Spiritwalker

Your discipline from the Spiritwalkers have taught you how to commune with the spirit realm: 

• Increase you Charisma score by 1, to a maximum of 20.
• You learn the misty step spell. You can cast this spell without expending a spell slot. 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 this spell using spell slots you have of the appropriate level.
• You may expend one hit die and add that value when making death saves or on medicine checks to stabilize a dying party member.
