Mist weaver: beginning at 3rd level 

Mist weaver

Beginning at 3rd level you can summon mists at any time. You gain the ability to cast fog cloud , with the target being self. Once you have used this feature a number of times equal to your intelligence modifier, you must complete a long rest before you can use it again

One with shadows

Starting at 3rd level , you are comfortable when surrounded by fog. When you are surrounded by mists , you gain advantage on Dexterity(Stealth) checks. In addition moving through non magical difficult terrain costs no extra movement if you are under the cover of mist.

Mist sense

Starting at 9th level you have learned the nuances of the mist. Once in the mist you gain mist sense. Mist sense activates once you enter mist, allowing you to use your bonus action to make a DC 15 Perception check, on a successful throw you are able to detect any creature within 20ft of the same mist cloud.

Mist blade

Beginning at 13th level you can create a weapon out of mist. While in mist, you gain access to mist knife , a weapon entirely made out of mist. It has all the properties of a shortsword except that it leaves no visible wounds on the target. Instead the damage it deals is internal and causes the target to bleed for an addition of 1d4 health at the beginning of each of their turns for three rounds.

One with mist

At 17th level you are so familiar with the mists you can melt into them yourself. You can cast the spell gaseous form on your self at will while in the mists
