You can create illusory terrain and creatures in the area. You can create blocking terrain or change the appearance of terrain into some other terrain with the same game effect, for example making a marsh appear as deep sand or a solid rock wall appear to be made of translucent crystal. In squares of open terrain, you can add illusory terrain features of these types:

  • Difficult ground
  • Blocking terrain
  • Challenging terrain requiring an Athletics or Acrobatics check of 15 to move into.
  • Cover terrain

You can also create illusory creatures in the area and set them up to act out simple scenes, such as patrolling, camping out, or grazing.

Creatures believing in the illusion are affected by the illusory terrain as if it was real, while illusory creatures are immaterial images only. A creature can make one Insight check as a free action to perceive the illusion, but only if it has had some clue to the illusory nature of the mirage arcana or has interacted with it in some fashion. The DC of the Insight check is 10 + your Arcana skill modifier, and once the check succeeds, the creature can see through the illusion from then on. Anyone who saw the mirage arcana take shape can automatically see though the illusion. The effect has a range of 20 and covers a burst with a size depending on the Arcana check.
