Kama

Kama primarily serves as a Challenge Quest beast with high damage and multiple Quick Noble Phantasms which charms her enemies. In order to use this, she must prioritize skills boosting her looping potential first, then deal with her damage.

• Blessing of the Goddess B is a rare skill in the game which grants an overcharge for any ally. Typically, Kama will use this overcharge on herself to boost her Quick bonus for three turns. It comes with a reduction of 1000 to Max HP, although if she’s damaged this may come as a boost as she also heals a lot of HP from the skill’s third effect. This can be left for last as it has the least damage gain, although it should be leveled to max to get the full heal boost.
• Ananga EX has a two-tiered boost in both an unlimited-turns guts and a basic 3-turn attack boost. It is the most simplistic of her skills and saves her in Challenge Quests. As Kama wants the maximum possible boost to attack, she should level this to max, secondary only to the charge. As an added bonus, the reduced cooldown at higher levels may make it possible to get the Guts skill back up more quickly if it ends up being consumed.
• Mara Pāpīyas EX is the skill that makes Kama one of the best in the game. The 50% charge gives her an ability to loop, the charm resist debuff makes her Noble Phantasm’s charm stick instead of being chance based, and it gives her the rare advantage against Alter Ego enemies. Its Critical damage boost is rarely useful, but does exist. Level this first and to max.

“Don't you dare treat me like those other child Servants. ...Hey wait. I'm not saying that I DIDN'T want that piece of cake you're holding.”

Once upon a time there was a need for a goddess who wanted to help Master explore any pleasure they desired, no matter how depraved it may be. So Kama came alone with a Quick Single Target Noble Phantasm with a high chance of charming its target, and became the premiere Challenge Quest DPS in the game for a long time. That way, Master can always find the pleasure they seek in winning the game.

Kama comes to be in the middle of the Quick-Meta stage of the game, and given her kit, reaps many benefits within that meta. Her Noble Phantasm is the biggest feature of all of this which, besides doing a very large amount of damage, has a very high chance of immobilizing an enemy for a turn via charm. And that’s not even mentioning how she can chain Noble Phantasms with its built-in Quick buffs to make successive Noble Phantasms even faster. And why can this girl use successive Noble Phantasms? She has a  super-rare feature for an Assassin: a 50% charge skill on Mara Pāpīyas EX! Of course, one must also mention her non-turn limited Guts skill on Ananga EX which can also be supplemented by Blessing of Goddess B’s huge heal to bring her back up to health. And then there is the fact that she can manipulate her class advantage, becoming one of the only Servants capable of gaining class advantage against Alter Egos.

With all those strengths, it’s hard to find any weaknesses in Kama, but they’re there. Most notably, she’s lacking in critical capacities save for a small critical damage buff. In addition, she lacks an ability to ignore invincibility and defense, occasionally making her competitors more viable. 

With one of the most solid arsenals in the game for a damage dealer, nobody should ever not want Kama in their party for her sheer survivability, damage, and stall potential. Those three combined together make her a challenge quest beast, while still being a strong contender as primary damage dealer in non-challenge quest scenarios to take out a single larger enemy, or as a team anchor. Just make sure to save her a piece of cake for when the quest is done!

High Damage

Despite Kama’s innate 0.9x multiplier due to her Assassin classing, she is one of the heaviest damaging Single Target Servants in the game. Not only does Ananga EX give her a strong attack buff for three turns, and not only does Riding A give her a Quick bonus, but she gains further bonus for 3-turns from her Overcharge’s Quick boost. If she can do multiple Noble Phantasms, any further one will continue to grant stacks of Quick boosts. With Skadi in play, this leads to insane damage numbers. She’s also great against Alter Egos, capable of hitting them with full class advantage with her Mara Pāpīyas EX boost up.

Durable

It’s hard to bring Kama down. She has a Guts on Ananga EX which does not expire, and Blessing of the Goddess A heals almost 1/3 of her HP every time she uses it. To make matters better for her, it’s hard to hit her back because she has an 80% chance to charm enemies each time she uses her Noble Phantasm. With Mara Pāpīyas EX’s +40% charm chance, she can guarantee the charm against almost any enemy in the game for a turn.

Quick Looping

Kama has high hit counts, and despite being Single Target, she has decent refund on her Noble Phantasm. Like all 50% chargers, she can loop for 3 turns with a MLB Kaleidoscope, 2 Skadis, and a Waver. But due to her high hit counts and the guaranteed overcharge on her first skill, she can at times regenerate enough charge in a turn to not require a full 50% charge.

Low Innate Critical Capabilities

Kama can use her bonuses from Skadi critical bonuses to boost her Critical damage, but without a Skadi she has very little in the way of Critical boosts. She has only a 20% boost on a skill and Independent Action C, meaning she can’t provide much in the way of a Critical hit. She also is lacking Critical star generation passives, although that is partially relieved with her high hit counts. 

No Sure Hit

There are not many single-target Assassins in the game with a self-charge skill. Those who have it have the capability to ignore invincibility and defense, making their attacks unavoidable. Unfortunately, Kama has no such ability, making it possible to avoid her Noble Phantasm at the wrong time.

As a damaging Servant, Kama uses the standard CEs to give her the ability to unleash more Noble Phantasms and to hit harder. Starting Noble Phantasm Charge CEs will enable her to get early access to her Noble Phantasm. Mixed Noble Phantasm / Damage CEs can help her damage numbers while still giving her the same early access. Noble Phantasm Damage Up CEs can boost her damage even further on the cost of a potential loop.

• Kaleidoscope / The Imaginary Element / Dragon’s Meridian: By using a starting gauge CE, Kama can potentially do 3 Noble Phantasms in 3 turns, especially with a MLB Kaleidoscope. Even if Masters don’t have the Skadi or Waver needing to do so, she still gets fast access to that Noble Phantasm and a decent enough refund.
• Holy Night Supper / Knights of Marines / Golden Sumo: Boulder Tournament : While it’s good to have a starting charge, CEs which boost damage can provide the best of both worlds. With the right face cards, Kama might be able to use one of these CEs and a Skadi / Skadi / Waver setup and still loop for three turns against a bulky enemy. 
• The Black Grail : If one does not want to attempt three Noble Phantasms in three turns, and instead wish to boost raw burst damage,  this CE is one of the best for improving Kama’s Noble Phantasm damage. This will take her already high damage and bring it to even greater heights.
