Planeswalker Spark

A piece of aether - known as a Planeswalker's Spark - has ignited in your soul and you have become a Planeswalker - a mortal with the ability to travel between the planes of the Multiverse. 

You gain the following benefit

• You learn and can cast Plane Shift or Dream of the Blue Veil at will without expending a spell slot and without material components. Once you cast this spell in this way, you can’t cast either spell in this way again until you finish a long rest. You can also cast these spells using spell slots you have of the appropriate level. Your spellcasting ability for this spell is Constitution.
• When you cast Plane Shift or Dream of the Blue Veil on yourself, your belongings on your person are transported too, but not food.
• In addition, when a creature you can see casts Plane Shift or Dream of the Blue Veil, you can use a reaction to also cast the spell (expending a use of this feat or a spell slot as usual) and follow in their immediate wake to appear at the same location.
• In combat if you drop to 0 hit points you can make a Constitution saving throw with a DC equal to the damage taken. On a successful save, you instead takes no damage and Plane Shift or Dream of the Blue Veil away, either shifting to your home plane or one adjacent to it.
• You gain the ability to magically sense the presence of a planar portal. As an action, you can detect the distance and direction to the closest planar portal within 1 mile of you.
• Due to your spark, you gain the effects of Comprehend Languages at all times.

When you first Plane Shift or Dream of the Blue Veil to a plane, you appear in a random location. When you Plane Shift or Dream of the Blue Veil to a plane you've been to before, you appear in the location you were last at on that plane.

-FIXES-

• Need to fix/make new spell for Planeswalk similar to Plane Shift and Dream of the Blue Veil.
• Need to create Ember (Feat Prerequisite) with only Constitution saving Plane Shift/Dream of the Blue Veil as well as replacing it with this feat.
• Later levels allow Plane Shift/Dream of the Blue Veil to include other creatures, items, and magical artifacts.
