It's just you. :>

Actually, the few times I've encountered Brown Mold I was lucky enough to have Ray Of Frost handy.


Brown... it just had to be brown mold.

The last few times I've seen it people tried to burn it. Yeah...

I fear for the day when a Remorhaz and a patch of brown mold meet.
Heat ability and Cold immunity make for the perfect carrier creature.

You know... Many undead are outright immune to cold. Used to be whole builds around making an undead army with a caster who uses cold damage. Uttercold we called it. Not that I'd ever suggest you do something that crazy.

Our first level party in the AP Age of Wurms has enountered this, and failed our dungeoneering roll. Nearly killed the first two people in our marching order. Luckly the tiefling fighter survived the 10 pts of cold and grabbed the dropped bard and backed away. We're avoiding the corridor for now.

Burning Skeletons exist.

Yes they have Cold Vulnerability but 3d6*1.5 is jack diddly when it runs into the fact that they're immune to nonlethal.

Oh yeah, they're immune to non lethal... That too!

Burning Skeletons sound like they'd give you more mold than you want though. I don't think much is fashionable with brown mold, but maybe that's a personal bias.

I once created a few very Moldy Mummies :D

I used some of this in a dungeon not long ago. It will be a long time before I do so again. This quickly became one of the most potent weapons in the party's arsenal.

Brown Mold, you say?

I like the two main qualities:
1) Fire brought within 5 feet of brown mold causes the mold to instantly double in size.
2) The temperature is always cold in a 30-foot radius around it.

I am so going to destroy the elemental plane of fire with a small patch, making it a temperate paradise (or rather cold paradise) with my Way of the Wicked character (Note to self: Write an extreme hatred towards the elemental plane of fire into character backstory...)

I once wiped out half a party with this stuff. Barrel full of flammable liquid (I forget what, exactly) in one corner of the room, brown mold in a single square next to it. Failed to identify the hazard. Fireball.


While running the Shackled City campaign, the party burned down an inn which happened to be using a patch of brown mold to create a refrigerated room. I decided to relent and not have the mold expand to cover several square miles of jungle surrounding the inn.

Don't mess with CR2 hazards.

Had a party wipe from Purple Moss before. No one left that game happy.

... What happens if an ifrit character falls in brown mold? >_> They are on fire at all times.


I give you a CR 1 swarm immune to weapon damage.

This set the tone really well for my Shattered Star group.

Mythic Brown Mold is awesome.

Tell me about it, my group is doing Shattered star now, we up to book three, but those swarms man, we lost the druid pet and a party member to those things when we were low level.

Same here in book one, almost a wipeout to the swarm in the lower level, took three of the party down to below zero as they fled in panic.

I think anytime I've encountered it as a player or used it as a GM it has been noticed, identified, and either avoided or destroyed.


I had brown mold in a game once but I must've done it wrong. I had it in the same squares as a scything blade trap so anyone trying to disarm the trap was taking damage. Nearby was a side entry to a dragon's lair so kobolds could worship it. Anyway, there were some kobolds harrying the party, the trap, and the brown mold... but the party was 5th level. They basically whomped the entire encounter, took some minor damage and shrugged. After the fact they successfully identified the substance and ray of frosted it out of existence; the barbarian then activated the trap again later and sundered one of the blades so they could get to the dragon...

I suppose I should use it only at low levels.


If your party fails to stop the boss taking over your world and you're the only survivor... Add 1 jar to 1 active volcano and plane shift !

If you don't happen to be prepared for it in your concept then it's really rough. I kept emphasizing the well-rounded adventurer to them during character creation. Oh well... :)


My GM recently used this as a trap against our level 2 party.

Here's how it played out.

GM: Roll Perception.
Me: 25
GM: You notice that the floor of the room seems to be covered in a mold of some description.
Me: My druid uses Knowledge Nature to see if he is familiar with the mold.
GM: Roll it.
Me: 23
GM: Your druid recognises it as brown mold, he knows that its grows from being exposed to fire and that it is destroyed by cold.
Me: I cast Frost Touch and touch the mold
GM: Mold deals 18 points of nonlethal damage.
Me: I deal 8 points of non lethal cold damage to the mold.
GM: the Brown Mold is destroyed by the attack.

Was very lucky though. My druid is the only member of the party with any cold based damage spells so he was the only one who could stop it. If I hadnt rolled so well on the Perception and Nature Rolls it could have been a different story.

In the future, the world will know the power of the four elements: Air, Earth, Water, and Brown Mold.

I like Brown Mold, Green Slime, et. al. because it brings back the old AD&D feeling when encountered by low level characters.

It only takes one party wipe from a hazard to give the entire campaign a sense of peril throughout.


If brown Mold exists then the players will use it. And then they will abuse it. If you think that it's scary against the P.C's you have not seen anything yet. This stuff is a kingdom destroyer.

It's true that players have an uncanny knack for wrecking your campaigns—a knack equaled only by their skill in wrecking their own party.

In other words, how do these adventurers plan to use the brown mold without it backfiring horribly?

"Sir, the adventurers are threatening to infect the entire city if you don't declare one of them the Super Great Awesome Arch-Emperor. They can't seem to agree on which one, but..."

"Ugh. Alright, call in our frost giant enemies and negotiate a truce. Have them send in the remorhaz."

The PCs are toying with powerful forces here. They want to wield it as a weapon? That's not gonna end well.

The Exchange

I'm pretty fond of "infestations," including brown mold. PCs who realize what they're up against can demolish the stuff pretty readily, but novices (or groups with no Dungoneering knowledge) often suffer.

One dirty trick I've never used, by the way, is a room holding both brown mold and basidironds.

Dragon #288 and Dragon #308 had some fun creature combos that would still be valid in Pathfinder. Ghouls and yellow mold was one of the combinations that stuck in my head.

But everything changed... when the Brown Mold nation attacked.


Suddenly the "Ray of Frost" arcane cantrip looks much more worth having handy. The description of the Brown Mold states that cold damage instantly destroys it, so presumably the 1d3 from the level 0 spell is adequate. (I'd dismissed the spell as giving too trivial damage, but I do note that it's meagre damage offers no saving throw; I wouldn't want to use a cantrip slot JUST in case of Brown Mold, but it could be tempting for characters who are too low level to have any other way of dealing cold damage).

I think the next-lowest-level way to deal with the mold is through the level 2 Druid Spell "Chill Metal". A piece of metal could be thrown into the mold, and then chilled by the Druid. "Unattended, nonmagical metal gets no saving throw".

Molds in general are scary to me. Especially the ones that have such a high DC they cannot be identified for many levels in the future...

I wish more natural hazzards like this were incorporated into the environment in campaigns outside of adventure paths. Dat flava


Interestingly slimes are a fairly common threat in various sci fi settings. I recall one I red recently where there was this red stuff that a survey ship encountered on an asteroid and got covered. When the retrieval ships arrived they found a round red ball in place of a ship that tried to infect them (reaching out and covering the ship that got close, they burnt it off with the other ships engines). Being humans and thus lacking in common sense they took samples back to their lunar colony where it got loose. End of the story it was slowly spreading out from the lunar base and they were concerned if it reached the others they'd loose access to the outer systems as it was a necessary stop over point.

Your Uttercold link went to a page with a WOTC Cease and Desist order.

I'm sure he'll go back in time a year and 7 months and fix that right up for you.


Don't want to spend a cantrip slot on Ray of Frost? Fine. Make a scroll. 4 shots of Ray of Frost on a scroll costs 25 GP and in a pinch either destroys Brown Mold or delivers an extra 1d3 damage to your enemies.


Mummy with brown mold


1 person marked this as a favorite.

Ya, Brown Mold... We ran into this with a Lvl 6-7 pathfinder society party.

We failed our rolls to identify it even though we spotted it. So ya, sarcophagus giving off an aura of cold and is covered in mold? We applied typical logic and tried to kill it with fire, you know elemental 101: if it is hot freeze it, if it is cold burn it.

Anyhow, three mummies crawl out and attack us while covered in the stuff. So ya, meleeing mummies as they give off the cold aura doing 3d6 damage a round. We knew mummies were vulnerable to fire, so after a round or two the mold is everywhere! No one had the metagame knowledge of what it was either, so no discrete hints that maybe all this fire we are throwing around might be making things worse...

Oh, and then we had to run through the hallway full of the stuff, because we still had no idea how to get rid of it, and into the room that we thought had the last encounter...

Now every character buys Liquid Ice at lvl 1, because never again...


I'm surprised no-one suggested the horror of mixing the brown and purple mold... in the same encounter/room... say someone fails to identify one and succeeds at identifying and tries to destroy the other... it could definitely put you to sleep in the cold.


My players have recently been encountering the brown mold, but this happens to be the one campaign where no one is using fire based anything.....

So they take a little bit of cold damage while beating the bad guy, then they move on like it was no big deal.

Silver Crusade

Hmmm, I am thinking Liquid Ice?


"Fire brought within 5 feet of brown mold causes the mold to instantly double in size."
How often can it do this? If I summon a huge fire elemental next to it, does it double in size once a round until the elemental dies, or what?

I had a White Dragon boss in a campaign that had brown mold patches hidden all around his lair. It couldn't hurt him, would damage those seeking to invade his lair, and the typical area effect fire spells one would use against the Fire-Vulnerable white dragon would cause the patches of mold to expand and become more dangerous.

Unfortunately, things like skeletons and trolls are much more likely to be encountered than brown mold, so acid splash is pretty much always a better slot choice. Plus it has no spell resistance.

If you left a slot open though, you can always prep it in the field, since the mold won't chase you as long as you're not being dumb!

We ended up surviving that encounter, and managed to bring some back to our HQ to make a cold storage for food.

Brown mold feeds on warmth, drawing heat from anything around it. It normally comes in patches 5 feet in diameter, and the temperature is always cold in a 30-foot radius around it. Living creatures within 5 feet of it take 3d6 points of nonlethal cold damage. Fire brought within 5 feet of brown mold causes the mold to instantly double in size. Cold damage, such as from a cone of cold, instantly destroys it.

I don't think this stuff is as potent as you guys seem to think.

I believe the intent of this CR 2 hazard, was that the entire patch doesn't double in size so much as the nearby 5-foot radius patches double in size. Overlapping patches have no effect.

For example, a patch with an 80-foot radius wouldn't become a patch with a 160-foot radius when fire gets close. Only a smaller corner of it would grow towards the flame (in 10-foot radius increments). However, if there are multiple 10-foot radius sections nearby, they could all quickly double in size.

In other words, the expansion--being based off the original patch's size--would be linear, not exponential.

At least that's what I believe the intent to be. Any other interpretation just proves too disruptive (and this one still comes close).


Double also doesn't necessarily mean radius, but could mean area. As in 5x5 becomes 5x10, 5x10 becomes 10x10, becomes 10x20, at most, etc., even if constantly all exposed to flame.
