Dedication

Many words exist for the heart yet one thing remains constant. The heart is considered the spiritual center by mystics, dreamers, poets, and the like. For most, this concept is merely metaphorical; however, for a select few, the strength of the heart not only exists as a power to be wielded but as something to be protected and nurtured

Unlike other Warlocks who form deals with otherworldly entities or being with great power, a Warden of Hearts is patronized by the bond which they share with another being who they are close to and they have promised to protect in any way possible.

Some scattered records hint that the first of this class may have learned how to utilize the power from the core of the earth and its love for its residents while others speculate they learned how to utilize his power purely through talent and self-discovery. 

Friendly Guide

Take My Strength

Starting at 1st level you gain the ability to gift a friendly creature within 10 feet of you an additional action, however, this costs your action and bonus action. You can only do this with creatures of whom you are emotionally close to and understand.

Let Me Help

Once you reach level 6 you gain the ability to take wounds from a friendly creature by touching them. This restores their wounds for a certain amount of HP, but causes you to take the damage in which you have restored. You can only do this for conscious creatures, and you cannot kill yourself with this ability, meaning the minimum HP this ability can leave you at is 1 HP.

This ability does not work for Necrotic damage or any other damage that cannot be healed by magic for any reason.

Starting at level 6 you can do this for up to 20 HP per long rest.
At level 10 you can do this for up to 40 HP per long rest.

Lets Share

You gain proficiency in Constitution saving throws and can grant that proficiency to one other creature per long rest. Additionally, you gain resistance to necrotic, piercing, and slashing damage from nonmagical weapons.

Spare Them

At level 14 You gain the ability to fully sacrifice yourself as a reaction. If you are within 10 feet of a creature and are not prone, you can choose to put yourself between them and their attacker, using your AC and taking the damage for them.
