Miasma is an unstoppable skill, meaning even if you get knocked down the skill will continue to cast, and the max damage output is after 4 seconds it was cast. If the target doesn't die as you cast it will continue to take damage over 4 seconds, as well as being stunned for a bit. This excludes bosses though.

So yet it has a lasting AoE, though it only lasts 4 seconds.
