Roman War Sorcerer

Prerequisites: Latin

Your innate magic comes from the Roman gods, who's blood is mixed with the blood of your Roman ancestors. Most often, sorceres with this origen trace their descent back to Aeneas or Romulus. The Julian clan is said to descend from Venus, the descendants of Romulus descend from Mars, and the descendants of Aeneas also descend from Venus, though whom you trace your bloodline to is up to you. It does not always have to be blood descend, but could be an ancient pact. Some of these bloodlines are well known, such as the previously mentioned Julian clan, which boasts of members such as Julius Caesar and Augustus. Many more are obscured. Any new sorcerer could be the first of a new bloodline and be a direct demigod or other exceptional circumstance. 

Innate Commander

At 1st level, your innate Roman bloodline grants you innate command skill in the heat of battle. Whenever you cast a spell of 1st level or higher, you can choose 1 ally you can see. They may use their reaction to make one melee or ranged weapon attack against any target within range. 

Roman Heritage

Your Roman ancestry comes from one of the many gods. You may choose one of the gods to be descended from. Your god allows you to cast 1 spell once per short or long rest. Beginning at 2nd level, you may use one sorcery point to cast it again, and use one sorcery point to increase the level it is cast at (One sorcery point per level above 1st) to a maximum level equal to your highest level spell slot.

Arcane Tactician

Beginning at 6th level, if an enemy is flanked by friendly creatures you can see, you gain advantage on spell attack rolls against that creature. 
Additionally, the base level of your innate spell on the table above increases to level 2. If the spell has no benefits from being upcasted, you may instead cast it twice per short or long rest. 

 

Arcane Commander

Your arcane abilities allow you enhanced battlefield control. Starting at 14th level, as a bonus action on your turn, you can move a number of allies equal to your proficiency bonus a number of feet equal to 5xYour Charisma Modifier. This movement takes their reaction, but does not trigger opportunity attacks. You may use this ability a number of times equal to your charisma modifier. 

Voice of the Emperor

Beginning at 18th level, you have become so in tune with your ancestry that the presence of the Emperor himself appears to follow you wherever you go. As an action on your turn, you can channel this presence and become the ultimate battlefield commander. This acts as a concentration spell, and costs 5 sorcery points.  Your presence inspires your allies within 60 ft of you, allowing them to add your charisma modifier to all attack rolls and saving throws. Additionally, enemies who can see you within the 60 ft range must make a wisdom saving throw against your spell save modifier or recieve the effects of the Bane spell for as long as you are concentrating on this ability.
