As two actions, you create a wall of tough, pliable, tangled brush bristling with needle-sharp thorns at a point within 20 meters for the duration. The wall can have any shape you desire, though it can’t occupy the same space as a creature or object. The wall doesn’t need to be vertical or rest on any firm foundation.
If the wall cuts through a creature’s space when it appears, the creature is pushed to one side of the wall (your choice). 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 is an object made of plants that blocks line of sight. A creature can move through the wall, albeit slowly and painfully. A creature must spend 3 meters of movement for every meter it moves through the wall. The wall can be damaged and thus breached. Each panel has 10 Defense, 1 Soak, and 10 Health per centimeter of thickness. Reducing a panel to 0 health destroys it and might cause connected panels to collapse at the GM’s discretion.
You can choose to cast this spell without thorns to bridge a chasm or create a ramp. If you create a span greater than 4 meters in length, you must halve the size of each panel to create supports. You can crudely shape the wall with or without thorns to create crenellations, battlements, and so on.
When a creature enters the wall’s area for the first time on a turn or starts its turn there, the creature must make a Reflex saving throw.
On a failed save, a creature takes 5d8 piercing damage, or half as much damage on a successful save.
If you maintain your concentration on this spell for its whole duration, the wall becomes permanent and can’t be dispelled. Otherwise, the wall disappears when the spell ends.
You can increase the damage by 2d8 for each additional mana or psi expended.
