Never caught unarmed, the soulknife is about using the power of the soul as a weapon. Creating a soul blade is the core of the soulknife, and with it, they are deadly combatant combined with their ability to cast, makes foes think twice about this opponent 

Mind Blade

You gain proficiency in Simple weapons and short swords. As a bonus action, you can create a semisolid blade composed of psychic energy distilled from your mind. The blade is identical in all ways (except visually) to a shortsword. The Mind Blade glows phosphorescently in the color of your soul, and sheds dim light in a 5 feet radius. You use your Intelligence modifier for attack and damage rolls made with this weapon. The blade lasts until you dispel it as a bonus action or it is forcefully removed from your grip/possession. You may throw your Mind Blade as a ranged weapon with a range of 30/60 feet. Whether or not the attack hits, the mind blade then dissipates.

Your Mind Blade counts as magical for purposes of overcoming resistance and immunity and you can have up to two blade and wield both if you so choose.

You can now use your soul to protect you from harm by shaping it into a suit of armor. While wearing this armor, you are considered proficient in it and your AC is equal to 10 + Intelligence Modifier + Dexterity Modifier. While in soul armor you can still gain the benefit of the Defense fighting style should you have it. Additionally, you can shape your Mind Blade into a shield, this count towards the summoned weapons.

Extra Attack

Your Soul Weapon can only manifest as the weapon it was originally and you gain proficiency with it if you don't already. You can only have one magic weapon fused at a time and if you were to attempt to fuse another, the previous becomes defused. This soul weapon does not count towards the number of summoned weapons.

Mind Barrier

Starting at 10th level, you gain resistance to psychic damage and advantage in saving throws against fear, charm, mind control effects and any affect that would attempt to alter your mind.

Phantom Knife

Starting at 14th level, you can make an attack that phases through most defenses. As an action, you can make one attack with your Mind Blade. Treat the target’s AC as 10 + Dexterity modifier against this attack, regardless of the target’s actual AC. You can only use this feature a number of times equal to 1 + your Intelligence modifier before taking a long rest.
