You as the last decedent of this long line of warrior queens, kings, and monarchs are able to use their power to continue fighting. Each ruler had a Diadem which granted them power to aid them in battle, you are able to use every Diadem that has existed in your lineage albeit one at a time. Each Diadem is completely unique and will affect your body and mind differently, but each one was worn by someone who was willing to die for their people, and so are you. You no longer have kingdom of people to protect so your found friends and family are considered your people. You will fight with them and for them, for their safety and prosperity just like your ancestors did for their people and kingdom. Any time you have a Diadem for that day a tattoo above your heart will appear of that Diadem and the other ones for that day.

Bonus Proficiencies

3rd-level Ancestral Diadem feature

You gain proficiency with smith’s tools, and you learn to speak, read, and write Primordial.

Diadem Wielder

3rd-level Ancestral Diadem feature

You can use the magic of the Diadems to enhance your abilities. You learn two Diadems of your choice, from among the Diadems described below, and each time you gain a level in this class, you can replace one Diadem you know with a different one from this feature. When you reach certain levels in this class, you learn additional Diadems, as shown in the Diadems Known table.

Diadems Known

Whenever you finish a long rest, you can decide which Diadems you know that day, you may have only one Diadem that affects you active at a time, however you can have one that affects you and one that affects another person without affecting you active. The passives do not count as "active". (the one exception to this would be the Diadem Of Thorns, you are able to use this one along side one that solely affects you because of the heavy penalties that the Diadem Of Thorns inflicts upon you).

The following Diadems are available to you when you learn a Diadem. If a Diadem has a level requirement, you must be at least that level in this class to learn the Diadem. If a Diadem requires a saving throw, your Diadem Magic save DC equals 8 + your proficiency bonus + your Constitution modifier.

The target can repeat the saving throw at the end of each of its turns, banishing the shackles on a success. Once you invoke this Diadem, you can’t do so again until you finish a short or long rest.

Diadem Of Bone. This Diadems magic evokes the might of your ancestor who wielded it, they knew magic that heavily dealt with death and life. While you have this Diadem selected for the day, you have resistance to necrotic damage and advantage with Charisma (Intimidation) checks.

Unless the save succeeds, the creature is charmed by you for 1 minute. While charmed in this way, the creature has a speed of 0 and is incapacitated, descending into a dreamy stupor. The creature repeats the saving throw at the end of each of its turns, ending the effect on a success. Once you invoke this Diadem, you can’t do so again until you finish a short or long rest.
