Plane Stalker

You are becoming one with time and space itself, and are able to hide yourself in the spaces between worlds. You have mastered the art of stealth to the point where you are now able to slip between planes of existence, becoming partially invisible, and gaining the ability to move into spaces you wouldn't normally be able to reach.

Distorting Shroud

You are able to use planar energy to shroud and distort your figure to hide your presence. Gain expertise in stealth if you do not already have it.

Plane Walk

You have gained the ability to slip between the different planes of existence, enabling you to move unseen through space, and even through objects. Starting at 3rd level, you can use your Cunning Action to Plane Walk 10ft. You are able to use this ability a number of times equal to half your level plus your intelligence modifier, recharging every long rest. You can Plane Walk in any direction, even through solid objects. Plane Walk can be stopped by 5ft of solid wood, 3ft of solid stone, or 1ft of solid metal. If you Plane Walk into a solid object take 4d6 force damage, and return to where you originated. Attacks of opportunity cannot be made against you if you attempt to Plane Walk while engaged with an enemy. You are unable to use Plane Walk while restrained, grappled, or any other effect that would make you normally unable to move. Also if you choose to Plane Walk straight upwards, and there is no surface to land on or edge to grab, you will fall and take falling damage as specified in the Players Handbook.

Planar Strike

At 9th Level you begin to understand the nature of the planes you can manipulate. You gain the ability to imbue planar energy into your strikes. Attacks you make with melee weapons are now considered magical for the sake of overcoming resistances. As well, once per short/long rest you can make a Planar Strike: you focus a large amount of planar energy into a strike and deal 3d8 additional force damage with the hit.

Extended Plane Walk

At 13th level, you are able to enter the planes long enough to travel further, as well as bring an ally with you. You gain the ability to cast Dimension door twice per long rest as an innate ability.

Fluid Movements

At 17th level, you become almost one with planar energy, and you gain the ability to weave planar energy into your very movements. You have advantage on all dex saves, ignoring the effects of being grappled or restrained. The number of times you can use Planar Strike per short rest increases to 2. If you use a Planar Strike after using the Plane Walk ability, you can increase the damage to 6d8.
