You make terrain feel, look, sound, and smell like some other sort of terrain.

Level: 7	Component Cost: 65 gp
Category: Deception	Market Price: 250 gp
Time: 10 minutes	Key Skill: Arcana
Duration: 24 hours

You can create illusory terrain in the area. You can 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

Creatures believing in the illusion are affected by the hallucinatory terrain as if it was real. A creature can make an Insight check as a minor action to perceive the illusion, but only if it has had some clue to the illusory nature of the terrain 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 hallucinatory terrain take shape can also see though the illusion. The effect has a range of 20 and covers a burst with a size depending on the Arcana check.

Arcana Check Result	Area
9 or lower	Burst 2
10-19	Burst 5
20-29	Burst 10
30-39	Burst 20
40 or higher	Burst 40
