Dark Travel

Dark travel makes the caster able to almost instantly travel up to twice their walking speed for the distance.
When using this spell the caster transform themselves into a shadow creature, they are blinded for the duration of the travel.
If the caster passes through another creature while in their shadow form, the creature needs to make a wisdom saving throw of 13, on fail the creature feels uneasy and has disadvantage on their next roll (any roll).
If the spell is used in place with enough light, the creature the caster passes through have advantage on their wisdom saving throw.
When used in the dark, the caster is completely invisible during the travel, anyone targeting the caster looses sight of them(only in the dark), unless the creature has truesight.
