rate). This effect activates only via a single weapon during battle; if the weapon-bearer becomes incapacitated, the effect ceases.

Signature Skill: Ancient Spirit's Core

Signature

During battle, the probability of applying the [Taunt] effect from the 'Afflict Pain' skill increases by an additional 43%. In addition, if the current HP of the unit falls below 30% upon receiving an attack, restore 10% of maximum HP. The additional Slash Damage from [Primordial Spirit's Descent] is applied at double strength.

Requires Osla: only takes effect while Osla has this weapon equipped. Fixed: no weapon level or EX scaling.

Note: This signature skill only activates when Osla equips this weapon.
