Sin Keeper

A halfling takes in the battlefield around her, tallying her wounded allies as sweat drips into her eyes and blood slides off of her blade. She takes a deep breath, and as she lets it go a burst of healing energy washes over her friends, who then grin and rise to begin the fight anew.

Breathing deep to keep calm, the human sweeps her gaze over the enemies surrounding her party. The fight has been long and tough, and one mistake could bring them down. The ghost rushes her ally. As they begin to fall to possession she reaches her fist that direction. With a twist the ghost is successfully expelled as she provides her flagging ally a boost of energy.

The tiefling limps as he makes his way down the stone hallway. His colleagues wait next to the remaining tied down aggressor as he makes his way inside. The tiefling opens his book and hands it off. He lowers himself down to eye level taking his prisoner's measure. Reeking of fear the prisoner quails at the proffered look. The interrogation has begun.

Sin keepers are those who take on or pursue the sins of others and their charges either by conversation or darker means. Whether the energy gathered from these sins is used to heal or harm is a rarely a question with a definitive answer.

Sinful Magic

Sin keepers can be engines of war or walking hospitals, but they can not be one without being the other. A sin keeper comes equipped with abilities to heal, soothe, charm, or harm. Some of these abilities can only be used after harming a hostile creature, and others can only be used after healing.

A sin keeper uses the energy generated from the pain they cause, their own sin, to create wonderful and dangerous effects. These abilities are dichotomous in nature, but are also two sides of the same coin. Regardless of a sin keepers intentions, they will hurt those they must to help those they must.

To Atone or Forget

A sin keeper is quite often burdened by sins witnessed or committed. To alleviate the turmoil from these events, they often are taught to be a beacon for others, a place for people to confess what weighs them down, or a means to ascertain truth at any cost. Sin keepers are those who have made an oath to find and keep sins and secrets or to listen to others who need to speak. Whether that is because they aspire to more, to forget themselves, or to use what they've learned for weal or woe is something that changes for every sin keeper.

While the reasons are plentiful as to why a person would choose this profession, the terrible knowledge and secrets a sin keeper gathers will eventually mount. As they travel along their path towards knowledge that inevitably alters them, a sin keeper must keep a hold of themselves or else lose to the very secrets they amass.

Creating a Sin Keeper

When creating a sin keeper, think about what has put you on this path of sins and secrets. Think about what causes you to want to gather the secrets of others. A sin keeper is often a therapist to those around them, or even an interrogator. Perhaps you committed a crime you need to atone for in your past. Or you just enjoy the stories of others.

However you chose this profession may also dictate what discipline you follow in your duties. Are you here to lend an ear to those around you in an effort to help them mentally? Or do you plan to getting what you need willing or otherwise?

Sin Pool

You must harm your foes to save others, just as you must save others to harm your foes. You have access to a resource called the sin pool. This pool starts at 0.

Whenever you would damage a creature with a CR of 1/4 or higher with a weapon or spell attack roll you gain a number of sin points equal to half the damage. This pools maximum is equal to 10 x your proficiency bonus.

You can spend points from this pool to fuel various class and subclass features.

Additionally, as an action, you may spend a number of points from your pool to create a 1d4 to a 1d10 sin dice and a number of dice up to your proficiency bonus. For example, at 1st level you may spend 8 points to create a 1d8 sin die, or 12 points to create two 1d6 sin dice. As part of that same action, you use the created dice to heal one creature you are touching by the rolled amount.

Keeper's Intuition

During your tenure as a Sin Keeper you have gained a skillful understanding and awareness of anyone you deem your charge. You gain proficiency with Insight and your proficiency bonus is doubled for that skill.

Spellcasting

At 2nd Level, the sins you have garnered lend you the knowledge and aptitude to manipulate the energies they would generate.

Cantrips

You know three cantrips of your choice from the sin keeper spell list. You learn additional sin keeper cantrips of your choice at higher levels, as shown in the Cantrips Known column of the sin keeper table.

Spell Slots

The Sin Keeper table shows how many Spell Slots you have to cast your Spells of 1st level and higher. To cast one of these Spells, you must expend a slot of the spell's level or higher. You regain all expended Spell Slots when you finish a Long Rest.

For example, if you know the 1st-level spell Cure Wounds and have a 1st-level and a 2nd-level spell slot available, you can cast Cure Wounds using either slot.

Spells Known of 1st level and Higher

You know two 1st-level Spells of your choice from the Sin Keeper spell list.

You learn an additional Sin Keeper spell of your choice at each odd numbered level thereafter. Each of these Spells must be of a level for which you have Spell Slots. For instance, when you reach 5th Level in this class, you can learn one new spell of 1st or 2nd Level.

Additionally, when you gain a level in this class, you can choose one of the Sin Keeper Spells you know and replace it with another spell from the Sin Keeper spell list, which also must be of a level for which you have Spell Slots.

Spellcasting Ability

Wisdom is your Spellcasting Ability for your Sin Keeper Spells. Your magic stems from the sins and secrets you gather and your ability to gather them. You use your Wisdom whenever a spell refers to your Spellcasting Ability. In addition, you use your Wisdom modifier when setting the saving throw DC for a Sin Keeper spell you cast and when Making an Attack roll with one.

Spell Save DC = 8 + your proficiency bonus +

your Wisdom modifier

Spell attack modifier = your proficiency bonus +

your Wisdom modifier

Spellcasting Focus

You can use an arcane focus (see the Adventuring Gear section) as a spellcasting focus for your sin keeper spells.

Sin Magic

Beginning at 2nd level, your amassed sins continue to affect your physical and magical combat prowess. Your sin pool gains two effects depending on how much you have accrued.

As long as your sin pool is above half of its maximum, you may add your Wisdom modifier as additional damage to the first damage roll from a weapon or cantrip attack.
As long as your sin pool is below half of its maximum, whenever you would cast a healing spell, you may spend sin points equal to the maximum of each die to reroll a number of die up to your proficiency bonus. You must take the second result.

Disciplines

Upon reaching 3rd level, you begin to specialize in certain sin keeper disciplines. Choose one discipline detailed at the end of the class description. Your choice grants you features at 3rd Level and again at 7th, 15th, and 20th levels.

Discipline Spells

Each type of discipline has a list of spells that you gain at the sin keeper levels noted. Once you gain a discipline spell, you always know it and it does not count against the number of spells you may know.

If you have a discipline spell that doesn't appear on the sin keeper spell list, the spell is nonetheless a sin keeper spell for you.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.
