Brenna in Valheim: Miniboss Guide, Attacks, and Drops

 

    Brenna is an aggressive miniboss you'll run into inside the Smouldering Tombs, a Black Forest dungeon, and she does not play like a normal Skeleton. The wiki describes her as "a burning Skeleton with charcoal black bones and fire aspects wielding a fiery version of Krom" — a two-hit fire-and-steel package that punishes players who wander in without a fire-resistance plan. Her drop, Hildir's brass chest, and her internal ID, Skeleton_Hildir, both tie her to Hildir content, though the facts here go no further than that naming. This guide covers exactly what the wiki's infobox and combat-log entries document: her stats, her two attacks, her resistance profile, and her loot table, with every gap flagged rather than guessed at.

 

What is Brenna?

 

    Brenna is classified as a Miniboss with Aggressive behavior and is not tameable. She belongs to the Undead faction, found specifically inside Smouldering Tombs, and the wiki also lists her as appearing during the "She's hot on your tail!" event — the source gives no further detail on how that event plays out, so treat the event mechanics themselves as undocumented beyond the name. Her base health at 0-star is 1200. Interestingly, the infobox references separate portrait images for a 1-star and 2-star version of Brenna ("Brenna 1star.png", "Brenna 2star.png"), but no health or damage values are listed for those star levels in this source — so any 1-star/2-star stat numbers are undocumented; don't assume they simply scale the same way regular creatures do.

 

    The wiki also gives an etymology note worth quoting directly: "The Swedish word 'bränna', with similar pronunciation, means 'to burn'" — which lines up with her fire-based kit below.

 

Brenna's attacks and abilities

 

 

    Brenna has two documented attacks:

 

• Sword: a basic slash hitting in a 1.8-meter, 90-degree horizontal arc for 60 Slash damage and 20 Fire damage, usable when a player is within 1.6 meters of her. It's available again every 3 seconds.
• Fire nova: she stabs her sword into the ground, triggering a 3-meter-radius circular explosion for 75 Fire damage. It's available again every 10 seconds once a player is inside its range.

 

    Because both cooldowns are known, the arithmetic on a worst-case, stand-and-tank 30-second window is straightforward: the Sword can land at most floor(30 ÷ 3) = 10 times, for 10 × 60 = 600 Slash and 10 × 20 = 200 Fire. Fire nova can land at most floor(30 ÷ 10) = 3 times, for 3 × 75 = 225 Fire. Added together, that's a theoretical ceiling of 600 Slash and 425 Fire damage in 30 seconds if every single cooldown connects — a worst case, not a realistic one, since both attacks require you to stay in melee range the entire time. The abilities list itself confirms the two cooldowns as "Sword (3s)" and "Fire nova (10s)."

 

Resistances and weaknesses

 

 

    Brenna's damage-type profile is fully documented in her infobox:

 

• Resistant: Pierce.
• Weak: Blunt, Frost.
• Immune: Fire, Poison.

 

    That means arrows and spears from a Pierce-heavy loadout are working against her natural resistance, while a Blunt weapon (mace, hammer, or Frost-imbued weapon/arrow) lines up with both of her listed weaknesses at once. Fire weapons or fire arrows do nothing — she's immune — which also tracks with her being a fire-based Undead herself. No further combat-strategy detail (positioning tips, safe-spot callouts, or a recommended weapon tier) is given in this source, so treat anything beyond the resistance table itself as outside what's documented here.

 

Drops, health, and where to find her

 

 

    Brenna's drop table lists exactly two items:

 

• Hildir's brass chest — 1 guaranteed drop.
• Brenna trophy — 100% drop chance.

 

    No other loot (materials, coins, or crafting components) appears in the drop table field, so this is the complete documented list — don't expect anything beyond the chest and the trophy. Her base health, again, is 1200 at 0-star, with no separate 1-star/2-star totals given.

 

Bring Blunt or Frost damage into the Smouldering Tombs, keep track of the Sword's 3-second and Fire nova's 10-second timers so you're not standing in both at once, and don't bother swapping to fire damage — she's immune. Beyond that, the source documents nothing about safe-spot tactics or a minimum recommended gear tier, so play it cautious on a first attempt.

 

Running your own Valheim server

 

    If you'd rather fight Brenna and the rest of the Black Forest's dungeons alongside friends instead of solo, a dedicated Valheim server keeps the world persistent and lets up to 10 players explore, build, and take on minibosses together without anyone having to stay logged in as host. Setting one up traditionally means fiddling with launch arguments and world files — or you can skip straight to server management and get playing.

Conclusion

 

    Brenna is a compact, fully-statted fire miniboss: 1200 health, a 3-second melee Sword swing dealing 60 Slash and 20 Fire, and a 10-second Fire nova hitting a 3-meter radius for 75 Fire — resistant to Pierce, weak to Blunt and Frost, and immune to Fire and Poison. Her loot is just as tight: one guaranteed Hildir's brass chest and a 100%-chance trophy. What isn't documented — her 1-star/2-star numbers, the mechanics of the "She's hot on your tail!" event, and any deeper combat strategy — is worth keeping in mind before you assume more than the source actually says. Gear up with Blunt or Frost, respect both cooldowns, and the Smouldering Tombs' resident firebrand is a fair fight.
