At the start of your turn, apply 3 Poison to ALL enemies.
Cost: 1 Energy, applies 2 Poison, 3 upgraded, to every enemy at the start of each of your turns, beginning the turn after you play it.
Poison: deals its full stack at the start of the enemy's turn, then drops by 1, so the fumes outpace the decay.
Growth: an enemy takes 2, then 3, then 4 and so on, or 3, 5, 7 upgraded.
Count: the Poison applies to each enemy separately, so a three-enemy fight counts as three applications for Outbreak.
When to take Noxious Fumes
The core of a Poison deck, worth taking in Act 1 and playing turn 1, since it is strongest against groups and long elite fights. Upgrade early, since it nearly doubles the damage curve.
