You cause astral energy to manifest in the physical world, spontaneously forming crystalline structures from your body or the environment.

Crystal Spikes

Class Psion
Name Crystal Formation
Title Crystal Formation
School Metacreativity
Rank 1
Type Assault, Shaping, Utility
Brief Form crystals from your body or the environment to attack, defend, or manipulate your surroundings.

At-will, std, ranged; you form sharp crystal spikes that shoot from your body toward a target within range. Make a ranged attack against the target. On a hit, the target takes medium piercing damage and is slowed (speed halved), Con ends.

By expending 1 Focus when you use this ability, you can create larger spikes that deal heavy piercing damage instead, which cause immobilization (target cannot move), Con ends, replaced with slowed, Con ends.

By expending 1 Focus, you can create a cone 5 of crystal spikes that inflict the same damage and effects to all targets in the area.

Wall of Crystal (rank 2)

At-will, std, ranged, wall 1/level, expends 1 Focus, concentration; a crystalline wall erupts from the ground at a point within range. The wall can be seen through (although it distorts vision slightly), but it blocks line of effect for physical and magical effects. The wall has hardness equal to your Psion level, and HP equal to a heavy damage roll (vulnerable to sonic and bludgeoning damage).

Crystallize (rank 3)

At-will, std, ranged, expends 1 Focus, concentration; you encase a target within range in a thick layer of crystal. The target is unable to take physical actions (Str mitigates; can move at half speed and take physical actions with disadvantage). As long as you concentrate, the effect persists. On the 2nd round, if the target did not mitigate the effect last round, you can expend 1 more Focus to cause the target to become fully crystallized, becoming petrified (Con mitigates to being unable to take physical actions). On the 3rd round or later, you can expend 1 more Focus to make a crystallized target permanently crystal, ending the need for concentration.
