Sadeena/Powers and Abilities

Natural and Learnt Abilities
Sadeena can fight both in close quarters combat and with magic. She can also use a wide range of ritual magic, including self-buffing magic as well as Ceremonial Magic and Way of the Dragon Vein magic, even being able to swiftly counter-cast Zweite-level spells. She's also a very skilled fighter, being able to more than hold her own against Naofumi, Raphtalia, and Filo while untransformed, even going as far as pointing out their mistakes while fighting. They could have beaten her had they not been cursed at that time, though. Just like whales, killer whales, and dolphins, Sadeena can use sonar to locate objects and people. This also can render illusion magic ineffective. Sadeena can transform into a form resembling a humanoid killer whale on land, with legs and arms, unlike a normal killer whale. This form increases all of her stats and raises her fighting ability while in water environments even further.
 * Echolocation
 * Therianthrope Form

After achieving level 100, Gaelion conducted the level-100 limit breaking ceremony on Sadeena. She chose to specialize in agility, strength and then magic compared to her relatively balanced stats before. After the ceremony, her stats were almost double what they were previously.
 * Class-up

As a previous Water Dragon Miko Priestess, Sadeena received additional training to understand the essence of souls. Over time, both Sadeena and Shildina started to recognize a common factor behind reincarnated individuals like the Vanguards of the Waves and eventually became able to easily point them out.
 * Reincarnation Recognition

Magic
Sadeena is extremely proficient magic and often combines it with her physical abilities in combat to great effect. She is naturally gifted with lightning magic affinity which is very rare for killer whale therianthropes although she can also use water magic. She is also well-versed in Way of the Dragon Vein which allows her to cast magic from the surrounding elements and counter other spells. Sadeena is able to use up to Drifa-level magic which is the highest level available to non-heroes and can also use cooperative magic.

Ritual Magic
Several blindingly bright bolts of lightning shoot out from Sadeena towards her targets. This lightning magic then jumps from target to target, causing electric damage. Sadeena often favors channeling this spell out of her harpoon. A counter-spell that nullifies the effects of the Aura spell before they're applied. An ultra-thick bolt of lightning. Naofumi notes that such power puts it on par with the ritual magic Judgement. Lightning rains down on Sadeena, enveloping and electrifying her body, raising agility. This also electrocutes nearby enemies, like static electricity. This spell envelops Sadeena in thunder, protecting her from attacks. This spell shoots a bolt of lightning. The electricity can be redirected if it strikes a conductive object, such as iron. It is electric-type paralysis magic.

Techniques
Sadeena throws her lightning charged harpoon and then uses the electromagnetic properties of lightning magic to remotely control it. This technique surrounds Sadeena with water in the shape of a Chinese dragon as she attacks the target. Sadeena focuses swirling water around her tail which she then uses to strike the target.

 * Unnamed Wind Infused Charge + Wind Bullet Filo

This techniques accomplished through the cooperation of Filo and Sadeena where Filo (in an eagle-like form) envelopes herself in wind, transforming into a bullet of wind while Sadeena infuses her harpoon with that same wind and uses Dragon Vein Magic using a jewel. They both then charge towards the target with Filo having a high enough maneuverability to even do a 180°. Sadeena herself mentioned that this technique is a copy of the Harpoon Reincarnator's Lightning Strike Dragon.

Dragon Vein
This spell utilizes Way of the Dragon Vein and holy water to summon a glowing mass of water to crash into its target. This spell utilizes Way of the Dragon Vein and holy water to reduce the amount of damage from fire and cursed attacks. This spell makes magic with wind resistance appear in front of Sadeena.

Cooperation Magic
Sadeena casts this magic in cooperation with Naofumi and is a combination of her lightning magic and the hero-exclusive Aura magic. This buff makes the target's stats skyrocket and allow them to use Electric-type attacks and combo skills. After Naofumi learned to use Liberation-class magic, they were able to cast Descent of the Thunder God at that level.

 * Zee Wille「ゼー・ヴィレ Zee Vire (lit. See Viele, "Great Lake/Sea" in Broken German」

This spell was cast with the cooperation of Sadeena (The Great Deep), Wyndia, and Melty (Zee Wille). It summons a massive body of water around the users casting it like a huge aquarium. Fortunately, it only affects those the users consider an enemy so allies will not drown in the water.

This spell was cast with the cooperation of Sadeena, Gaelion (Annihilating Wave of the Water Dragon), Wyndia, and Melty (Erasing Aqua Slash). With the magic, Gaelion summons a dense ball of water. As he infuses his breath attack into the ball a massive torrent of water erupts from the other side towards the target. Sadeena then leaps into the raging torrent, swims in circles until it becomes a vortex flying towards the target with Sadeena inside. The magic Annihilating Wave of the Water Dragon, that was translated as Water Dragon Destruction, was noted by Naofumi to be visually similar to Shildina's Wind God Armor.
 * Erasing Aqua Slash「イレイズアクアスラッシュ Ireizu Akua Surasshu」
 * Annihilating Wave of the Water Dragon「水龍滅波 Suiryuu Metsu Ha (lit. Water Dragon's Wave of Annihilation)」

Sadeena then jumps into the tornado and the two turn into the form of the Water Dragon and slam into the target.

 * Gale and Thunder Gods「風雷神 Fuuraijin (lit. God of Wind and Thunder)」

A cooperation magic involving Sadeena and Shildina's lightning and wind magic to create a thick blast of lightning which combines with an air-shredding tornado. Naofumi notes this spell to be more powerful than The Church of the Three Heroes ceremonial magic - Judgement.

Jewel Magic
While in Glass' World, Sadeena is able to use Jewel Magic with Way of the Dragon Vein, however this puts strain on the jewels and cannot be used too often.

 * Jewel Aqua Blast「ジュエル・アクアブラスト Jueru Akua Burasuto」
 * Jewel Spark「ジュエル・スパーク Jueru Supaaku」

Demon Dragon Magic
While in Glass' World, the Demon Dragon Emperor unsealed this magic for non-monsters. This allowed Sadeena to create a temporary contract with the Demon Dragon which to empower her spells using the Demon Dragon's power.

Summons a cursed cross which sucks the target onto its surface. While the target is held by this skill, they are both restrained and burned by the cursed cross at the same time. Mistranslation of Sadeena using said magic instead of the Demon Dragon.
 *  Binding Cross 

Beast Transformation
With the help of Naofumi's Beast Transformation Assist skill from the Shield of the Beast King, Sadeena is able to transform into a massive killer whale form which is much more powerful than her regular therianthrope form. Both her physical and magical abilities are boosted and with this form she can now swim in air as though it were water.


 * Thunder God「鳴神 Narukami (lit. Thunder God)」

This spell summons thunderclouds above the target and drops a thunder-strike larger than any of her usual spells. Sadeena does eventually learn to perform the spell, albeit a slightly weakened version, without undergoing a Beast Transformation.

Vassal Harpoon
After liberating the Vassal Harpoon from a Vanguard of the Wave, the Vassal Weapon chose her as its new worthy owner. Due to her extensive training and combat prowess in using a harpoon, she is able to use this weapon incredibly effectively. In addition, the Vassal Harpoon's power-up methods allow her to upgrade her stats beyond what any non-hero can achieve.
