A Curious Assortment of Rules

This is the 32nd in a continuing series of articles, which reedits house rules for Holmes Basic D&D from 40-year-old game club newsletters. Mentions of house rules are in bold text and followed by a [bracketed category designator].

For rules category descriptions and more about the newsletters, see “About the Reedition of Phenster’s.” For an index of articles, see Coming Up in “Pandemonium Society House Rules.”

Phenster’s Pandemonium Society House Rules is a work of fiction. Names, characters, businesses, events, incidents, and newsletters are either products of the author’s imagination or are used in a fictitious manner. Any resemblance to actual persons, living or dead, or actual events is pure coincidence.

Phenster’s “Dungeoneering” article (L’avant garde #74, August 1985) begins with typical subterranean obstacles before diverging into magic items, other equipment, and monsters, in addition to “the Boomtown Rule.” The ring of plate mail, salt’s effect on zombies, and the (non-intelligent) enormous spider come from the first edition (1st through 3rd printings) of Basic D&D (1977), as does the dwarven war hammer.1 This diverse collection of rules is all over the book. I arrange them in Bluebook order.

I find no improvements to make in Phenster’s text describing the monsters. I, therefore, leave the descriptions of the cargolith and the enormous spider as is. I add only a category to each: Cargolith [C] and Enormous Spider [E].

Seeing in the Dark

Phenster doesn’t go into details about Dark Sight [E]. I add that light interferes, as in Holmes, and that a dark-sighted character cannot read in the dark.

Holmes doesn’t specify the later. If we wanted to allow it, we could justify reading in the dark by a different physical process or some innate magic. The advantages of an all dwarf/elf party who could read and see clues in frescoes and wall markings without light, however, might be too tempting and, so, upset any balance of character choices.

With that in mind, many intelligent dungeon dwellers, though they can see in the dark, may still have want of light.

Dark Sight [E]

Monsters, including dwarves and elves but not humans or halflings, can see up to 60 feet in the dark. Any light source interferes with this dark sight. Dark-sighted creatures cannot read without light.

Finding Traps

Regarding traps, Holmes only states that a character springs a trap on a d6 roll of 1 or 2 (10), and a table gives a thief’s chance to remove it beforehand (12). Phenster describes how the Pandemonium Society finds traps without tripping over them.

Find Traps [E]

Players may find a trap by describing how and where the character searches. No dice roll is required. Concealed traps may be discovered only by thieves, who have the same chance to find a trap as they have to remove it.

Force Doors [E]

With a roll of 1 or 2 on a d6, a character may force a stuck or locked door on the first attempt. Strength modifiers are subtracted from the dice roll. A 6 result indicates the door remains intact. Only a character with a higher strength score can open it on a successful roll. On any other result, the door still blocks sight but may be opened without any further dice roll.

Using this rule, we avoid the tedious series of dice rolls and get more impact out of a single throw. Keeping the 6-result failure in combination with the strength modifier allows for more serious consequences for characters of average strength and below.

Normal Weapons

War Hammer [E]

A war hammer does d6 damage (as an ordinary weapon in the Damage Dice by Weapon Class Table) and may be thrown up to 30 feet (as a hand-hurled axe [Holmes, 20]).

Hand-and-a-Half Battle Axe [E]

A battle axe may be wielded in one or two hands. With one hand, it deals d6+1 damage and is treated as a normal weapon with regards to initiative order.2 Two-handed, a battle axe deals d6+2 damage and is treated as a two-handed weapon, that is, it goes last in the round.3 (See the Attack Priority by Weapon Quality Table in “Weapon Damage and Attack Priority.”)

Caltrops [E]

A creature moving through strewn caltrops must slow to half speed to avoid stepping on one. Moving at normal speed, a creature has a 50% chance of taking 1 point of damage. A creature who steps on a caltrop moves at half speed until the damage is healed. One bag of caltrops, costing 1 gp, covers a 100-square-foot area, e.g. 10' × 10'.

Salt [P]

A handful of salt does d8 damage to zombies. To hit, treat the missile weapon as an oil flask (Holmes, 19) with a maximum range of 10 feet. One bag of salt containing 12 handfuls costs 1 gp.

Magic Items

Magic Swords

“Weapons with a plus after them are magical and the user adds the plus to his die roll for a hit… Magical weapons other than swords always add their bonus to both hit probability and to the points of damage scored” (emphasis mine, Holmes, 37).

Holmes carries the magic sword rule forward from OD&D, which states:

“The swords all receive bonuses as far as the probability of hitting an opponent is concerned, but some also gain a damage bonus when they do hit. These swords are those with a +2 or +3 against specific creatures, but not those with a general bonus of +2 or +3” (Monsters & Treasure, 30).

The Pandemonium Society, like most of us at the time, gives swords the same bonus to damage as to hit. The society also uses the glowing sword rule, possibly borrowed from AD&D, wherein “Most swords (and all daggers) of magical nature shed light when drawn from their scabbard” (DMG, 165; see also PHB, 102). Wondering why only 20% of swords would have this property, I add that these swords are made in a certain era or perhaps in a certain land. Thus the [C] Campaign designation.

Magic Sword Bonus Damage [E]

A magic sword gives its magic bonus to the damage roll as well as the attack roll.

Glowing Magic Swords [C]

One out of five magic swords sheds light in a 10-foot diameter when drawn. With rare exceptions, glowing swords were enchanted during the time of the Old Empire.

Dwarven War Hammer [E]

For any character, this is a +3 magic weapon. A dwarf can throw it up to double normal range (60 feet) without a range penalty. If it misses its target, the hammer comes back into the dwarf’s hand. A hit scores an additional d6 damage or 2d6+3. If the target is a giant, the damage is 3d6+3.

Rings of Armor [E]

These magic rings of plate mail, chain mail, and leather armor confer the respective armor’s AC to the wearer with an additional bonus equal to the ring’s magic bonus, +1, +2, or +3. The magic bonus is also applied to saving throws. A character wearing equal or better armor gets only the bonus to saves.

The Boomtown Rule [P]

As adventuring parties haul wealth out of the dungeon and into base town, the local economy suffers from inflation. To model the situation in a simple way, double prices for all goods and services when the player party reaches 4th level of experience. Double all prices again at 8th and 12th levels, and so forth.

This rule should only be used—if at all—in a campaign where most of the found treasure comes into a single town.


1 Zenopus Archives provides an exhaustive list of changes between Holmes’ first and third editions. Note that we have, within the “Holmes edition” of D&D, three editions of the blue booklet, each edition having a number of printings.

2 I take the idea for a one-handed battle axe from Paul Siegel, who suggests fixing a broken concept in B/X by removing the asterisk (which designates a two-handed weapon) from the battle axe. Siegel credits another for the idea in an episode of Wandering DMs. I regret that I can’t find the episode with the mention.

3 Retaining the two-handed battle axe and increasing the damage is my own idea.
