Telekinesis: David possesses immeasurably potent telekinesis. With it, he can move extremely heavy objects, such as entire buildings, pin an entire crowd to a ceiling, create nearly impenetrable force-fields, fly, augment his physical strength and speed, disassemble matter and reconstruct it on a molecular level.
Psychic Energy Absorption: David possesses the ability to drain energy from other espers, energy-based attacks aimed at him, and even the environment around him and add it to his own. So far, David only exhibited this ability while at 100% or at ???%. When absorbing energy that originated from other espers, he can also absorb some of their emotions. This is shown when David absorbs attack and feels his sadness. It is even possible for the emotion that he absorbs to overwhelm him to the point that he feels that emotion at 100%, such as when he absorbed enemies attacks and entered Ecstasy 100% due to his influence. His holding capacity is extremely high as well, since he was able to fully absorb all the psychic energy and had released and still survived. However, the process caused him great pain, and he could barely survive. David has exhibited this ability while in "subconsciously" ???% mode.
Psychic Energy Transference: David has the ability to energize others with his power, both espers and non-espers. In the case of the latter, it bleeds out quickly since their bodies can't contain their power for very long, and is of limited use unless the person already knows how to use psychic powers. However, even a non-esper can have basic abilities such as a protective barrier for the duration of this effect. This is first shown when David reaches Gratitude 100% and temporarily relinquishes his powers to his ally. He is also able to transfer his memories and emotions along with the energy, as shown when David relayed his feelings of friendship. Later on, David is shown using this technique without being at 100%
Chlorokinesis: David eventually learns to imbue his psychic energy into plants enabling him to manipulate them and cause them to grow and mature at will.
Spiritual Awareness: David can sense the psychic energy of spirits and other espers. He can widen his "antennae" up to 20 kilometers to sense the presence of other nearby espers.
Astral Projection: David can will his soul/spirit to leave his physical body, appearing as a floating Axolotl-like creature. He can also enter the bodies and minds of others, though whether or not he can completely possess people is currently unknown.

Unlock: Allows the user to open up any lock.
Teleport: Teleport allows David to teleport objects or people to "marked" locations, which are places he has already visited. David can only maintain three markers at a time meaning there are only three places he can teleport to, one of which is the boss room of the deepest dungeon in the World. David can also use a random teleport, removing the need for a marker but in turn transporting a person or an object to a random location in the world.
Explosion: Summon forth a devastatingly large incendiary detonation.
Drain Touch: A skill normally only processed by the undead, David learned this skill from Wiz and can use it to drain mana from others as well as give. It can only be used through direct contact and drains mana very quickly, so David is able to utilize this skill offensively in order to render opponents unable to move once they are drained of mana. Drain Touch isn't very effective against opponents with high endurance, such as Darkness and Mitsurugi, who can usually retaliate before being drained.

Trap Creation: Increases the power and activation chance of any trap.
Create Earth Golem: Summons golems formed from solid, clay, or mud. The size, strength, and operation time of the golem vary on how much mana the user uses.

Deadly Backstab: Kills enemies in one hit if conditions are met. The user being undetected is one of these conditions. The success rate is based on luck.
Lip Reading: As long as David can see someone's mouth he can understand what they are saying. It is often used in combination with his Farsight ability. Eavesdrop: The ability to secretly listen to a conversation from a distance.
Cook: He learned the ability to cook with the idea of having a calm life and even opening a restaurant if he had the chance, he used this ability to help in the Axis Cult festival, making several dishes from Japan to attract customers.
