Dimensional Warrior

Gather extradimensional energies to summon portals, allowing for both long ranged attacking and maneuverability

Dimensional tear

Beginning when you choose this archetype at 3rd level, you can open up a small tear in reality in front of you, this allows you to attack any creature you can see within 50ft of you with a one handed weapon or unarmed attack as if you were next to them. When you gain extra attacks each attack can either target the same enemy or spread them out between multiple enemies in range and all tears disappear as soon as you finish the attack action

Spacial shift

Starting at 7th level, you learn to grow your dimensional tears, expanding them enough for you to jump through. As a bonus action on your turn you can Teleport up to 30ft in any direction. You can do this a number of times per long rest equal to your proficiency bonus.

Additionally, when you reach Fighter level 13 the distance you can teleport increases to 60ft

 

Warping counter

At 10th level, you learn to use your abilities to close the gap and surprise attack your foes. As a reaction after being damaged by an attack or spell from an enemy up to 120ft away from you, you can teleport directly behind the enemy and hit the with an attack as you manifest. As long as the creature does not have blindsight or cannot be surprised this attack has advantage. You can do this twice per short rest at Fighter level 10 and 3 times per short rest at Fighter level 20

Dimensional force

Starting at 15th level, your extended exposure to dimensional tears results in your body gaining power when going through dimensions. Whenever you use your dimensional tear or warping counter abilities, your attacks do an extra 1d4 force damage and mark the target with overdimensional energy, preventing them from using any sort of teleportation magic until the start of your next turn

Reality shift

At 18th level, you gain access to an other dimensional space and can trap opponents inside to attack them with your full might. As an action, you can touch one creature and if they fail a Charisma saving throw (DC equal to 8+your constitution modifier +your proficiency bonus) both them and you are transported to a demi plane. It is a 200ft sphere in size and it's Terrain is decided by the player upon gaining this feature. When in this Demi plane all of your features from this subclass have unlimited uses, your dimensional tears can now fit two handed weapons and you gain 20 temporary HP per turn. Both the player and the target exit the Demi plane after 3 turns. On a Successful save the target gains an opportunity attack against you.
