In Vallistra, Hunters will often face adversity and will require taking risks in order to succeed. The main types of dice used in Vallistra are the 6-sided die known as the d6, the 10-sided die known as the d10 and the 10-sided die with tens labelled named the decader. A large number of d6s are used, up to 24 may be rolled at a single time, while only a single d10 and decader are required. The d6s are collectively known as the Dice Pool while the d10 and decader (collectively known as the d100) are rolled together to obtain a result from 1-100. D6s are used to resolve whether a success or failure occurs, while the d100 is used to resolve situations where a finer degree of chance is involved.
When the d6 is rolled, it can show 6 different numbers, but there are only 2 meaningful results. Whichever side the number lands on top is the number that determines the result. The two results are successes and failures. Failures do not necessarily mean that a bad thing has happened, but rather it is the absence of a good thing. Successes indicate that a degree of success has occurred. Multiple successes added up creates a larger and better success.
Rolling a 1 on the d6 is known as a success. Rolling a 6 on the d6 is known as an explosive success. When an explosive success is rolled, 1 success is counted, but the die can be rerolled again. If the die lands on a 6 again, then the die can be rerolled. This can continue infinitely. Rolling a 2,3,4,5 is known as a failure. When rolling dice, failures are not counted, only successes.
For example, Emily currently has a dice pool of 5 dice. She rolls all 5 and obtains a result of 1, 6, 2, 4, and 6. Because she rolled a 1 and two 6s, she counts 3 successes. Since she rolled 2 sixes, she can reroll those two dice again. This time, she obtains a result of 1 and 6. She counts 2 successes and tallies her total to 5 successes. She can reroll on die, this time obtaining a result of 4. This is a failure. She has a total of 5 successes (3+2+0).
When the decader and d10 are rolled, it is known as rolling the d100, or Chance Die. In some occasions, a particular result occurs depending on the number rolled. For a Chance Die to be successful, it must roll above a certain target number. For example, if the target number was 51 and the d100 lands on 66 [60, 6], then it is successful. If it instead landed on a 21 [20, 1] then it would be a failure.
Some results on the d100 are more difficult to interpret. Usually, the two dice are added together. In the occasion that the decader rolls a 00, then a result of 1-9 on the d10 will mean that the result total is 01 to 09. However, if the decader rolls a 00 and the d10 rolls a 0 then the result is actually 100 [00, 0]. There are no speciality effects for landing on particular numbers on a d100 unlike the d6s.
D6s and D100s are rolled when there is a chance of success and a chance of failure. These can occur in almost any situation that a Hunter faces. When playing Vallistra, there are different phases that can occur. Phases are settings in which particular events are occurring. The different phases of gameplay will be covered in this section.
