Concentration Mage

A pact with your own life essence instead of any otherworldly patron has set these casters on a totally different level of paying with blood, sweat and tears. Honing a deadly knowledge of how magic can exists in blood even if a person doesn't innately have any spell-casting abilities, these casters use that knowledge to gain powerful magics and abilities that otherwise wouldn't exist.

Pain For Profit

You channel the magic and knowledge within you and weave positive benefits from inflicting pain upon yourself.

Whenever you take self damage as a cost of a spell or feature of this class you heal for 1/2 of that damage as Temporary HP at the end of your turn.

Font of Health, With Pain Comes Balance

Your blood starts to ebb and flow with magical warmth. The magic within you gives to you what you try and take away from yourself so that it may continue to hold a place in the world. With the considerable amounts of pain you have to use in order to fruitfully use your magic, you have gained the ability to ignore the effects of pain that is inflicted on you. Additionally it has also unlocked the ability to be able to Concentrate on 2 things at once via magical disassociation.

At the start of your turn in combat you gain THP equal to your level or heal that amount if not at full HP. You can concentrate on 2 different concentration spells instead of only 1. Once per combat you can choose to succeed on a failed Concentration Check.

Broken But Not Forgotten

Through many tests and combats you have figured out that you do not have to lose everything each time your Concentration is broken. Instead with quick thinking and sturdy body you are able to recall what was lost.

You may use your reaction to reapply a Concentration Spell to a target after you fail a Concentration Check. The target needs to make it's saving throws versus your spell DC. You may only use this ability 2 times per long rest.

Unifying Body and Mind & Master of Concentration

Using the many battles and tests you have survived you have figured out a way to fuse your mental aptitude with your tough fortitude through the magical machinations within your Blood magics. Through mastering your body you came to realize that your bond with your blood held many secrets. One thing became very clear in your climb to this mastery, Concentrating on multiple things could be simplified if you just forced spells together as one. It is not an easy process and definitely takes it's toll, but you've done worse to yourself and are able to withstand the toll it takes to do so.

You can now Concentrate on 3 separate Concentration Spells instead of 2. Twice per day you can combine 2 different Concentration Spells to count as 1. Combined Spells fade away and become separate at the end of the day.
