A 5-star Heat Caster that flexes between two very different jobs. Played as a damage dealer he is somewhat limited, since his output is mostly single-target and lower than dedicated carries, but reworked as an Infliction support he becomes far more valuable: he hands the team two stacks of Heat Infliction and can force Combustion with his Ultimate, enabling stronger Arts Reactions for allies.
This build treats Wulfgard as a Combustion damage dealer whose real strength is amplifying the burn rather than hitting hard with raw attacks. Rational Farewell supplies the attack stat that his Combo Skill can activate on demand, and because that weapon's buff also improves with Potential investment it keeps scaling if you keep investing in him. The Hot Work set leans on Arts Intensity, which feeds the Combustion damage-over-time, and its Heat damage window triggers naturally whenever he applies Combustion, so his normal rotation keeps the bonus running. A Bonekrusha wristband fills the remaining slot because its attributes line up with his stat needs and it lifts Heat damage on every source. Because so much of the output arrives as damage over time, this is a sustained-damage setup rather than a burst one. If you swap to Clannibal you gain a different ceiling but must micromanage when to consume Combustion; Wedge and Long Road are the simpler fallbacks for players without the premium options.
Insights
Core Mechanics
- Heat Infliction is his main contribution: both his Battle Skill's final shot and his Frag Grenade·β Combo Skill can tag enemies with it.
- Casting Thermite Tracers on a target already holding Combustion or Electrification consumes that reaction to fire an extra high-multiplier shot instead of applying Infliction.
- Wolven Fury, his Ultimate, forcibly applies Combustion to nearby enemies, which is what lets him enable allied Combo Skills.
- His passive Scorching Fangs activates whenever he applies Combustion, giving him a flat boost to Heat damage dealt for a short window.
Scaling
- Early on he has no access to cooldown-reducing gear, so building him for raw damage is the more practical path.
- At endgame his support ceiling scales with Combo Skill cooldown reduction and Ultimate Gain, letting him push out Inflictions more frequently.
- His damage profile stays narrow because his biggest hits depend on consuming an existing reaction rather than on his own rotations.
Team Role
Wulfgard can be slotted in as either a damage dealer or an enabler, and the correct half of his kit to lean on depends on the team. When he is the damage source, he wants to be controlled directly so that his Combo Skill lands first to produce Combustion, followed immediately by the Battle Skill to consume it for the extra shot; this ordering also keeps Scorching Fangs up. In that role he prefers compositions that already lay down non-Heat afflictions so his Combo Skill has something to react with, and he stays best against single targets. As an enabler he steps back from the driver seat: he feeds two Heat Infliction stacks plus a forced Combustion from his Ultimate, which lets a Heat-focused ally like Laevatain convert those into her own enhanced resources. This version is more team-dependent, valuing cooldown reduction and Ultimate uptime over his personal numbers, and it works best in Arts-Reaction centric lineups that can actually capitalize on the afflictions he spreads.

Explanation
The weapon is chosen because its Pursuit effect delivers a large attack increase that his Combo Skill can reliably switch on, and the buff grows further as his Potential level rises, with the 5-star copy obtainable through Arsenal Exchange.
The Hot Work set is taken for its Arts Intensity and Heat damage bonuses, the first of which matters because Combustion is a damage-over-time effect that scales off Arts Intensity; the set's Heat damage window after applying Combustion then amplifies both his skills and the burn.
Clannibal is a workable substitute but shifts the play pattern, since it wants him to consume his own Combustion while it is still ticking, which demands tighter timing and more attention.
Wedge serves as a simple stat option and Long Road is the budget pick when higher-rarity weapons are not yet available.
Notes
- Rational Farewell pairs naturally with his Combo Skill, so its attack buff is almost always active during real fights.
- The extra suit piece from Bonekrusha adds Heat damage that applies to both his skills and his Combustion ticks.
- This variant leans into damage over time rather than burst, so it rewards sustained fights over quick clears.
