As an action, you create a wall of animated, jagged, and twisted bones at a point you choose within 36 meters.
If a creature would be surrounded on all sides by the wall (or the wall and another solid surface), that creature can make a Reflex saving throw.
On a successful save, it can use its reaction to move up to its speed so that it is no longer enclosed by the wall.
The wall doesn’t need to be vertical or rest on any firm foundation. The wall blocks line of sight.
The wall is an object made of bones that can be damaged and thus breached. Each panel has 10 Defense and 10 Health per inch of thickness. Reducing a panel to 0 health destroys it and might cause connected panels to collapse at the GM’s discretion.
When the wall appears, each creature within its area must make a Reflex saving throw.
On a failed save, a creature takes 4d6 slashing damage and is grappled for the spell’s duration.
On a successful save, the target takes half as much damage and isn’t grappled.
To break out, the grappled target can use its action to make an Acrobatics or Brawn check (its choice) against your spell save DC.
On a success, the target escapes and is no longer grappled by the bones.
A creature can move through the wall, albeit slowly and painfully. Movement through the wall is at a quarter speed. Furthermore, the first time a creature enters the wall on a turn or ends its turn there, the creature must make a Reflex saving throw as described above.
You can increase the damage by 2d6 for each additional mana or psi expended.
