Infernus is a fiery hero who uses flame control and a literal fingergun to boost his speed and ignite his foes.

Infernus’s abilities explained#

Infernus has three regular abilities and an ultimate. Ability names and behaviour below were checked on 27 Oct 2026; numbers are left out on purpose because they change with almost every patch — the in-game tooltip shows the current values.

Napalm ability icon

Ability 1

Napalm

Spews an incendiary mixture that deals spirit damage, slows targets and coats them in napalm. Coated targets take extra damage and have reduced healing.

Flame Dash ability icon

Ability 2

Flame Dash

Dashes forward with slow resistance while leaving a burning trail that deals spirit damage over time. Holding forward carries Infernus farther.

Afterburn ability icon

Ability 3

Afterburn

Weapon hits build up a burn that deals spirit damage over time. Ability casts refresh the burn, and weapon hits extend it.

Concussive Combustion ability icon

Ultimate

Concussive Combustion

Turns Infernus into a living bomb that, after a short delay, deals spirit damage and stuns nearby enemies. Once cast, it cannot be interrupted.

How to play Infernus#

Keep fights mobile — hit, reposition, hit again. Your kit rewards picking the moment to commit, not standing in one place.

Tips from the current kit

  • Pair Flame Dash with Napalm to chase down and ignite enemies.
  • Keep landing weapon hits to build and extend Afterburn.
  • Hold forward during Flame Dash to travel farther.
  • Cast Napalm or items during Flame Dash without breaking it.

Build framework#

A starting framework, not a tested build

This section explains what kind of items Infernus’s kit rewards, built from how the abilities work. It isn’t a win-rate-tested build. For community builds with current stats, open the in-game Build Browser and filter by hero, then check our items explainer to understand why each item is there.

Spirit lean. Most of the kit's damage is spirit damage from abilities, so spirit power, cooldown reduction and duration usually do the most for it.

Infernus build framework · 27 Oct 2026
StageWhat to look for
LaningCheap 800-soul items that help you trade and sustain in lane, plus one that boosts your main damage source.
Mid gameYour first 3,200-soul item is usually the biggest single jump in power — buy toward the one that makes your best ability or your gun stronger.
Late gameFill slots with 6,400-soul items, and swap cheap starters for upgrades. Leave room for an answer to what the enemy is doing.
DefenceMatch the enemy’s damage: shields and resistance against whichever type is hurting you most.

Items that fit a spirit kit

Defensive options

Items opponents commonly use against Infernus — expect to see them, and plan around them:

Ability points#

Ability unlocks come from levelling up; ability points then buy upgrade tiers. A sensible default for Infernus:

  1. Unlock the ability that helps you farm or trade in lane first — for most players that’s Napalm or the ability you can hit most reliably.
  2. Unlock all three regular abilities early so you have every tool in the first fights.
  3. Unlock Concussive Combustion as soon as it’s available.
  4. Put upgrade points into the ability you use most, then into whichever upgrade tier changes how an ability works (tier 3 upgrades often do).

General guidance; upgrade tiers and costs are shown in game.
