Ability
Any of the six natural traits that represent the basic definition of a player character: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. A player character’s abilities are determined at the beginning of a game by rolling 6-sided dice (d6s). The scores continue to be used throughout the game as a means of determining success or failure of many actions.
Ability check
A 1d20 roll against one of your character’s ability scores (modifiers may be added to or subtracted from the die roll). A result that is equal to or less than your character’s ability score indicates that the attempted action succeeds.
AC
Abbreviation for Armor Class.
Alignment
A factor in defining a player character that reflects his basic attitude toward society and the forces of the universe. Basically there are nine categories demonstrating the character’s relationship to order vs. chaos and good vs. evil. A player character’s alignment is selected by the player when the character is created.
Area of effect (AoE)
The area in which a magical spell or a breath weapon works on any creatures unless they make a saving throw.
Breath Weapon AoE
Various creatures in the AD&D game possess breath weapons, the most memorable being the roaring gout of flame spewed out by a red dragon. These weapons normally affect a cone-shaped area. One point is the dragon’s mouth (obviously) and the breath widens as it extends outward. No attack roll is required for a breath weapon. All characters and creatures within the area of effect must make the appropriate saving throw and suffer the consequences of a successful breath attack.
Creatures with breath weapons cause 1d8 points of damage per Hit Die unless otherwise noted. Thus, an 8 HD dragon would cause 8d8 points of damage with its breath. Fortunately for player characters, the powerful attacks of such creatures have a limited number of uses per day!
Grenade-Like AoE
Most grenade-like missiles are items of opportunity or necessity – flasks of oil, vials of holy water, or beakers of acid, for example. As such, these items are not listed on the equipment tables for range, ROF, and damage. The range each can be thrown varies with the Strength of the character and the weight of the object.
A missile of five pounds or less can be thrown about 30 feet. Short range is 10 feet, medium range is 20 feet, and everything beyond is maximum range. Heavier items have reduced ranges. Just how far they can be thrown is decided by the DM.
Exceptionally heavy items can be thrown only if the character is exceptionally strong – bars/lift gates check. In no case can a character throw an item heavier than his Strength would allow. If it is a solid flask, the DM can rule that a character would have difficulty throwing it as far as a lighter object. If a container hits and does not break, it bounces and rolls to a stop, possibly in the faces of his orcish friends.
Once a container hits, it normally breaks immediately. However, this is not always true. Some missiles, like soft leather flasks or hard pottery, are particularly resistant. If there is some doubt about whether or not a thrown object will break, the DM can require an item saving throw, or he can just see if it shatters or rips, spewing its contents everywhere.
If a missile is off-target, it is important to know where it landed – an errant grenade that missed could present a hazard to the characters, as it falls through a roof or lands on the floor. The process of finding where it lands is known as scatter. First roll 1d10 and consult the Scatter Diagram.
![scattered diagram](https://pathfinder2e.org/rpg/wp-content/uploads/2024/07/scattered-diagram.jpg)
Next determine how far off the mark the throw is. If the throw is at short range, use a 6-sided die. If the range is medium, use a 10-sided die. If thrown to long range, roll 2d10. The number rolled is the number of feet away from the intended target the missile lands.
When the grenade-like missile lands, the DM checks damage on whether a direct hit was obtained and what type of area of effect damage was caused. Damage is often listed as 1d4 damages from direct and splash hits. The Area of Effect of a grenade-like missile covers a 3′ diameter. Any creature in the area of effect will take damage according to the type of hit it received. All creatures within 3′ of the area of effect are subject to splash damage.
Types of Grenade-Like Missiles
Acid damage is particularly grim. Aside from the damage caused by the initial hit, further damage can be inflicted by DM, at a random rate. Acid damage must be healed normally. It is very useful against regenerating creatures such as trolls. Acid is very rare.
Holy water affects undead and creatures from other planes. It has no effect on most other creatures. Holy water causes a damage of 2d4 hp to most undead and can also be used to damage certain evil creatures.
Oil usually affects only materials flammable. Holy oil usually only affects creatures from other planes and can affect creatures of opposing alignments.
Oil causes damage when hit. It is ignited for damage by one of three means: a torch, a burning fuse, or magical fire. It can be used to start large fires. Thrown oil covers a 3′ diameter and causes a fire that burns for 1d6 rounds.
Poison weapon. Most poisons take effect when they come into contact with flesh. A poison only inflicts damage on the target if it drops into the gaping maw of some unsuspecting creature. Contact poisons have normal poison effects on a direct hit.
Table 45: GRENADE-LIKE MISSILE EFFECTS
Type of Missile | Area of Effect | Direct Hit | Splash Damage |
---|---|---|---|
Acid | 1′ diameter | 2-8 hp | 1 hp |
Holy Water | 1′ diameter | 2-7 hp | 2 hp |
Oil (lit) | 3′ diameter | 2-12/1-6 hp | 1-3 hp |
Poison | 1′ diameter | special | – |
Armor Class (abbr. AC)

Critical Hit
A critical hit occurs when a player rolls a natural 20 on a 20-sided die during an attack roll. This signifies an especially successful attack, often resulting in additional damage or other beneficial effects as determined by the Dungeon Master. The exact rules for critical hits can vary, so players should consult their specific campaign rules or the Dungeon Master for details.
Critical Failure
A critical failure, sometimes referred to as a “fumble,” occurs when a player rolls a natural 1 on a 20-sided die during an attack roll. This signifies a particularly poor or unfortunate attack, often resulting in a negative consequence such as dropping a weapon, harming oneself, or other detrimental effects as determined by the Dungeon Master. Like critical hits, the specifics of critical failures can vary by campaign.

Hit Dice
The dice rolled to determine a character’s hit points. Up to a certain level, one or more new Hit Dice are rolled each time a character attains a new class level. A fighter, for example, has only one 10-sided Hit Die (1d10) at 1st level, but when he rises to the 2nd level, the player rolls a second d10, increasing the character’s hit points.
Default monster Hit Dice (HD) is 1d8, so if you see a monster with Hit Dice 3, means that monster has up to 24 hit points, or 3d8.
Hit points
A number representing: 1. how much damage a character can suffer before being killed, determined by Hit Dice. The hit points lost to injury can usually be regained by rest or healing; 2. how much damage a specific attack does, determined by weapon or monster statistics, and subtracted from a player’s total.

Combat involving the use of weapons that shoot missiles or items that can be thrown. Because the combat is not “toe-to-toe,” the rules are slightly different than those for regular combat.
Movement rate
A number used in calculating how far and how fast a character can move in a round. This number is in units of 10 yards per round outdoors, but it represents 10 feet indoors. Thus, an MR of 6 is 60 yards per round in the wilderness, but only 60 feet per round in a dungeon.
MR
Abbreviation for movement rate.

Proficiency
A character’s learned skill not defined by his class but which gives him a greater percentage chance to accomplish a specific type of task during an adventure. Weapon and nonweapon proficiency slots are acquired as the character rises in level, as shown in Table 34. The use of proficiencies in the game is optional.
![table 34](https://pathfinder2e.org/rpg/wp-content/uploads/2024/07/table-34.jpg)
Proficiency check
The roll of a 20-sided die to see if a character succeeds in doing a task by comparing the die roll to the character’s relevant ability score plus or minus any modifiers shown in Table 37 (the modified die roll must be equal to or less than the ability score for the action to succeed).
![table 37](https://pathfinder2e.org/rpg/wp-content/uploads/2024/07/table-37-1024x694.jpg)
A Proficiency Check determines if a character succeeds in performing a specific action, such as climbing or swimming. This check typically involves rolling a 20-sided die (d20) and comparing the result to the character’s relevant ability score (Strength, Dexterity, etc.) modified by any bonuses or penalties associated with their proficiency.
For example, if a character is attempting to climb a slippery surface, they would make a proficiency check using their Climbing skill, adjusted for any difficulty modifiers. The document outlines specific scenarios and the associated checks:
Tightrope Walking:
- Surface Width Modifiers:
- 1 inch or less: -10 penalty
- 2 to 6 inches: -5 penalty
- 7 to 12 inches: no penalty
- More than 1 foot: no check needed
- Other Modifiers:
- Using a balancing rod: reduces penalties by 2
- Winds or vibrations: increases penalties by 2 to 6
- Combat on a Tightrope:
- Attack rolls suffer a -5 penalty
- Proficiency check required each round to maintain balance
Scaling a Wet Wall:
- Relevant Ability: Dexterity
- Modifiers: -4 penalty for the wet surface
- Roll: d20
- Success: Roll is equal to or less than Dexterity – 4
Walking Over a River on a Log:
- Relevant Ability: Dexterity
- Modifiers: -5 penalty for narrow log, additional penalties for wind or vibration
- Roll: d20
- Success: Roll is equal to or less than Dexterity – 5 (plus any additional penalties)
Swimming:
- Characters without proficiency can float but not swim
- Proficient swimmers can move according to the rules in the “Swimming” section (Chapter 14: Time and Movement)
Tracking:
- Non-rangers: -6 penalty to ability scores
- Rangers: no penalty
The specific proficiency and the relevant ability score define the base success rate, and additional modifiers adjust this rate based on circumstances such as surface condition, weather, and equipment used.
Examples:
- Climbing a Wet Wall:
- Use the Climbing proficiency.
- Roll a d20 and compare the result to the character’s Dexterity score plus or minus any modifiers (e.g., wet surface).
- Crossing a Log Over a River:
- Use the Tightrope Walking proficiency.
- Apply the appropriate surface width modifier and roll a d20, comparing the result to the character’s Dexterity score adjusted by the modifier.
Ability Checks as Saving Throws
In some cases, ability checks can replace saving throws to determine if a character avoids danger using one of their abilities. For instance, a Dexterity check might be used to dodge a falling rock .
These proficiency checks and ability checks provide a flexible system for resolving a wide range of actions and challenges in AD&D 2nd Edition.
