Fallen Soldier

After a crucial defeat in a war, your spirit wandered the battlefield in search of a living creature to extract the life out of to insert itself instead. Slowly, you feel like your spirit wants to leave the body to return where it belongs. But it's not entirely the case, it's totally different.

### ETHEREAL FORM

When you reach 3rd level, you are able to shift between etherealness and physical forms. You can forgo an attack to shift into the ethereal form for 1 minute, the attack you forgo cannot be a bonus action. While in ethereal form, you attach yourself to a creature within 30 feet, you move with that creature for the duration and you can't be damaged by attacks or spells. For the duration, the creature has resistance to all damage and whenever that creature is dealt damage, you lose that much hit points. Additionally, the target learns your fighting style and it can use your second wind and action surge features. This creature can't use those features again until it has finished a short or long rest.

Also, you can forgo an attack to hover and attach to another creature within 30 feet granting the bonuses to that creature instead. Once you shifted into ethereal form, you can't do so again until you finish a short or long rest. If the creature you are attached to falls unconcious, you can, at the start of your next turn, forgo an attack to attach to another creature within 30 feet, failing to do so, you return to your physical form. If you fall unconcious while ethereal, you return to your physical form. Whenever you return to your physical form, you do so in an unoccupied space within 5 feet of the targeted creature. You can, at any moment, forgo an attack to return to your physical form.

If you are able to cast spells, you can't cast them while in ethereal form.

In addition, at 9th level, the creature you are attached to can use your indomitable feature. It can't use it again until it has finished a short or long rest.

### GHOSTLY PRESENCE

At 3rd level, your ethereal form can inflict wounds when passing through creatures. When you shift into ethereal form or hovering from a target to another in a straight line, you can force creatures of your choice within 5 feet of the line to make on a Constitution saving throw (8 + your proficiency + your Strength modifier). On a failed save, a target takes 1d6 + your Strength modifier force damage. The damage increases by 1d6 at 10th level (2d6) and 18th level (3d6).

### PHANTOM ORDER

Beginning at 7th level, you are able to move the body of the creature you are attached to temporarily. As a bonus action, you force the creature you are attached to to move up to half its movement speed. This movement doesn't provoke opportunity attacks.

### MIST PROTECTION

At 10th level, you can generate invisible protection while moving around the ethereal plane. Whenever you move on the same space of a creature while in ethereal form, you can give it temporary hit points equal to your fighter level.

### SPECTRAL STRENGTH

At 15th level, you grant your host a few more bonuses. While attached to a creature in ethereal form, you may have that creature's Strength score change to be equal to your Strength score. This feature has no effect on the creature if its Strength is equal to or greater than your Strength.

### SPIRITUAL MARKS

Starting at 18th level, the force damage you deal while changing host can be fatal. Whenever you deal more than 20 force damage to a creature in a single strike, the creature falls unconscious until the start of your next turn.
