Baldur's Gate 3: Advantage & disadvantage
One of the main features of the 5th Edition is the advantage and disadvantage system. Depending on the circumstances, this will apply to an attack, stat, or saving throw. When this is the case, you will roll 2 d20, and use the highest score if you have an advantage, or on the contrary, use the lowest roll if you have a disadvantage.
- Example: You roll 2 dice and get a 4 and a 17. In case of advantage you use 17, in case of disadvantage you use 4.
- If you try to use your force on a spell, you'll have a disadvantage. But If you use your strength to keep an enemy on the ground, you'll have an advantage.
In situations with several advantages, or several disadvantages, you always roll 2 dice only. If there is both an advantage and a disadvantage, they cancel each other out.
You could say that your chances of success are approximately doubled in case of an advantage, and approximately halved in case of a disadvantage. You must take this into account and try to gain the advantage whenever possible, for example by having the advantage of the terrain and controlling the situation, rather than by heroically (and stupidly) rushing into an ambush with traps.
