CHASE has boons and flaws that affect the numerical outcome of dice rolls, some being situational and others permanent.
#'d bonuses (+1, -3, etc) are permanent and come from passives or items. They usually affect stats, and are one of the few bonuses at affect Attack Rolls (either directly or indirectly).
Bonus and Penalty Dice are a stacking dice that start at 1 stage, usually a d4, and build up with each similar bonus. d4 becomes d6, then d8, then d10, then d12. After d12, the stack begins again with the previous dice, becoming d12+d4, then d12+d6, so on and so forth. They are the most common kind of bonus due to being both constant and situationally given.
Advantage and Disadvantage allows you to reroll d12s and d20s and take the higher (or lower, respectively) result. This includes bonus/penalty dice as well. They are exclusively situational, but easy to calculate. Multiple instances do not stack, so you only get Advantage/Disadvantage on a roll once even if gaining it from multiple sources.
Bonuses and Penalties do not subtract or cancel each other out, except for Advantage/Disadvantage.
Throughout the game, you will be offered, and have to calculate, special ways of rolling the dice that either help or hinder the dice's outcomes. These are Bonuses and Penalties.
There are three major kind of Bonus/Penalty Types.
#'d/Numerical, Bonus/Penalty Dice, and Advantage/Disadvantage.
#'d/Numerical Bonuses/Penalties |
Numbered bonus are passive, often permanent effects that are given by effects that last for lengthy periods of times, with the shortest amount being 24 hours, or after a Long Rest. They often come from items, consumables that grant permanent boons, feats, and system based gains/subtractions (such as
Attribute Boosts and Attribute Flaws).
In other games, these bonuses are seperated and limited by Type, but that is not the case in CHASE, as they stack as much as they need. Offsetting this, these bonuses are far more rare than Bonus/Penalty Dice and Advantage/Disadvantage.
Bonus Dice and Penalty Dice are both dice-based bonuses that technically scale infinitely. When you are given a Bonus or Penalty Dice, you have an additional 1d4 to roll, adding the result (for Bonus Dice) or Subtracting the result (for Penalty Dice).
Bonus and Penalty Dice will always be situationally applied, but constant. They will also be applied to situations involving exploration and the end factors of combat (such as skill checks, damage, healing, etc), and will specify between each bonus/penalty (e.g, adding damage via bonus dice to a
Flametongue Sword will give give a bonus dice for piercing, slashing or fire, but if you gain a bonus dice specifically for fire damage, it can only be added to the attack's fire).
When another effect gives you a Bonus Dice or Penalty Dice, you increase the dice’s size by 1 step, or upgrade the dice to the next biggest size. 1d4 becomes 1d6, 1d6 becomes 1d8, 1d8 becomes 1d10, and 1d10 becomes 1d12 (or about 5 steps per d12). When you reach 1d12 and the dice increase by another step, you add another 1d4 and start all over with that dice (to 1d12+1d4, 1d12+1d6, so on and so forth).
An
Optional Rule of this exists, if everyone at your table would rather not rely on the randomness of dice.
Advantage and Disadvantage is simply rolling a d20 or d12, and taking the higher result (if it is Advantage) or the lower result (if it is disadvantage) of the two rolls.
You can gain Advantage and Disadvantage from multiple sources, but you only gain the benefit of the first from each.
Interaction with each other |
All bonuses and penalties stack with their given type. For similar types of opposing benefits/flaws, you use both, rather than cancel them out.
On paper, Bonuses and Penalties appear to cancel each other out anyway
, but they do not do so mechanically. E.g, if you have a +5, and gain a -3, your total bonus may be +2 for that given stat/roll, but you still have the +5 and -3.
The same goes for if it was 5 steps of bonus dice (1d12) and 3 steps of penalty dice (-1d8). You would roll both 1d12 and 1d8, and use the result, rather than roll a 1d4.
Advantage and Disadvantage affect a roll once, therefore negating the ability to take the highest/lowest result, but you still have either type of bonus/penalty, which affects certain feat/ures or rules (such as the Rogue's Sneak Attack).
