Athas’s sun burns with peculiar intensity in areas where magic has defiled a copious amount of plant life. This severe heat can sicken creatures.
Effect: A creature that ends its turn in a square of sickening heat is weakened until the end of its next turn.
Usage: Sickening heat defiled terrain is particularly debilitating to strikers and others who specialize in high-damage output. A monster with a power that slides and then immobilizes enemies is particularly effective in an area of sickening heat.
