NieR Re[in]

Guide

As with all dark memory character costumes having an affinity-based damage reduction passive, each of Reborn Princess, Reborn Revolutionary, and Reborn Inmate have the Void Guard passive ability capable of negating up to 25% of received Dark damage. This can be invaluable to have in the later quests within Shadowy Cave, especially for the handful of quest missions that require to “clear while each of your party member's HP is at least over 80%”, and even more so for the 2-character only missions.

• As a whole, Reborn Princess (EX Fio) is probably worth the most out of the three for the effort of obtaining between the her weapon and the costume itself. Her character skill is certainly powerful, but will also self-heal for 50% HP; even without a dedicated healer, Fio will likely be the last to go down.
• Reborn Revolutionary (EX Rion) serves as a great support and tank - while his healing and damage from his character skill isn't as potent as Reborn Sorceress (EX Saryu), his Void Guard will likely keep him in the battle for longer for this event.
• Out of the three here, Reborn Inmate (EX F66x) will likely see the least utilization for Shadowy Cave. While her CS does decent damage, the stun won't be very useful for the bosses, as they're… ahem, immune to stuns. However, the value and effort it took to get this costume is more so found in her weapon - more on that further below.

Support comes in many forms, whether its a healer, tank, or damage buffer; these few will likely do well depending on the enemy/boss combination at hand:

• With the recent wave of costume adjustments, Abstract Captive just received more than a few buffs. While she still heals the party for 40% HP with her character skill, it takes less time to build and also provides a temporary defense buff (while using a light main weapon, which you should definitely be doing…) Her HP-Up passive now extends to the whole party as well!
• Reborn Sorceress (EX Saryu) makes for a great healer/tank - while she excels mostly against fire-affinity enemies, her raw combination of HP, healing, and decent damage output for a support are still valuable.
• Yuletide Monster is also the recipient of costume improvements - Levania's character skill now adds an attack buff along with the already implemented light-damage bonus, and his passive now offers a bit more attack for the whole party.

There are so many damage-dealers available that none of the below suggestions are 100% needed, but there are a few recent costume additions that appear to excel specifically well for outputting light damage:

• Yurie's Abstract Ruler costume brought in a rare combination - high attack, light-affinity, and a gun. Her Lucid Drive will bring her attack levels to incredible levels, and her character skill will certainly help pile on more with both a defense debuff and light-damage received debuff.
• The new addition of Abyssal Soldier won't surprise many: long cooldowns with heavy attack. As long as the weapon skills can be utilized quickly enough to build his character skill. You'll likely see Lars hitting the damage cap multiple times over - a good way to finish off bosses without dealing with their desperation attacks.

• While Reborn Princess shows her own value, even a non-fully-evolved Cadeau Royal can serve as one of the best light-affinity DPS weapons, and finishing off a combo with a decent defense buff can keep your characters fending off multiple waves of damage.
• A fully evolved BSE_TypeMW is arguably more valuable than the costume it makes accessible (EX F66x). Once fully evolved, having access to a 20% HP party-heal with only a 23-second cooldown (and even less than that with Haste also available) is a literal game-changer.
• Blackhorn Mourning could be used as a main weapon, but it'll more than likely be found equipped as a sub-weapon to a character that doesn't have a Void Guard passive.
• For those that like to “rip” through the enemy's attack power, you'll find the Blade of the Lost Seal has more than a few uses. Along with Bold Vigor and Lucid Boon passives, this weapon has the potential to keep perpetual stacks of lowered attack & defense on an enemy if multiple copies of it are within your grasp.
