Level 9 DiseaseMeenlock Corruption

A meenlock’s attack can crush a foe’s mind, turning it into a puppet under the meenlock’s control. Even if the attack is shaken off, the target feels the lingering effect of the psychic corruption these creatures inflict.

Stage 0: The target recovers from the disease.
Stage 1: Initial Effect: The target takes a -4 penalty to Will.
Stage 2: The target grants combat advantage.
Stage 3: Final State: Unless prevented from doing so, the target moves toward the lair of the meenlocks that infected it. Treat the target as dominated by meenlocks until the disease is cured.

14 or lower: The stage of the disease increases by one.
15-19: No Change
20 or higher: The stage of the disease decreases by one.
