A piece of aether has ignited in your soul and you have become a planeswalker, granting you the following benefits:
- You learn the plane shift spell and can cast it without expending a spell slot and without material components, targeting only yourself. Once you cast this spell in this way, you can’t cast it in this way again until you finish a long rest. You can also cast the spell using spell slots you have of the appropriate level. Your spellcasting ability for this spell is Constitution.
- In addition, when a creature you can see casts plane shift, 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.
