Caster of the Nightless castle or CON as we’ll call her is far from perfect. Boasting base stats of an incredibly weak attack stat, hitting around 9000 Attack, she tries to make up for it by having an HP stat of almost 16000. While it is true that caster servants shouldn’t care too much about their attack stat anyways due to their 0.9x class multiplier, it still hurts her damage output. This is made slightly better by her passive skill territory creation which provides her a 12% boost to her arts cards.

CON’s generation stats are ok, with a decent NP gain on her arts cards, which are boosted by her passive skill territory creation. However, having a deck that contains 3 Arts cards definitely helps her generate decent levels of NP. Her stargen is decent as well, pulling around 20 stars on an ABQ chain, which is around the average for her class.

Her skillset is slightly muddled, as if she could not decide if she was going to be tanky or offensive, landing somewhere in the middle, and not in a good way. Though if one were to hazard a guess as to her role, that role would be of a disabler on a stall team. Scheherazade's skills are not hard stall skills and honestly that's the most painful part, but what she does offer allows her to scrape by 1 more turn so she can race her enemies to her NP. With the addition to her third skill through her 2nd interlude, Scheherazade now has a more varied support role by providing a team wide guts effect.


  • Strong in very specific situations and only when spamming her NP
  • Decent gen stats for her class
  • Decently spammable NP along with survivability in kit


  • Pitiful attack stat for a servant with an offensive NP
  • She needs support in terms of NP generation
  • All her skills are mostly selfish

Strategies & Tips

CON will enjoy being paired with a team of servants who have an Arts focused decks. These will help CON generate more NP so as to keep spamming her NP against enemies. She will also enjoy any teammates who can further boost her attack or defense stats,ensuring that she stays alive and that she pushes out more damage to enemies. Her first skill should be used to stall for turns or as an Arts buff, allowing her to gen more NP or do more damage on her NP. Her second skill should mainly be used for stalling purposes, allowing her to charm male targets on top of giving herself a very strong defense buff, allowing for a more defensive stance against enemies. Her last skill should be used to protect herself from being killed. This can also be used to drop the attack of any enemies with the king trait. While it sounds pretty niche, there are a large number of servants with this trait and can be applied more often than most think.

Noble Phantasm

Alfu Laylatin wa-Laylah is an AOE Arts attack which deals extra damage to all enemies with the King trait. This skill does great amounts of damage to a specific group of enemies, allowing her to go on the offensive in spite of her low attack stat. However, against enemies who do not have this trait, this does close to no damage, barely even being able to hit 30000 damage.

Best Servants to Work with

Tamamo no Mae
Tamamo no Mae
Tamamo is an excellent caster to be paired with CON. She helps cover for CON’s weakness, her NP allowing her to reduce cooldowns on CON’s skills, allowing her to use her skills more often than normal. Tamamo’s art buffs also increases CON’s damage and her NP gen which helps with her main concerns.
Gilgamesh (Caster)
Gilgamesh (Caster)
Gil is a good choice, fielding with a large amount of arts cards in his deck. This allows him to Arts chain together fairly easily. He also provides an Arts buff to the team as well as a flat attack buff, allowing for the damage output on the team to be increased.
Zhuge Liang
Zhuge Liang
Waver can fill up CON’s NP gauge easily, making it easier for her to NP much faster and easier than ever, on top of having an Arts focused deck. He also has a flat attack buff, making her damage output rise marginally.

Best CEs

Cute Orangette
Cute Orangette
Cute orangette is a fantastic CE for CON, allowing her to improve her not so fantastic NP gen while also boosting her NP damage which is her main source of damage output. This allows her to spam her NP easily so as to deal damage to her opponents.
Formal Craft
Formal Craft
Formalcraft gives CON a flat boost to her biggest source of damage, Arts cards. This allows her to deal more damage to her enemies through her most common card type on top of allowing her to push out higher numbers on top of having higher numbers in terms of NP generation.
The Black Grail
The Black Grail
Black grail boosts her NP damage at the cost of some HP every turn. This works in CON’s favour due to her large HP base stat. This means that the CE will not majorly affect her survivability while also allowing her to increase the numbers delivered by her main source of damage.

  • Survival of the bedroom A+

    This is CON’s main survivability skill, boosting her defence skyhigh, allowing her to stay on the field much longer than she can without it. It also has a built in charm which while it is not very effective in most situations, it can be helpful in certain situations. This skill should be levelled second.
  • Counter hero A

    Counter hero is a buff that gives CON a typical guts skill, allowing her to survive any killing blows while also dropping the attack power of any enemies with the King trait. While it may not apply to all enemies, it is helpful in a pinch. This skill should be levelled last.
