Morass Diabolus sprays venom on several enemies, the number of which is equal to the number of classes covered all surviving enemy heroes. The venom deals damage to the target and their nearby enemies, also inflicting Mortal Poison on them, while reducing their Attack Rating by 20% for 12 seconds. This effect can be stacked up to 3 times.
Morass Diabolus is surrounded by Marshy Scourge. Enemies within the Marshy Scourge have their Haste reduced by 80 points, and they suffer from a Depraved state after moving a certain distance or dwelling in the Marshy Scourge for a period of time. A Depraved state renders them immobile for 3 seconds. The higher the Mortal Poison level, the more likely its target is to fall into a Depraved state.
Morass Diabolus chants continuously, widening the range of Marshy Scourge and pulling enemies within it towards its center. While chanting, if Morass Diabolus takes damage 30 times without being protected by a Seedy Shield, its chanting is interrupted and it becomes weakened temporarily, with its received damage increased by 50%. When the chanting ends, it deals damage to enemies in the center of Marshy Scourge and knocks them back.
Every 5 seconds or whenever an enemy falls into a Depraved state, Morass Diabolus grants itself 1 stack of Seedy Shield. Each stack of Seedy Shield reduces the damage it receives and its health loss by 20%. This effect can be stacked up to 4 times. A Seedy Shield can be dispelled, and within 3 seconds after it is dispelled, it cannot be regained.
