  By touching the ground, you curse the land with up to four unnatural hazards, each of CR 6 or less (see Horror Hazards. The hazards must be appropriate to the type of terrain (at the DM’s discretion). Any of the hazards that are rendered safe reset themselves and become dangerous again at each midnight.
  Though this makes the hazards appear frequently, their manifestations are still unpredictable-you can't control when the hazards begin or end, nor where they appear within the cursed terrain. If any hazards are encountered together, the encounter’s effective CR from hazards will be no more than 7 (for instance, two CR 5 hazards could be encountered together).
  Curse terrain spells can be made permanent with a permanency spell. The minimum Caster Level and gp cost are shown on the table below. The spell is still dismissable if made permanent.
