Apparition's Blades

The user of Apparition's Blades  summons two dark, serrated, ethereal blades on one or both arms of the user.  They radiate a purple, sinister aura, and pulsate with power. The use can chose if the spell will only appear on one or both arms. At higher levels, the blades can appear on the legs. At some of the highest levels, this spell can be used to pierce out of any part of the body, and can be used as a type of counter. This spell can be used alongside many actions and attacks, although limiting the user with one bonus attack. This attack strikes fear into the characters unfortunate enough to be hit, bleeding as well. When the time is right, the blades emit a dark shroud of black mist, which expands in a 20ft radius. This conceals the user, and allows the user to attack any enemies caught in the mist. The user can sneak attack and stun the enemies inside, but the enemy will most likely expect to be attacked again, so the user must choose a different target. Until failing to sneak attack an enemy, the user will attack any desired enemy in the mist, and will dissipate once all the enemies have been attacked. If the user fails a sneak attack, the smoke will immediately dissipate. This mist can be used as a hiding spot as well, in which case the mist will last 2 turns. The user is free to rest or heal inside the mist, however, if the user fails a sneak check or the enemy successfully finds the user in the mist, then the mist immediately dissipates. The user is free to cancel the mist at any time.

Damage/Modifiers

Role a d10,(d20 at higher levels), die to determine the damage of the attack or if the action works.

The spell deals necrotic damage when used as an attack.

The spell applies the Frightening  and Bleed status effect.

Can be cast on the legs at higher levels.

Can be used as a counter at some of the highest levels.

When rolling a 20 with the d20 die, the blades emit a dark shroud of mist that conceal the user and characters in a 20ft radius. This allows the user to sneak attack and stun the enemies in the mist for one turn, (assuming the enemy isn't defeated in the sneak attack). The user continuously attacks and deals damage a DIFFERENT enemy in the smoke, until a sneak check fails. The smoke can also be used as a hiding spot so the user can rest and heal, until found. The smoke can remain for 2 turns if used as a hiding spot. The user can only be found if the user's sneak check fails or the enemies successfully find the user.

Downsides

If the spell is used as a bonus attack, then that is the only bonus attack that can be used until dispelled.

When in the shroud of mist, the user cannot sneak attack or stun the same enemy twice.

The shroud of mist dissipates once the sneak check fails once.

The user cannot sneak attack any enemy not in the smoke.

The user must choose if they shall rest and heal or sneak attack enemies while in the smoke.
