Application of dice in multi-sided dice DND

The dice are d &；; The most important part of D is the iconic prop of Dungeons and Dragons. Everything a character does is influenced by this rule.

The core of D & ampD (Dungeons and Dragons) is a set of mathematical rules, that is, "the law of world operation"-this does not exist for game characters, but it is very important for players: whether an action can be successful, how to judge the effect of the action, and whether the effect is inevitable or random are all determined by this set of mathematical rules. The mathematical framework of D & ampD is based on the random numbers generated by seven (six) dice. The most important thing is 20 dice, which are used in most "success rate tests" (mainly fighting, D&; D is a role-playing game based on combat, and most non-combat parts can be judged by common sense. Whenever a player tries to make an action with a certain probability of failure, he rolls the dice (reflecting the uncertainty of the objective world) and compares the result with the target value (reflecting the determinable ability, technology, environment and other factors). If the final result is equal to or greater than the target value, the operation will be successfully completed. On the other hand, if the result is less than the target value, the operation fails.

This is called "D20 system", which is a rule system with D20 dice as the core. D20 system includes D 12 and D 10 (two, one is 1~ 10 (or 0~9), and the other is 00, 10, 20...90. All the events in the world. The features of D20 system also include HD /HP system based on grade, and linearly increasing character ability.

A person familiar with D&; People in the D system can put almost everything on the D20-for example, the simple action of "pushing the door into the house": if the door is stuck, it will take some efforts to succeed. It can be assumed that the difficulty of pushing the door is 5, and the average person has a great chance of success once. In most cases, they can push directly and occasionally need to try twice; If the door is locked, it can be assumed that the difficulty of knocking it open is 20, and ordinary people may have to try many times, even the run-up can be kicked open; If it is a burglar made of stainless steel, the lock is very strong and must be unlocked with extremely clever technology, then the difficulty will exceed 20, and only a professionally trained locksmith can handle it-this is a typical "D20" process.
