The Official OSR D&D Skill List

 

Clickbait /OFF

I only want to transcribe here something from another blog, for it is too useful to be lost to the flow of the internets: "The skills you didn't know you had", where the author distills all the different "x in 6" rolls scattered through the OSE book into a "skill list". I am actually using this list as inspiration for MY OWN LIST (to be posted next time), but the source material is so interesting itself that I felt it deserved recognition.  

    Open doors: 2 in 6, modified by strength
    Listening at Doors: 1 in 6 chance of detecting subtle sounds beyond a door, increased for demihumans.
    Searching: If a character is searching in the right location, there is a base 1-in-6 chance of finding a secret door or room trap, increased for some demihumans.
    Avoiding Traps: Every time a character makes an action that could trigger a trap, there is a 2-in-6 chance of the trap being sprung. Lets rephrase this as a 4-in-6 chance to avoid a trap.
    Foraging for herbs, fruits, nuts, etc: can be performed alongside normal movement. The party has a 1-in-6 chance per day of finding enough food for 1d6 human-sized beings.
    Hunting: must be engaged in as the sole activity for a day—no travelling or resting is possible. When hunting, there is a 1-in-6 chance of encountering animals which may be suitable for eating (if they can be caught!). This is in addition to the normal chance of random encounters. A party with a ranger succeeds at foraging with a 2-in-6 chance and finds prey when hunting with a 5-in-6 chance.
    Boarding: If the occupants of one vehicle wish to forcefully board the other vehicle, there is a 2-in-6 chance of being able to successfully manoeuvre the vehicle into a boarding position. The two vehicles may then be clamped together with grappling hooks.
    Surprise Checks: That's a 2-in-6 stealth check right there.
    Tinder box: Used to light fires, including torches. Using a tinder box takes one round. There is a 2-in-6 chance of success per round.
    Dwarven Detect Construction Tricks: As expert miners, dwarves have a 2-in-6 chance of being able to detect new construction, sliding walls, or sloping passages when searching.
    Detect Room Traps: Due to their expertise with construction, dwarves have a 2-in-6 chance of detecting non-magical room traps when searching.
    Halfling's Hiding: In dungeons, a halfling can hide in shadows or behind other forms of cover. The chance of success is 2-in-6. Hiding requires the halfling to be motionless. This enables an additional layer of stealth on top of the base one. If they are still, and behind cover or in shadow, they have an extra chance to be unnoticed to the rest of the party.
    Lore: From 2nd level, a bard has a 2-in-6 chance of knowing lore pertaining to monsters, magic items, or heroes of folk-tale or legend. This ability may be used to identify the nature and powers of magic items.
    Path-Finding: At the start of each day of travel, the referee should roll to determine if the group loses direction. The probability depends on the terrain being traversed:

        Clear, grasslands: 1-in-6.
        Barren lands, hills, mountains, woods: 2-in-6.
        Desert, jungle, swamp: 3-in-6.

Lets restate this one as a navigate skill with a chance depending on the type of terrain. 5-in-6, 4-in-6, or 3-in-6 depending on the difficulty of the terrain. Listed later is the fact it's 4-in-6 to navigate while waterborne. Paths and rivers eliminate this chance. While waterborne however, it requires a specific navigator to help sail, so this is clearly not a skill that all adventurers have. A party with a druid has only a 1-in-6 chance of getting lost in woodlands, so druids score themselves a 5-in-6 in the skill we now have a name for, pathfinding.
    Duergar's Stealth: Underground, duergars have a 3-in-6 chance of moving silently.
    Svirfneblin's Blend into Stone: Svirfneblins have the uncanny ability to go unnoticed when in an environment of natural or carved stone so long as they remain silent and motionless. The chance of success is 4-in-6 in gloomy conditions or 2-in-6 in well-lit conditions.
    Stone Murmurs: Svirfneblins can understand the imper-ceptible grumblings of stone. If a svirf-neblin stands quietly for one turn with their ear pressed against a stone surface, they have a 2-in-6 chance of divining one of the following pieces of information (player’s choice):

        The presence of secret doors in the stone, within 10'.
        The presence of gems or precious met-als, up to 30' beyond the surface.
        The presence of living creatures, up to 30' beyond the surface.
        The presence of bodies of water or open spaces, up to 60' beyond the surface.

* * *

At the end, the author classifies them broadly:

Individual skills are rolled for every person attempting an activity.

    Force isused for forcing open doors through strength.
    Listen is used to hear monsters through doors (breaking their stealth).
    Search isused to find hidden passages and traps.
    Luck is used to not trigger traps by through chance by stepping over a pressure plate instead of on it.
    Enhanced Stealth is used when the party fails its stealth check, but you are a class that has better odds of hiding.
    Use a tinderbox is used to use a tinderbox.

Group skills are performed by the entire group, usually with a single person leading the activity who can provide their experience as a bonus to everyone.

    Forage is used to find food while travelling overland.
    Hunt is used to find food dedicating time to the task.
    Pathfind is used to navigate without a road or river.
    Board is used to position vehicles for boarding.
    Stealth is used to be unnoticed by foes.
