Designer Notes

Greetings, everyone! I was inspired to make a pair of spiritual subclasses for Dungeons & Dragons 5th Edition due to the lack of existing options available. Here, I have created the Medium roguish archetype for rogues. Quick note, I chose rogue over warlock due to warlock's patron system being tied to a singular being and the existence of the Undying Patron option provided in the Sword Coast Adventurer's Guide. Anyways, let us delve into the Medium.

Mediums may have some quirks to them that made them who they are. Perhaps, they tried to reach out to a recent dead relative without the aid of the church. Alternatively, death may have always been a part of your life, but your ability to speak with them is a more recent development. Whatever it may be, I suggest you, or your player that plans to play this archetype, to select one or more Medium quirks to aid in the roleplay aspect and prevent the character from being just another rogue.

As a Medium, you gain an otherworldly charm, the ability to perform séances, and the ability to shield your own spirit by using others. The Otherworldy Charm is to aid in emphasizing the nature of being a Medium with their ability to speak with spirits but also the people surrounding them that wish to find closure with lost relatives, friends, or ancient mentors. Often, creatures will use their native language, especially in death or private, so I granted Mediums the extra language fluency. Séance is the defining feature for this archetype. Although it grants a 5th-level spell as a ritual, the contact other plane spell is the perfect spell for a séance. I did tune the spell to work in favor for the level the Medium is currently. Finally, Spiritual Shield provides a combat-themed incentive that provides decent sustain at the cost of your reaction.

As a Medium levels, their ties to the spirits strengthens. Spiritual Guidance serves to be a supportive feature, and Vengueful Mark serves as the offensive feature. Both work together to enhance the Medium's stronger connection with the otherworldly. Ethereal Sight capitalizes on ensuring the knowledge on what spirits the Medium calls upon. The sight may also reveal secrets to dungeons that darkvision would not. Furthermore, the additional séances per long rest and more reliable séances provides ribbons to the archetype.

To end this archetype, I thought an Otherworldy Venture would encircle the theme. The Medium's spirit can venture forth, and, perhaps, it can be call upon by other Mediums. Although, the Medium in question should never forget to return to its body.
