Ok, about powers:

Umbrakinesis - Hypnokinesis-
 * They can surround enemies in pitch-black clouds of dark space.
 * They can use darkness to create portals to travel from one place to the next (Shadow Travel).
 * They can use shadows to cover oneself in darkness to become invisible.
 * They can possibly see through darkness while your enemies cannot.
 * They are able to use black energy to create virtually impenetrable barriers. Hades was even able to block Zeus' Master Bolt.
 * They can control and manipulate the beings that exist there.
 * They can create and dispel shields of areas of total darkness and create and construct weapons.
 * They can heal themselves or others by using darkness (Minor injuries).
 * They can absorb and dissipate shadows.
 * They can become stronger at night or in dark places (e.g. Underworld).
 * They can transform into (living) darkness or shadows.
 * The ability to put people to sleep.
 * Astral projection/dream travel, as in The Lost Hero, Clovis, son of Hypnos, says to have met Michael Jackson in his dreams. In The Blood of Olympus, Nico astral projects himself into Clovis' dream, in order to send a message to Thalia. Hence, demigod children of Hypnos and Hades have much higher control over their dreams than other demigods.
 * May be able to manipulate dreams, since dreams are a part of sleep.
 * Can recover lost memories.

By the way, these are all cannon.
