An attacker with Advantage will draw two modifier cards from their deck and use whichever one is better (a).

If one rolling modifier card was drawn, its effect is added to the other card played (b).

If two rolling modifier cards were drawn, continue to draw cards until a rolling modifier is not drawn and then add together all drawn effects (c).

If there is ambiguity about which card drawn is better or worse, use whichever card was drawn first.

Ambiguity can occur when comparing one or more added effects provided by attack modifier cards (e.g., elemental infusions, negative conditions, etc.)

All added effects should be considered to have a positive but undefined numerical value.

Instances of Advantage or Disadvantage don’t stack, and if an attack has instances of both Advantage and Disadvantage, they cancel out each other and the attack is performed normally.

Instances of Advantage and Disadvantage are mostly gained by specific character or monster abilities.
