Soulbond: Guardian

You become soulbond permanently with one creature of your choice and you can only grant these benefits:

• Increase your Constitution by 1, to a maximum of 20.

The creature must meet these requirements to become your soulbond partner:

• Must be a 1/2 CR creature or lower, it can also be a player character and it cannot be a familiar.
• Must be your level or lower and have an Intelligence score of 7 or higher, able to share a language, and be able to communicate with you.
• Must have a compatible alignment (it can't be lawful and chaotic, but it can be neutral and lawful/chaotic. It can't be good and evil, but it can be neutral and good/evil).
• Must be a friendly and willing creature.

Only you gain these abilities:

• Telepathy: As an action, you can speak telepathically to your soulbond partner as long as they are within 120 feet of you and your soulbond partner can do the same. You can speak through solid objects with your soulbond partner and know it is beyond the barrier. This ability doesn't have to follow a straight line and can travel freely around corners or through openings.
• Guardian: As a bonus action on your turn, as long as you are 60 feet from your soulbond partner you can reduce your hit points up to 2 times your level and they will gain the exact same amount of hit points but you cannot reduce your hit points under 1. You can use this feature a number of times equal to your Constitution modifier (minimum of once). You regain all expended uses when you finish a long rest.
• You roughly know in which direction your partner is located as long as they are in the same plane.

If your Partner has Soulbound: Overwatch feat, you gain these additional improvements:

• Improved Telepathy: You can now speak telepathically to your soulbond partner as a bonus action rather than an action and your range is increased to one mile.
• Improved Guardian: Now when you use Sacrifice your partner will gain temporary hit points equal to 5 + half of your character's level rounded down (minimum of one).
