The Brotherhood of the Scarlet Sign, otherwise known as the Scarlet Brotherhood, is an evil organization led by a cadre of warrior monks trained in the deadly fighting arts. The mission of the Scarlet Sign is world conquest under the rule of the ancient Suel people, and nothing less than the re-establishment of the Suloise Imperium. Non-humans and humans of other than Suel heritage are to be subjugated, in order to finally bring about peace on a worldwide scale, under the leadership of the Chosen People. All those who follow the Way of the Scarlet Sign must be humans of lawful evil alignment.

Shield of Ki

Starting when you choose this tradition at 3rd level, if the monk is attacked by an effect that requires a saving throw, the monk takes no damage if the saving throw is successful, even if he or she would normally take half damage or suffer some other effect. This takes a bonus action to use.

Body Mastery

At 6th level, you may regain three hit points per experience level. This counts as an action, and may be done if the character is at zero hit points, unconscious, or both. You must take a long rest before doing this again.

Touch of Death

Beginning at 11th level, your mastery of influencing and interrupting others’ ki is such that you can strike them dead with a single blow. When you hit an opponent with an unarmed strike, you may spend 3 points of ki to attempt the quivering palm. 

 

At 11th level, your mastery of influencing and interrupting others’ ki is such that you can strike them dead with a single blow., you can spend 3 ki points to start this horrible technique, which last for a number of days equal to your monk level. The attack on the enemies psyche is harmless unless you use your action to end it. To do so, you and the target must be on the same plane of existence. When you use this action, the creature must make a Constitution saving throw. If it fails, it is reduced to 0 hit points. If it succeeds, it takes 5d10 necrotic damage.

You can have only one creature under the effect of this feature at a time and only use it once per long rest. You can choose to end the attack harmlessly without using an action.

Astral Projection

At 17th level, the monk can separate his ki from his body, replicating the effects of an Astral Projection spell with the following differences;
1) the effect takes only a single turn to take effect,
2) it may be done once per week,
3) there is no time limit on how long the monk may be in astral form, but his or her physical body will still require nourishment.
