| - ThAC0 (принятое сокращение от «To Hit Armor Class 0» — англ. "поразить класс защиты 0") — параметр атаки, используемый в боевой системе Advanced Dungeons & Dragons 2. Этот параметр определяется как результат броска 20-гранного кубика, минимально необходимый данному персонажу или монстру, чтобы пробить класс защиты, равный 0. Минимальный результат d20, необходимый для пробития других значений класса защиты, вычисляется путём вычитания значения класса защиты из ThAC0. Чем ниже значение ThAC0, тем больше вероятность успешной атаки. Например, воин 7 уровня имел ThAC0 14, то есть для попадания по AC 0 ему нужно было на 1d20 выбросить 14 или больше. Для попадания, скажем, по AC 6 (орк в кольчуге) тому же воину нужно выбросить 8 или больше (8=14-6). Операция вычитания вообще выполняется в уме с бо́льшим трудом, чем сложения, а в реальной игре присутствовал бы ещё и целый ряд модификаторов к AC, ряд модификаторов к ThAC0 и ряд модификаторов к собственно результату броска, что делало всю механику атаки чересчур перегруженной. Значение ThAC0 увеличивается с уровнем персонажа, по-разному у разных классов (с 1-го по 20-й уровень это значение растёт у воина от 20 до 1, у жреца от 20 до 8, у плута от 20 до 11 и у волшебника от 20 до 14). За каждый новый уровень у воина ThAC0 уменьшается на единицу, у жреца — на 2 единицы за три уровня, у плута — на 1 за два уровня и у волшебника — на 1 за три новых уровня. Вне зависимости от того, какой результат броска нужен персонажу, чтобы нанести результативный удар, 20 на кубике d20 всегда считается результативным ударом, а 1 на d20 — всегда промахом. Система ThAC0 заменила боевые таблицы из первой редакции AD&D и была в свою очередь заменена в D&D 3+ на вычисление результата атаки как «d20 плюс бонусы атаки против значения класса защиты».

- THAC0 (IPA: /ˈθækoʊ/) is an acronym constructed from the phrase "To Hit Armor Class 0" which comes from the role-playing game Dungeons & Dragons. THAC0 was first introduced in the Dungeon Master's Guide of the 1st edition of Advanced Dungeon & Dragons(1979) as a convenient way to calculate the entries of the combat tables that were used to determine the success of a physical attack. In the 2nd edition of Advanced Dungeons & Dragons THAC0 replaced the combat tables completely and therefore most people associate THAC0 closely with this edition of the AD&D game. THAC0 is a measure of a character's or monster's ability to successfully attack an opponent in physical combat. Each creature has an armor class that determines how hard it is to hit that creature, with lower numbers representing higher difficulty. For example, a normal, unarmored human has an armor class of 10 while a heavily armored fighter might have an armor class of 1 or 0. The success of a character's or monster's attack is determined by rolling a 20-sided die. If the number obtained equals or exceeds the attacker's THAC0, the attacker has successfully hit a target with armor class 0. If the target has an armor class different from zero, the target's armor class is subtracted from the attacker's THAC0, and that number is what the attacker's roll must equal or exceed. A simple formula for quickly calculating the success or failure of an attack roll using THAC0 is: THAC0 - (roll on a d20) = AC Hit. For example, if the attacker has a THAC0 of 17 and rolls a 15 on his or her To Hit roll, the attacker has succeeded in hitting if the target's armor class is 2 or higher (2 or worse). High THAC0s signify that an attacker is poor at hitting targets, while low THAC0s indicate the attacker can hit targets with ease. There is nothing particularly significant about an armor class of 0 other than the fact that it simplifies calculations. The idea that a creature is harder to hit when its armor class goes down was felt by some players to be counterintuitive. Furthermore it produces mathematical inconsistencies in the game system with magical armours as a beneficial magical modifier is always denoted with a "+" although it has actually to be subtracted from the AC. For example an ordinary chain mail armour provides a character with an AC of 5 whereas a magically enhanced version with a +3 modifier would improve the AC to 2 and not 8 as one might expect. In the 3rd edition of D&D (2000), the armor class system was changed and THAC0 is no longer used in the following D&D editions. THAC0 is still sometimes unofficially used with the HackMaster RPG, which is derived from 1st and 2nd edition AD&D. While some players mourned the loss of the THAC0 system in the change to 3rd Edition D&D, many invited the new system, which replaces THAC0 with a bonus to the attack roll called base attack bonus (in short BAB) and features an armor class rating that increases as it becomes harder to hit a creature. However, mathematically both systems are equivalent and the THAC0 and AC values of AD&D can be easily transformed to the AC and base attack bonus values of the later edition.
* BAB = 20 - THAC0
* THAC0 = 20 - BAB
* 3rd Edition Armor Class = 20 - 2nd Edition Armor Class
* 2nd Edition Armor Class = 20 - 3rd Edition Armor Class
- THAC0 (/ˈθækoʊ/, thack-oh) is an abbreviation for To Hit Armor Class Zero (0). To calculate if a hit succeeds you would take the AC of the target and subtract it from the attacker's THAC0, then roll a 20-sided die; if the die rolls equal to or higher than the calculated number, the attack hits. That is, THAC0 − AC = roll needed to hit. This means that a good character will try to get both their AC and THAC0 values as low as possible! Example: If the player has an AC of 5 and THAC0 of 10, and the enemy has an AC of 10 and THAC0 of 18: Chance of player hitting the enemy: 10 - 10 = 0. Although it may seem that with these numbers it is impossible to miss, a roll is still required as a roll of a natural 1 is ALWAYS considered a miss. Chance of enemy hitting the player: 18 - 5 = 13. this is a difficult target to hit, since a roll of 13 or above is required. Another example: If a target has an AC of −3 and the attacker has a THAC0 of 8, 8 − (−3) = 11. The attacker must roll 11 or greater to hit. Fighter classes have the best THAC0 progression and spell users have the worst. Lower THAC0 is better, since you have to roll equal to or higher than the to-hit number. For more on THAC0, consult the AD&D 1st/2nd edition DM Guide(s). A rough guide to convert THAC0 and AC to 3.0 and higher is to subtract the number from 20. so 20-THAC0= Attack bonus, 20-AC= (New)AC. using the Above examples the Player now has AC 15 and attack bonus of +10, and the enemy has AC 10 and attack bonus of +2
