Domain Expansion: Eldritch Mausoleum

With an action you expand an Eldritch Mausoleum,  closing all creatures within 50 feet or less of you within a pocket dimension of Zorrion's choosing. Creatures at the edge of your Domain must attempt a Charisma saving throw against your spell save DC + 5. On a failure you get to decide whether to enclose them in the Domain or not, on a success it is up to the creature's discretion. You may exclude creatures from your Domain by having the barrier push against them to the edge as you expand it. The barrier goes around physical objects and expands from you.

When the Domain is cast, Zorrion deems all inside Friend or Foe. Those with "Friend" get advantage on all attack rolls and saving throws against "Foes", and the number needed to roll a crit is reduced by 1 (this effect stacks). Creatures deemed "Foes" will have disadvantage against on all attack rolls and saving throws against "Friends", and the number to roll a crit is increased by 1.

Within the Domain, all your attacks and saving throws have advantage. Attacks and saving throws against you have disadvantage. The number needed to roll a crit is reduced by 2 (this ability stacks),.

The creatures caught within your domain can break out by breaking through the confines of the barrier by attempting a strength check vs your Spell Save DC + 16 or deal 120 damage to a singular location of the barrier. Creatures that wish to attempt to enter the domain can break into the barrier by attempting a strength check vs your Spell Save DC or deal damage equal to three quarters of your hitpoints at a certain point. If the barrier breaks this way then you take 5d6 psychic damage.
