Guide

Character Intro

Rikuhachima Aru is the adorkable boss of Problem Solver 68 club. She aims to be the coolest “outlaw” in Kivotos and cause chaos in mischief that typically backfires on her and her crew due to her constant blunders. Though she may look like a hard-boiled outlaw on the outside, she is a soft kind-hearted girl on the inside who thinks of people first.


Character Overview

Aru is a Sniper who deals AoE Explosive Damage. She works best against grouped clusters of enemy units.

Her EX Skill (Hard-Boiled Shot) will deal two instances of damage, the second instance hitting enemies in a circular AoE damage. Meanwhile, her Basic Skill (Noir Attack) is a mini-version of her EX Skill that relies on a 50% chance to deal an AoE damage. 

The rest of Aru’s kit aims to improve her overall damage output by buffing her Crit DMG and Crit rate. Combined with Aru’s high EX skill multipliers allows her to output large amounts of Explosive damage.

At high investments, Aru can be an extremely potent Explosive DPS with her EX Skill and Basic Skill. At Unique Equipment Lvl 40, her Enhanced Skill, The Gravity of a Boss+, adds a flat Crit DMG boost to her pre-existing percentage increase.

With her Unique Item, Aru’s Very Precious Wallet equipped, she gains a decent accuracy buff and allows her Basic Skill (Noir Attack) to guarantee its extra AoE attack.


Strengths

  • Good in both extreme and insane Light armor raids.
  • High Explosive AoE and Single Target damage
  • Farmable (Hard 18-3)

Weaknesses

  • AoE for EX Skill is relatively small compared to other EX Skills.
  • Low DPS output when unable to use EX skill.
  • Her Basic Skill has a 50% chance to activate.

Skill Review

EX Skill

Hard-Boiled Shot

EX Skill
Fires a shot that deals 274% damage to one enemy and explodes for an additional 292% damage to enemies in a circular area around the target.

Deals a single instance of damage to her target, followed by a small explosion that damages any enemy units caught in the blast. Her EX Skill is relatively small so it would be best if she targets large groups of enemies. 

While Hard-Boiled Shot has an extra AoE damage, it can be used as a powerful Single Target attack when used against Light armored bosses.

Basic Skill

Noir Attack

Normal Skill
Every 25s, fires a shot that deals 152% damage to one enemy with a 50% chance to explode for an additional 251% damage to enemies in a circular area around the target.

Skill leveling priority: 2

Deals damage to a single target, it has a 50% chance to detonate a small AoE explosion.

This can be inconsistent due to part of her Basic Skill’s damage being reliant on chance.

Enchanced Skill

The Gravity of a Boss

Passive Skill
Increases CriticalDamage by 14%.

Skill leveling priority: 1

Buffs Aru’s CRIT DMG by a decent amount.


When paired with Aru’s Basic and EX skill, it allows her to dish out a significant amount of burst damage.

Sub Skill

Way of the Outlaw

Sub Skill
Increases CriticalChance by 20.1% for the duration of Aru's EX skill.

Skill leveling priority: 3

Buffs Aru’s CRIT Rate by a decent amount


Gameplay Progression

Early game: During the early game Aru can be used as boss killer and wave clearer. However it can be difficult to control the targeting of AoE due it being centered around single target.

Early game alternatives:

AoE:

Students listed here are some of the notable options available.

Single Target:

Students listed here are some of the notable options available.

Late game (High Investment): Aru's High EX multipliers combined with self crit buffs makes her a great choice for Light raids, such as Kaiten (specifically at Phase 1).

  • Minimum recommended investment: Unique Equipment Lv40
  • Skill leveling priority: Enhanced > Basic > Sub

Character Notes

  • Most of Aru’s damage is frontloaded in to her EX skill, In teams where she cannot cycle through her EX skill her damage will have a significant drop.
  • Having CRIT Rate built into her kit helps her consistency against enemies with high CRIT Resistance.
  • Can be used in conjunction with a student that has a taunt/pull to maximize Aru’s EX skill damage(e.g Tsubaki reference found in raid showcase).

Conclusion

Overall, Aru is an excellent Explosive Sniper who can be used in both AoE and Single target content. Her EX Skill is great against large crowds of enemies when paired with her Enhanced and Sub Skill. It is also advisable to plan out your team skill rotations as most of Aru’s damage comes from her EX skill.

Aru’s damage from her Basic Skill can be inconsistent as you’ll have to rely on a coin flip whenever she would activate her Basic Skill’s extra effect or not. This can be mitigated with Aru’s Very Precious Wallet.

How Much Should I Invest?: Unique Equipment level 40 or 50. The CRIT DMG bonus stat on her Enhanced Skill greatly enhances her damage when combined with her Sub Skill. On a side note, it is recommended to get Aru's Bond to 25.

Should you pull on her banner?: Not recommended to pull, she's part of the standard pool and is also farmable.
