Level 14 DiseaseFilth Plague

Infused with the toxic filth of the Demon Wastes, this disease turns the target’s internal organs to a bloody froth.

Stage 0: The target recovers from the disease.
Stage 1: Initial Effect: The target loses one healing surge.
Stage 2: The target takes a -2 penalty to attack rolls and a -2 penalty to its speed.
Stage 3: Final State: The target takes a -4 penalty to attack rolls, is slowed, and takes 5 extra damage from all damage-dealing attacks. The target loses all healing surges and cannot regain hit points. If subsequently reduced to 0 hit points, the target is dead and bursts, with all creatures within 5 squares of the target contracting filth plague (no attack roll).
Check: At the end of each extended rest, the target makes an Endurance check if it is at stage 1 or 2.
23 or lower: The stage of the disease increases by one.
24-28: No Change
29 or higher: The stage of the disease decreases by one.
