The newest Alter-Ego might not be unseating the top-performing Servants thanks to her broad kit, but she can sneak in a few tricks thanks to it. Okita shines the most when you’re up against a node where the thing annoying you the most is that you just can’t fit the best characters for the job into three slots.
The best Okita Alter teams use her as a farming specialist or a Crit/NP Hybrid for best results. Prioritize Persistence Skill and a Craft Essence of Knights Dignity for Critical damage.
Skill Leveling Order
While it certainly isn’t wrong to level everything, some skills are just more valuable than others and should be prioritized. On Okita Alter, there’s a clear favorite skill to focus first, but the next two are close.
Start with Persistence, and don’t neglect taking it to Lv. 10. With NP battery skills, every single percentage is important; the difference between a 0% charged NP and 98% is pretty academic. The cooldown is relatively unimportant since you’re unlikely to get two good uses of Persistence since you can’t use it optimally before you want both effects. The star gather rate is also already high enough at level 1. This means if you’re intending to use your Okita Alter exclusively with Kaleidoscope, you can probably put off Persistence until last.
Next, work on Kyokuchi. It and Boundless provide the same magnitude of buff, but Kyokuchi affects five cards in the deck for three turns. Boundless only buffs her NP, but NP damage is a less common buff to source externally. Obviously, this means you level Boundless last. Neither demands a lore if you’re low on resources. Of the two, Boundless likely deserves Lv. 10 more as the decreased cooldown helps its poor uptime while Kyokuchi sports a 43% uptime even at Lv. 9.
Best Craft Essences
The first step when asking yourself which Craft Essence to use on Okita is knowing what you want her to do. While many characters pair extremely well with specific CEs and can use them to do well in a majority of situations, Okita Alter needs to use her CE slot to narrow herself down. Her strongest feature is in a relatively uncommon switch-hitting style. Many characters are well-suited to using their NP in wave 2 and killing a wave 3 boss, but they’re usually very clunky if they try to do it the other way around. Majin Okita has no such problem, but her crit damage leaves a little to be desired.
For raw Critical Damage, the best option is easily Knight’s Dignity. It features a demerit to make up for its very large critical damage buff, but while farming, this should never come up. The intent while clearing this sort of content is efficiency rather than survivability. It’s hard to get much more efficient for your mid-boss clear than a 40-50% buff to the stat you’re missing. This will skyrocket your critical damage and make the shakiest part of these farming runs the easiest. However, it lacks starting charge so you’ll need to provide for that with your support line up.
For a more direct response to the hybrid plan, Summertime Mistress from the Summer 1 Event provides a sizable chunk of crit damage and enough starting NP charge to get to 100% with the average 20% charge supporter. It also features a better stat split, with all of its levels filtering purely into attack, which is ideal for bursty CEs. This makes it the optimal middle ground between fast AoE clearing and crit-based boss kills. The downside is that if you don’t already have one of these, there’s not currently a source for it. Even most similar CEs are from an event; they’re free, but you have to be around at the time.
Finally, while it likely doesn’t hold pole position once you factor in how common attack buffs are from supports, Golden Sumo is probably the single best CE for Okita Alter in a vacuum. We don’t build teams of one character, but Okita herself has no basic Attack buff. Permanent attack buffs are insanely rare from CEs; thankfully Golden Sumo’s secondary effect is exactly what we’d want anyway. It is, again, an event CE so it was free but is no longer available. If you can’t get your hands on it, I wouldn’t recommend other Attack Up options as none of the others feature starting NP charge.
Mystic Code Selection
You can get a lot more specialized performance out of Okita Alter if you have access to Mystic codes suited to her. The big winner is A Fragment of 2004 as all three of its buffs are extensions to Okita’s very poor longevity.
Code: F is a simple NP Damage up that can be traded off with Boundless to give you two strong NPs as opposed to one. Code: U boosts the star weight of only your Buster Cards and therefore allows you to direct your crits into damage more easily. Because of Okita’s poor skill uptime, you want your crits to focus on damage rather than utility; generating a large number of stars or charging your NP isn’t useful if all of your buffs fall off in the meantime. Code: H is just an NP Generation buff, but it goes a long way if used with your high hit Quick cards. Effective use of this MC can make Persistence and Boundless feel a lot like they have two charges and that helps alleviate one of the biggest troubles with Okita Alter, albeit at the cost of your Mystic Code slot.
Support Options
Usually, a particular support option might stand out, but Okita Alter features an extremely balanced kit that is only lacking in the most common support buff. It’s simpler to list the supports she doesn’t work well with; namely Mozart, Tamamo, and CasGil. Anyone else offers something that she can use. The option that is best will end up changing from node to node, even more so than normal. If you were forced to pick a single support set-up for her, I would recommend the Hans-Merlin combo.
