Stacking Advantage and Disadvantage

• When a roll is made with a source of advantage and disadvantage at the same time, it becomes a flat roll instead.
• If there are more sources of advantage than disadvantage, the roll is made at advantage. Conversely, if there are more sources of disadvantage than advantage, the roll is made at disadvantage
• Take the difference in number of advantage sources versus disadvantage sources on a roll to determine whether any advantage or disadvantage will stack with itself beyond regular advantage or disadvantage (see Situational Bonuses/Demerits below).

Situational Bonuses/Demerits:

• If the player makes an ability check, attack roll, or saving throw under beneficial circumstances, uses quick thinking/clever planning to their advantage, or otherwise makes a decision the DM believes would assist in making their check, the DM may give the player one or more situational bonuses on the roll. A player may roll a d4 and add it to the total result of the check for each bonus on the roll.
• The DM can also give situational demerits to these same types of rolls if it is determined they are being made under detrimental circumstances. A player rolls a d4 and subtracts the total from their check for each demerit on the roll.
• A situational bonus or demerit is given when multiple sources of advantage or disadvantage are stacking on each other.
  • Examples:
    • If the player made a clever plan, and also has backstory reasons they should be able to make this specific check, these sources can stack to add 2d4 to the check.
    • If a player gives the help action to another player to hit a creature which is restrained, these sources of advantage could stack, providing a single situational bonus alongside the advantage.
    • However, even if another source of advantage is added to the previous example (say the target is having a truly awful day and is also paralyzed while this is happening), it would not add another situational bonus. The roll would still just be made at advantage +1d4.
    • If the attacking player in the previous example gained a situational bonus from another, non-advantage related source (perhaps the DM wanted to give a bonus to the attacking player because this fight is relevant to their story, and they delivered a heartfelt speech before the attack), the roll could become one made at advantage +2d4.

Help Action

• A creature may only give another creature the help action on a skill check if the creature providing help is proficient in that skill.
