Overview
Diesel

Vindicators
Advanced Elite
Single Damage
Debuffer
4: Position 4 is Diesel’s optimal slot where he fires after tanks have absorbed initial aggro, delivering Scythe Chain’s 3 hits and stacking Flame markers and healing reduction from a protected position.
3: Position 3 lets Diesel act earlier in the turn order for faster Flame marker accumulation, useful when you need healing reduction applied before enemy healers can act.
5: Position 5 provides maximum safety but delays Diesel’s action, viable in lineups where another hero occupies position 4 and Diesel is a secondary damage dealer.
Diesel is the Vindicators’ anti-heal and anti-shield specialist whose Scythe Chain delivers 3 hits of 100% WPN DMG to random enemies while Blazing Flame Marker detonates at 3 layers for 20% max HP damage, and Terrible Cuisine reduces enemy healing given and taken by -10% per hit stacking to -50%. His Frostbite Scythes UW zeros enemy shields on Flame marker detonation and applies +20% increased damage taken, making him the hardest counter in the game to shield-reliant compositions. Pursuit after Delicacy punishes any enemy heal or shield with a free 100% WPN DMG attack, ensuring Diesel’s anti-sustain pressure is constant and unavoidable.
Pros & Cons
- Terrible Cuisine stacks -10% healing given and taken per hit up to -50%, completely shutting down enemy sustain over 2-3 rounds
- Flame marker detonation deals 20% max HP damage (capped at 800% ATK), making Diesel effective against high-HP tanks
- Frostbite Scythes UW zeros enemy shields on detonation and applies +20% increased damage taken, hard-countering shield-reliant compositions
- Pursuit after Delicacy punishes every enemy heal or shield with a free 100% WPN DMG attack, providing constant anti-sustain pressure
- Flare exclusive gear grants +10% Initiative and targets highest-shield enemy first with Scythe Chain, ensuring anti-shield pressure hits the right target
- Conditional kit loses significant value against lineups that don’t rely on healing or shields
- Low VIT (299) makes Diesel fragile and reliant on front-line protection for survival
- Flame marker detonation requires 3 layers to trigger, meaning 3 separate hits on the same target before payoff
- Flaming Chain’s -200 Focus reduction only activates if the target received a shield or heal, making it situational
Skills
Diesel throws a flying axe to entanglea random enemy, dealing 3 hits of damage, each hit dealing 60/68/76/84/100% WPN DMG.
Every time Diesel deals damage to an enemy, applies a layer of Flame marker; when the Flame markers reach 3 layers, the markes will be detonated in the subsequent attack, additionally dealing some damage equal to 12/14/16/18/20% of the maximum HP; note that the additional damage shall not exceed 600/650/700/750/800% of the ATK.
Each time an enemy unleashes a healing or shield effect, Diesel will make an additional attack against that enemy, dealing some WPN DMG equal to 60/68/76/84/100% ATK. This effect can be triggered only once per round.
If the enemy targeted by the fatal skill already received a Shield or healing effect within the ongoing round, additionally reduces the target’s Focus by 120/140/160/180/200.
Every time Diesel deals damage to an enemy, additionally reduces the healing effect given and taken by this enemy by 5/6/7/8/10% for 2 rounds, stackable for up to 5 layers.
Gear
Flare is mandatory for Diesel to unlock Scythe Chain’s shield-targeting priority and +150% WPN DMG. Pair with Resolute for survivability or Reaper for maximum burst. The +10% Initiative ensures Diesel applies healing reduction before enemy healers can act.
Diesel’s exclusive set granting +10% Initiative for earlier action and Scythe Chain targeting the highest-shield enemy first. 4-piece adds 150% WPN DMG to Scythe Chain for massive burst on anti-shield targets.
#1 Best
Versatile set providing WPN DMG and death immunity, ensuring Diesel survives long enough to stack Terrible Cuisine’s healing reduction to maximum value.
#2
High-damage endgame set amplifying Diesel’s raw WPN DMG output, pairing well with Flare’s enhanced Scythe Chain for maximum single-target pressure.
#3
Aggressive damage set maximizing burst at the cost of survivability, best when the lineup has strong healing and tank support to compensate for Diesel’s fragility.
#4
Offensive alternative providing raw damage bonuses, viable as a secondary set when other options are allocated to higher-priority heroes.
#5
Pure offensive set boosting kill potential, especially effective when Diesel crits on Flame marker detonations for devastating burst against shield-stripped targets.
#6
Diesel’s substats prioritize STR and DMG Bonus on weapon and jewelry to maximize Scythe Chain’s burst damage, while helmet and body focus on survivability for his fragile 299 VIT stat line. Crit Rate is particularly valuable since critical Flame marker detonations combined with shield zeroing create devastating burst windows.
DMG Bonus, STR, Crit Rate
DMG Bonus and STR directly scale Scythe Chain’s 3-hit burst and Flame marker detonation damage, while Crit Rate increases the chance of devastating crits on detonation hits.
HP%, AGI, VIT
HP% and VIT compensate for Diesel’s low base VIT (299), while AGI improves action order to apply Terrible Cuisine’s healing reduction before enemy healers activate.
DEF, VIT, DMG Mitigation
Defensive substats protect Diesel’s fragile stat line, ensuring he survives long enough to stack Terrible Cuisine to -50% healing reduction across the enemy team.
DMG Bonus, STR, Crit DMG
DMG Bonus and STR maximize Scythe Chain’s raw damage, while Crit DMG amplifies critical Flame marker detonations that zero enemy shields via Frostbite Scythes.

Interactions with other heroes’ ultimate weapons.
Hellfire Axe’s permanent Backlash stacking draws enemy attacks toward Casino, protecting Diesel’s fragile stat line while Casino’s focus drain compounds with Diesel’s anti-heal for dual disruption.

Counters
- Burst Damage Lineups (Hard Counter) — Lineups that kill Diesel quickly bypass his stacking anti-heal mechanic, since Terrible Cuisine needs 5 hits to reach -50% healing reduction and Flame markers need 3 layers per target.
- Lineups Without Healing/Shields (Hard Counter) — Against compositions that don’t rely on healing or shields, Diesel’s entire anti-sustain kit becomes irrelevant, leaving him as a mediocre single-target damage dealer with no utility.
- High-Initiative Lineups (Soft Counter) — Lineups that act before Diesel can apply Terrible Cuisine may land kills before healing reduction takes effect, bypassing his disruption window.
- Healing-Reliant Lineups (Hard Counter) — Terrible Cuisine’s -50% healing reduction combined with Pursuit after Delicacy’s free attacks on every heal creates devastating anti-sustain pressure that healing-focused compositions cannot overcome.
- Shield-Reliant Lineups (Victoria) (Hard Counter) — Frostbite Scythes UW zeros enemy shields on Flame marker detonation and applies +20% increased damage taken, completely invalidating shield-based defense strategies.
- Hybrid Sustain Lineups (Soft Counter) — Lineups that use both healing and shields are doubly punished by Diesel, as Terrible Cuisine reduces healing effectiveness while Flame detonations zero shields simultaneously.
Rating
A Tier. Diesel is a powerful niche counter-pick from Dimension X5 onward who hard-counters healing and shield compositions but loses value against lineups that don’t rely on sustain mechanics. His Flame marker detonation for 20% max HP damage and shield zeroing make him devastating in the right matchup, but his conditional kit means he lacks the universal impact of S-tier heroes.
