Psychic sword

A psychic sword was often a psionic longsword that was inspired by the githyanki silver swords. It replaced magic with psionics however.

Description
The blade was dark and inert until it was wielded by a being of intelligence. When that occurred, the psionic circuitry in the sword would glow.

Powers
Depending on the user's intelligence, the powers of a psychic sword differed. It was likely that different blades provided different powers however, the powers were cumulative:
 * Any blade of this kind acted like a mundane sword to a user who was able to pick up new ideas quickly and learn easily.
 * Such a blade was barely usable to a user who could solve most problems with little effort. It only was easier to hit the wielder's target.
 * A wielder of the blade who was fairly intelligent would see that it was even easier to hit one's target, and that the cut bit deeper. Beyond this while drawn, the sword granted the user non-detection from both magical and psionic means.
 * A genius who wielded the blade would find it even easier to hit their opponent, while cuts became even deeper. The user of the sword was given non-detection but was also given body equilibrium, which behaved identically to the devotion from the psionic discipline of psychometabolism.
 * A wielder who was highly knowledgeable found that the cuts from the blade went even deeper. The wielder gained non-detection and body equilibrium. On top of this, the blade was able to ignore enchantments half of the time, even from items.
