Grim Pursuit - Rengokutsu Guide

Rengokutsu is one of the Grim Pursuit bosses. In this guide you will find tips how to deal with him!
Rengokutsu Overview
- Boss Name: Rengokutsu.
- Element: Odd.
- Challenge Type: Grim Pursuit.
- Difficulty Tiers: Nightmare → Hell → Inferno.
- Key Threats: Damage Taken Increase and Extra Attacks.
- Alternating Units Disadvantaged: The generic disadvantages apply against a weak Affinity, but Rengokutsu and his add-ons change their type multiple times during the fight.
Shell Drops
Here are the Shells dropped by the boss:






Skills Overview
Fire Blast
Rengokutsu scatters flames to deal 600% damage to a single enemy. When attacking an enemy with a countered Affinity, has a 100% chance to steal 20% Turn Meter.
How to counter?
- SPD buffs and Turn Meter buffs help offset the constant stealing of Turn Meter by the Boss. [Ave Maria] from Chiaki the Echo prevents Turn Meter Steal too!
Ascending Flame
Be consumed by raging flames! Rengokusatsu deals 600% damage to all enemies, ignoring 25% DEF; when attacking an elemental-weakness enemy, ignores 40% DEF and clears their Turn Meter. After casting, changes all allies' elements in the order: Reason > Odd > Hollow > Disorder > Constant.
How to counter?
- Focus HP more than DEF. The attack only becomes scary after multiple stacks of Debuff have been applied on your team.
Dark Desire
Passive. Each Time enemies of the same Affinity take a total of 4 turns, Rengokutsu deals 400% damage to those enemies and applies [Evil Fire]. Each stack of [Evil Fire] increases damage taken by 20%.
How to counter?
- Bring Units of as many different Affinity as possible. In the worst case, make sure that your DPS and squishies have a different Affinity than your faster units. Follow Up Attacks do not count towards the count.
Team Composition Tips
Rengokutsu is, in essence, not a complex or dangerous boss. What makes him scary is the steadily stacking Debuff that can turn his initially average damage into nukes way too heavy for your healer to handle. For that reason, like most of the Shell bosses, steady damage and healing outputs are key:
- Healer/Support - Most of the damage targets either 1 or 2 Units at once every turn, so prioritise supports that can target multiple Units regularly. Since the [Evil Fire] Debuff cannot be countered, there is no need for a cleanser. Instead, aim for big Heals/Shields.
- DPS - While the add-ons can be problematic, their presence isn’t all too bothersome so you can focus more on single target damage.
- Fangus andObol even though AoE oriented, are perfect for the job;
- RosaKhlorosMassiahVictor are great examples of powerful Single Target DPS, but depend more on rng and/or good gear than the DoT spammers since the Affinity of the Boss matters more for them. A glass cannon Massiah relying on Invincibility can get one shot during the Disorder Affinity phase of the boss for example.
- Buffer - Turn Meter buffs, SPD buffs as well as other offensive buffs all work well here as there is no dispel and the fight is a race against the boss:
- Chiaki [The Echo] andFreya are once again highly recommended, thanks to their constant buffing potential and ease of use.Beyontin works great with multiple geared DPS whereasTsukiyo Mi is better for a single hyper carry.
- KlossGrayDinah all bring offensive Debuffs while accomplishing multiple roles in the team.
- Tank -Lastly, as with all Shell bosses, Rengokutsu is vulnerable to [Taunt], which offers an excellent way of mitigating his AoE potential.
