Planeswalker

Your innate power comes from the entirety of the planes. The planes call out and awaken those they chose to travel the multiverse. Once awakened a planeswalker has a knack for knowledge about creatures not from the material plane. Some of the greatest planeswalkers use this knowledge to travel the multiverse and establish themselves as rulers. Others seek to help those unable to defend themselves in need of a hero. Sometimes planewalkers establish themselves on a particular plane and align themselves with it, calling it home. Their form, attitude, and spells taking on the form of the plane they spend much of their time on. Or a planeswalker may create a demiplane of their own and sculpt it elements and powers they find most comfortable.

Extra-planar experience

You gain proficiency in arcana and whenever you make an arcana check to decipher information about the planes, planar travel, etc. You add double your proficiency bonus to that roll.

Displacer

Whenever you cast a spell of first level or higher you may teleport up to 30 feet in any direction to an unoccupied space you can see.
You can use this feature only once per turn.

Shimmer

Whenever you are hit by an attack you may use your reaction to expend 2 sorcery point & roll a D20+CHA modifier. If the rolled result is higher than that of the attack you take no damage and teleport 5 feet away from your attack in any direction. This teleportation does not provoke opportunity attacks.

Planeswalk

Beginning at 14th level, you learn the plane shift spell which doesn't count against your number of sorcerer spells known. As an action, you can cast plane shift with this feature, without expending a spell slot, only targeting yourself and without requiring material components. Once you use this feature, you can't use it again until you finish a long rest.

When travelling in this alternate plan, each 1ft of movement in that plane accounts for 3 feet of movement in the material plane an action to return to the plane to travelled from originally. You can use an action to magically appear back into the the plane you originally travelled from.

World sculpter

Beginning at 18th level, the magic of the planes grants you the ability to not just travel through with them but create your own artificial world through an intense effort by imparting a shard of your own planeswalker spark within it.

You learn the demiplane spell which doesn't count against your number of sorcerer spells known, you can cast this spell once per long rest without expending a spell slot. This use of demiplane is special. Instead of a door that requires opening, it is a portal large enough for a large of smaller creature to fall straight through. Rather than opening to an empty room 30 feet in each dimension, it opens to a spherical demiplane 1 mile in each dimension. The edges of this demiplane are foggy and unpassable. While in this demiplane, you can spend an hour creating and shaping it as you like forming forests, mountains, structures and creatures up to CR2, you can create a number of creatures equal to your CHA modifier . Any material created from your demiplane dissipates into smoke if removed from the demiplane. If you create a new demiplane, any creatures (except the ones created by you) inside the extradimensional space are expelled into the open spaces nearest to the entrance.

While in this demiplane, all attacks made against you have disadvantage and you have a flying speed of 60ft.

If you die outside of your demiplane, roll a d20. On a 10 or higher, you discorporate with 0 hit points, instead of dying, and you fall unconscious. Your gear disappears with you and you appear at a spot of your choice 1d4 days later within your demiplane.
