Here goes, not exactly the kind of thing you would expect from a gift-giver:
Sjel, The Soul Binder
Lore
They say a soul is something that can be measured. They say it's something that can be seen. And they said every person has a unique soul. But no one has said that a soul can be split and joined, pushed and pulled, stolen or given to someone. And they should have. Because that is exactly what Sjel is doing.
Sjel had a twin brother at birth, but his brother passed away shortly after being born. That moment, everyone could see a green glow emanating from the dead brother to the alive one. Some believe that during this time, the souls of the brothers united in a single body, to live together until their demise. Some, however, believe that Sjel's soul only stole parts of his brother's soul that it could find useful. All everyone knows is that when souls bonded, Sjel now had the ability to shape the souls of nearby living beings in a way he himself finds enjoyable. But the soul of his brother (or parts of it that were in Sjel's body) kept crawing for final resting peace, for liberation from another man's body. The thing Sjel couldn't achieve, even with his great powers, is spliting his soul from his brother's and giving him everlasting peace.
Becoming a teenager, Sjel went to the mountains, training in a forest, completely out of sight from every other human on Valoran. When he returned as a grown man, he was closer to his goal. He had more control, but still hasn't forgotten his goal. He was eager to help those in need, and could bolster a man's abilities by adding a bit of his own soul into them, for a short time. He could fight back when attacked by stealing away parts of his attackers' souls. He became the defender of people and magic, with no one knowing his true goals. Words of his deeds quickly got to summoners in the Institute of War, and Sjel himself learned more of the powerful establishment that League of Legends became, and all of it's members. He joined the League in hopes of finding someone who can help him achieve his goals, and now fights on the Fields of Justice as a champion.

(Casting on self gives you an increase of 50% to regeneration and 40% to healing and doubles your innate's effect).
{Check for combat is done every second. If out of combat, effects won't apply, but the buff won't be removed until the duration times out.}

Soul Burned: 50% of healing and regeneration are transfered to Soul Binder, and true damage is taken every second equal to 500% of Sjel's health regeneration per second. Whenever hit by a Spirit Pulse, you are stunned for 0.3 seconds.
{"Transfer" means that the target loses 50% of their regeneration and healing. Debuff description translates to stunning the spell's target(s). Damages only the primary target.}

CLARIFICATIONS FOR CHALLENGE
Christmas cheer/gift giving: He is a melee support or a fighter, 3 of his spells are used to buff the survivability of your allies, while each makes you lose some of your survivability in return.
Naughty or Nice: None of his abilities are auras, whereas Spirit pulse has an AoE around the target. His ultimate ability heals allies and damages enemies. Removal or application of CC is also dependent of whether target is an ally or an enemy. Spirit pulse also utilises similar mechanism.
That big old sack: Spirit pulse relies on charges, and each charge gives passive bonuses.
