　Ordinary mold on rations is a familiar annoyance to delvers. Dungeon mold is much worse. You don’t want to be near
it, much less eat it. It’s “just” a passive threat that can’t pursue you or spew gunk, but it carpets things – objects, doors, entire rooms – in ways that complicate an adventurer’s life.

Traits: Clinging; Doesn’t Eat or Drink; Magic Resistance 4; No Legs (Sessile); No Manipulators; Runny Goo; Unkillable 1.

Class: Slime.

Notes: Mold has HP 1 per square yard but indeterminate SM. Area effects affect all mold inside their radius. For Regular spells, pay the energy cost for an SM, look up “Linear Measurement” on p. B550, and square it to find square yards affected; e.g., six times energy cost for SM +5 lets the spell influence 225 square yards of mold. Work backward for known amounts of mold; e.g., a 50-yard corridor with a square two-yard by two-yard cross section has 400 square yards of walls, floor, and ceiling, so if this were blanketed by mold, the goo would count as SM +6 and multiply energy cost by seven. Unaffected by Animal or Plant spells that don’t specifically target slimes. Nonsentient – can’t communicate or negotiate.

Color
Mold is dangerous to touch or walk on. Its color warns of what it will do if disturbed. Roll 3d to choose at random (or roll twice, once for color and once for effect, for weirdly atypical mold).

3-4 – Black: Life-draining. While touching the mold, roll vs. HT every second. Failure costs 1 HP. This injury works like Deathtouch (GURPS Magic, p. 41) and ignores DR.*†‡

5 – Green: Toxic. As Black, but due to poisonous spores, not supernatural drain. Resistant to Poison adds to HT; a sealed outfit, Immunity to Poison, or a Resist Poison spell confers immunity. Lost HP cannot be healed naturally or magically until the subject receives a Neutralize Poison spell, a day of Esoteric Medicine treatment (see Patching Up, Dungeons, p. 13), or a dose of universal antidote (Adventurers, p. 29).*‡§

6 – Blue: Glacial. As Black, but each failed HT roll costs 1 FP due to chills. Winter clothing gives +1 to HT here, a Warmth spell gives +2, arctic clothing gives +3, Temperature Tolerance toward cold adds half its level (round up), and Resist Cold grants immunity. Once FP drop below 0, each FP inflicts 1 HP. Recovering FP and HP lost to cold requires warmth.*†

7 – Violet: Psychedelic. The briefest touch causes it to shed spores that act on contact – and if any of an area’s mold is triggered, it all is. Anyone not in a sealed outfit must make a Fright Check (pp. B360-361) at -10! Abilities, spells, and items that benefit Fright Checks help normally. On long hikes, roll hourly. Failure has its usual effects; new quirks or disadvantages are inevitably goo-related.‡§

8-13 – Brown: Sickening. The briefest touch causes it to shed spores that are harmful on contact – and if any of an area’s mold is triggered, it all is. Anyone without a sealed outfit, Immunity to Disease, or a Resist Disease spell must roll vs. HT-4. Resistant to Disease grants its bonus here. On long hikes, roll hourly. Failure means a malaise that gives -2 to all attribute and skill rolls, and -1 to active defenses, until the victim receives a Cure Disease spell or a day of Esoteric Medicine treatment.‡§

14 – Gray: Putrefying. As Brown, but the disease rots flesh instead. Once the victim is afflicted, he automatically loses 1 HP per hour. This won’t heal until he’s treated with Cure Disease or Esoteric Medicine. At -HP or worse, any failed HT roll to avoid death means the subject liquefies to goo and is beyond resurrection.‡§

15 – Red: Fiery. As Black, but a failed HT roll costs 1 FP due to heat fatigue. Mundane “fireproof” clothing gives +1 to effective HT here, Temperature Tolerance toward heat adds half its level (round up), a Coolness spell gives +2, and Resist Fire grants immunity – but apply encumbrance level as a penalty (e.g., -2 for Medium). Once FP drop below 0, each FP inflicts 1 HP. Recovering FP or HP lost to heat requires water and cool surroundings.*†

16 – Yellow: Corrosive. The briefest touch causes it to shed spores that do damage on contact – and if any of an area’s mold is triggered, it all is. Each second in the area then inflicts 1 point of corrosion damage as Large-Area Injury (p. B400). Keep track of damage and permanently reduce (non-orichalcum) armor or item DR by 1 per 5 points total.

17-18 – White: Exploding. Roll 3d for every second of contact.
On 6 or less, all mold in the vicinity releases spores that explode. Everyone in the area suffers 3d burn ex as Large Area Injury (p. B400). This can happen repeatedly; for long
walks, assess an explosion every 10 seconds.

　* For extended walks over such mold (rather than brief contact), estimate successful HT rolls using Probability of Success (p. B171), rounding in the delver’s favor. For example, someone with Move 5 would need 20 seconds to traverse a 100-yard corridor and thus would face 20 HT rolls; with HT 12, he’d succeed at 74.1% of these, or about 15, and fail at five.
A victim reduced to less than FP/3 or HP/3 should suffer half Move, slowing down and facing more rolls. Rather than calculate this in detail, simply double all harm past the 2/3 mark;
e.g., if a delver has HP 11, injury past 8 HP is doubled, so 20 HP of injury becomes 8 + 12×2 = 32 HP.
　† Supernatural effect, not spores – a cosmic attack reminiscent of Elder Things. Magic Resistance has no effect.
　‡ Dungeon-dwelling monsters may have Resistant or Immunity to this effect.
　§ Rations carried by anyone affected are spoiled unless in sealed containers.

Texture
Mold also comes in a few common textures, none of them pleasant. Roll 1d to choose randomly.

1-2 – Rough: Scratchy bordering on sharp, like rock lichen or coral. Adds +1 per die to damage taken by anyone falling on it, shoved or knocked back into it, or scraped along it in a way that causes damage. This also triggers its contact effect! It’s tough: Increase DR to 2 vs. all attacks.

3-4 – Slippery: Wet and mucus-like. Every second of ground movement over it at Move 2+ requires a DX roll at the speed penalty for that Move (p. B550); e.g., -3 at Move 6. Perfect Balance gives +6. Failure causes a fall; getting up means spending extra time in contact. Delvers can avoid rolls by traveling at Move 1, but that also means longer exposure. Hard to burn: DR rises to 4 vs. fire.

5-6 – Sticky: Tacky and clingy. Reduce Move by 1 if moving in contact with it, which is annoying in combat and guarantees longer exposure. Worse, any contact brings some along! Scraping it off exposes the person (henchman) doing the scraping to 1d seconds of its effects. Not doing so means that in 3d hours, the carrier grows enough mold that every second of movement counts as “contact” for him.

　Mold is as much hazard as monster. It’s usually visible, letting delvers choose their approach: pick another route, eradicate it (see Breaking the Mold, below), levitate over it, or sprint through it. In tight quarters – e.g., roping down a narrow, mold-covered shaft, stooping under a low, moldy ceiling, or squeezing between close, moldy walls – the GM may require a DX roll every turn to avoid contact.

　As mold effects are often assessed every second and may involve DX rolls to avoid contact or slipping, HT rolls to resist, and so on, an extended period of exposure can mean lots of rolling. To make mold interesting rather than annoying, have the adventurers face it either briefly or individually. One option is to situate mobile monsters in the area, forcing the heroes to fight on and around the mold before they’re free to deal with it. Another is to place mold where someone, usually the thief, must crawl alone, so that only one person is rolling. Putting it on something the delvers have to interact with and don’t dare damage – say, an irreplaceable scroll – is classic. And mold is only usually visible; inside a chest or along the seams of a door, contact is brief but inevitable for anyone breaking in.

　Be creative!

Breaking the Mold
　Delvers can wipe out mold, but it’s tough. It’s impervious to poison. It can be scraped away with physical attacks or burned with acid or fire, but on top of its DR 1 (DR 2 if Rough, DR 4 vs. fire if Slippery), it’s Diffuse; impaling or piercing attacks do at most 1 HP, and all others, 2 HP. Only area, cone, or explosion attacks work normally, and most Missile spells and jets don’t qualify – use Concussion, Explosive Fireball, Explosive Lightning, or similar. And thanks to Unkillable 1, mold must be reduced to -10×HP to perish, which means inflicting 11 HP per square yard subject to the above complications.

　Mold-killers who prefer magic should know that dungeon mold evolved in a magical environment. Its HT 16 and Magic Resistance 4 mean Regular spells are at -4 and it resists at 20. Area spells have no penalty but Magic Resistance counts double: resistance is 24. Good luck.
