Oath of the Martyr

Oath of the Martyr Paladins believe in sacrificing themselves before letting harm come to others.  They focus on giving of themselves to protect others.

Gift of Vitality

You are able to use up your short rest healing hit dice to increase the potency of your Lay on Hands or your Divine Smite.  You must declare this before you do either action, and at which point you roll your Lay on Hands or Divine Smite as usual, and then additionally roll one of your hit dice (including the constitution modifier) and add it to the total.  

Oath Spells

You gain oath spells at the paladin levels listed.

Demanding Presence

As a reaction, whenever you make an attack of opportunity you have the option to make an opposed charisma check.  If you succeed, the target loses their movement for the turn and is unable to attack any target other than you in the current round.

A Life for a Life

Ressurecting you no longer requires most physical components to perform, instead it only requires a single tear shed genuinely for your death.

Furthermore you now have the ability to exchange your life for that of another.
Once per long rest, as an action, you may touch a deceased being who has died no more than 1 hour ago. You must then make a constitution saving throw vs the level of the target. If you are successful they are ressurected, with your remaining hitpoints split equally between yourself and the deceased. If half of your HP is greater than their maximum HP, then you only lose enough to bring them to full.

If you fail the saving throw, you instantly die, but the target is still ressurected and all remaining HP you had are transferred to them.

Gift of Suffering

At 20th level, as an action you can enter a state for one minute where with any damage you take, you can heal the same amount to your allies within 60ft. The amount is a total and can be split between any number of targets less than the damage you have taken, but may not include yourself.

Equally, if during this time you suffer some negative status effect, you may remove a similar status effect from one of your allies.

Once you use this feature, you can't use it again until you finish a long rest.
