Strahd vs. Pale Horse & Co.
List of Advantages and Disadvantages
Below is a list some internet hero made of all the written advantage and disadvanage triggers in the game. There of course can be others based on circumstance, positioning, and the situation at-hand.
Note also that 1) Adv. and Dis. can only be applied once to any roll, and 2) if there is any amount of disadvantage or advantage at the same time, they cancel out. So if you have 5 things that give advantage, you still only roll 2 dice. Similarly, if you have 5 things that give advantage and 1 that gives disadvantage (or vice versa), there is nothing and you only roll one die as normal.
