Way of Temptation

Your monastery has a unique way of training their monks. They fashion a container meant to hold powerful entities who constantly tempt the monk to give them more power 

Sin Points

The demon's contained in the glove want out, and will try to gain power by making deals with the wielder

At 3rd level the monk has a pool called sin points, this pool starts at 0 and there is no way to remove points from the pool beyond the DM spending them. These points are accumulated by using certain class features, The DM can use these points for any of the following effects, spending a maximum amount of sin points equal to the player's monk level per turn.

• Spend 1 point to decrease the DC of saving throws caused by the player
• Spend 1 point to increase the DC of saving throws against the player

Spellcasting

Beginning at 3rd level when choosing this tradition, you augment your martial prowess with the ability to cast spells. 

Cantrips

You know one cantrip of you choice from the Warlock spell list. You learn additional warlock cantrips of you choice at higher levels, as shown in the Cantrips Known column of the Way of the Cursed table

Spells Known of 1st Level and Higher

You know one 1st-level warlock spells of your choice, which you must choose from the Evocation and Abjuration spells on the warlock spell list.

The Spells Known column of the Way of the Cursed  Spellcasting table shows when you learn more warlock spells of 1st level or higher. Each of these spells must be an Evocation and Abjuration spell of your choice, and must be of a level for which you have spell slots. For instance, when you reach 9th level in this class, you can learn one new spell of 1st or 2nd level.

The spells you learn at 8th, 14th, and 20th level can come from any school of magic.

Whenever you gain a level in this class, you can replace one of the warlock spells you know with another spell of your choice from the warlock spell list. The new spell must be of a level for which you have spell slots, and it must be an enchantment or illusion spell, unless you're replacing the spell you gained at 3rd, 8th, 14th, or 20th level from any school of magic.

Charisma is your spellcasting ability for your warlock spells, so you use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a warlock spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Charisma modifier

Spell attack modifier = your proficiency bonus + your Charisma modifier
