Blood Hunt's upgrade system throws a lot of terminology at you fast, and Output Boost is one of the stats that's easy to scroll past without understanding. That's a mistake. This single stat applies a damage multiplier to every attack your hero lands, making it one of the most impactful numbers on your entire character sheet.
What does Output Boost actually do in Marvel Rivals Blood Hunt?
Output Boost is a universal bonus damage multiplier. It provides an extra amplification to all damage dealt, which gradually tapers off as the total amplification value increases." The key phrase there is “all damage dealt”, this isn't limited to one ability or attack type. Every hit you land benefits from it.
The taper is worth understanding too. The stat uses diminishing returns, meaning each additional point of Output Boost is slightly less effective than the last. The value displayed in your Hero stats already reflects those diminishing returns, so you're always reading the final effective number rather than a raw figure.
Because Output Boost applies to all damage, it scales equally well on every hero. A healer dealing chip damage benefits just as much as a DPS spamming abilities.
Output Boost in hero traits
How to check your current Output Boost
The stat is a bit buried, so here's the exact path to find it:
- Open the Blood Hunt event page
- Select the Hero tab
- Switch to the Traits section
- Look for "Total Output Boost" near the upper left corner of the screen
Each hero has their own separate Output Boost value since you build and upgrade them independently. Checking this number before entering a harder difficulty run is worth the few seconds it takes.
Output Boost totals differ between heroes. A hero you've heavily invested in will show a much higher value than one you've barely touched, even within the same account.
How to increase Output Boost in Marvel Rivals Blood Hunt
The only way to raise Output Boost is by spending points in each hero's skill tree under the Traits page in the Blood Hunt section. The specific nodes to target are called Output Amplification. These nodes can be leveled up multiple times, so keep returning to them as you earn more upgrade points.
Output Amplification nodes stand out from ability-specific upgrades because their benefit isn't locked to one part of your kit. Whether you're playing Moon Knight, Blade, or Squirrel Girl, stacking these nodes consistently outperforms narrower upgrades when you're pushing higher difficulty tiers.
Why Output Boost matters for hard bosses
The toughest encounters in Blood Hunt, specifically the Dracula boss fight and the hidden Kingpin boss, are the clearest test of whether you've built your hero properly. High Output Boost means your team's damage phases move faster, which directly reduces the time you spend exposed to their most dangerous attack patterns.
Building Output Boost on the strongest characters available in Blood Hunt is the most reliable path to clearing those fights and unlocking the exclusive rewards tied to them, including the Kingpin Accessory.
