Ongoing damage always lists a die count. When a creature first gains this condition, and at the start of each of their turns, they take the listed damage. Any die that comes up showing a one is dropped from future Ongoing damage rolls. If all dice are dropped, this condition ends.

Ongoing damage cannot be removed with a saving throw. Only dropping all dice will remove this condition. However, a character who is granted a saving throw against the condition may immediately roll the dice for the condition. They do not take any damage, but dice that come up showing a one are still dropped.
