Caster of Okeanos

“I love you so much that I want to turn you into a piglet…...seriously.”

A witch of temptation who seems to be friendly and loving on the outside, Caster of Okeanos is notorious for turning the men abusing the hospitality of her islands into cute tiny piglets. On the battlefield, she is a damage dealer boasting an on-demand instant single target Buster NP, powerful utility through her unique Pigify status, and access to rare teamwide debuff cleansing.

Caster of Okeanos’s general gameplay revolves around her Noble Phantasm Metabole Piglets, a single-target NP which happens to Pigify its target, triggering a special stun effect for 1 turn. Caster of Okeanos is able to create this merry spectacle immediately through Rapid Words of Divine’s on-demand full 100% NP charge, a skill many can only dream of having. Tactically, Caster of Okeanos thus has great freedom regarding Craft Essence choices, which compensates significantly for her lack of steroids. Additionally, she can provide a decent amount of team support as well, either through Navication Advice’s party-wide debuff removal and Stargen buff, or through Poisoned Food’s AoE Defense Down and poison. 

However, the remaining aspects of Caster of Okeanos' kit are less glamorous. In return for the powerful Rapid Words of Divine/Metabole Piglets combo, her normal NP gain is nothing short of horrendous, with the only solace being her triple Arts deck. Furthermore, despite in practice having decent burst damage through powerful Craft Essences, her sustained damage is rather poor, partially because of the aforementioned NP gain, but also due to her lack of powerful steroids as well as the ever-present 0.9x Caster modifier. Finally, she has little to no survival capabilities, save for what damage is prevented through Pigification.

Thus, for Caster of Okeanos there is more than meets the eye at first glance. With the correct CE, NP Upgrades, and supports (i.e. Merlin), her lack of offense for veteran Masters is much less crippling, while the value and freedom brought by her instant NP and utilities become far more prominent.

Besides, the sight of enemies turning into piglets should be more than enough for Masters to perch her presence on the battlefield!

Instant NP and Craft Essence Flexibility

Aside from just providing easy access to her NP, Rapid Words of Divine also allows Caster of Okeanos to be more picky regarding her CEs. This advantage ensures access to her most optimal CE choices, something she desperately needs due to her questionable base damage. A prime example of this is her ability to either equip Event (Damage) CEs without a massive decrease in performance, or equip the monster that is the Black Grail.

Powerful Crowd Control NP

Metabole Piglet’s Pigify effect is effective against normal Servants, who account for most of the in-game boss fights. The capability to perform what is essentially an instant, guaranteed stun (or two of them back-to-back) is a very powerful tool for some difficult quests, especially those requiring the team to stall a high-damaging boss. 

On-Demand Utility and Support

Caster of Okeanos possesses various useful utility and support tools, ranging from her NP’s Pigify, to Navigation Advice’s debuff removal and star generation, to the extra damage provided by Poisoned Food’s Defense Down debuff. She is able to access all of these at a whim, making her a very effective Order Change Servant to negate various gimmicks, boost damage a little or shut down the enemy for a turn or two.

Horrendous Base NP Gain

Despite having the benefit of 3 Arts cards and Territory Creation, Caster of Okeanos’ base NP gain is frankly rather pathetic. This weakness is further exacerbated by her Buster-type NP preventing any NP refunding or improving her NP Gain via an Arts card first bonus. Masters need to rely on Arts chains to (re-)charge her NP.

Low Sustained Damage

With middling attack stats, a small single teamwide Defense Down, and the 0.9x Caster modifier, Caster of Okeanos' NP is her only source of meaningful damage. Sadly, her base NP damage is among the lowest of her rarity if Masters do not compensate her lack of steroids with powerful CEs, and she is also unable to spam it either due to her low NP gain. As such, she falters in stages requiring constant high damage output.

Low Durability

While Metabole Piglets’ crowd control effect provides some semblance of defensive measure, Caster of Okeanos otherwise lacks any other sort of survival-oriented tool, which forces her to rely on external support for survival in more difficult fights. 

Among Caster of Okeanos’ three skills, Rapid Words is by far the most important to level, and it is recommended to raise it to level 5 or 8 (with / without Merlin, respectively) as soon as possible. Her second skill should also be leveled, to maximize the amount of damage she can dish out especially due to how it scales with any CEs. Her third, in contrast, scales poorly with additional levels, and can generally be left at a lower level. 

• Rapid Words of Divine B is the crux of Caster of Okeanos' skill set, and should be raised to at least level 8 from the get go in order to hit 100% NP charge benchmark. The remaining two levels can generally be ignored, though the additional cooldown reduction gained on level 10 may prove useful in more intense fights. Level this first.

• Poisoned Food A reduces the enemies’ defense and poisons them for 3 turns. While the poison is little more than a bonus, the Defense Down brings a reasonable benefit to Caster of Okeanos as well as her allies. This skill should ideally be leveled second after Rapid Words of Divine.

• The main draw of Navigation Advice A is its party-wide debuff removal, the effectiveness of which doesn’t scale with additional levels. Meanwhile, its star generation buff is situational at best and has only minor scaling per level, leaving it as the last priority in terms of leveling.

In general, Caster of Okeanos' CE choices revolve around either boosting her damage via NP Damage Up, or increasing her NP frequency via Starting NP Gauge. Buster Performance Up effects can also be used in combination with the aforementioned effects, though these modifiers are typically weaker than NP Damage. Lastly, if Caster of Okeanos is used as an Order Change Servant, Masters can boost her support by using CEs with On Entry, On Death, or Taunt effects.

• The Black Grail / Hero Elly’s Adventure / Heaven’s Feel: These CEs provide the largest raw damage increase overall and are best used with well-supported teams.

• Kaleidoscope / The Imaginary Element / Dragon’s Meridian: The use of these CEs helps Caster of Okeanos fire several NPs in succession very early on, excellent for stages with multiple lower-health bosses, low HP Break bars, or when disables are required.

• Aerial Drive / Holy Night Supper / Golden Sumo: Boulder Tournament: Hybrid Starting NP Gauge CEs with secondary offensive effects can be used in place of the above options, especially when NP charging supports are abundant.

• Golden Captures the Carp / Ox-Demon King: These CEs should be used when Order Change strategies are employed, allowing Caster of Okeanos to provide additional offense for the team from the moment she steps onto the battlefield.
