Domain Expansion

You create a demiplane centered on yourself. The maximum size of said domain is a 500ft cube, though it looks much smaller from the outside. The demiplane looks like however you want, you control the environment and you can choose whether or not to harm any creatures within the demiplane. Upon casting this spell, you can choose five of the following effects.

• Within the domain, all attacks made by you are guaranteed to hit and no saving throws can be made to negate or otherwise avoid the damage.
• Creatures within the domain cannot escape and creatures outside of the domain cannot enter.
• Other than you, no creature can cast any spells.
• For creatures of your choice, the domain counts as difficult terrain.
• Spells cast by you and creatures of your choice cost one less spell slot to cast (for example, a 9th level spell can be cast with a 8th level spell slot.)
• You automatically succeed on Concentration Checks for your spells.
• Your Domain is warded against divination magic. Any attempts to use spells or abilities in that category that are targeted at or inside your Domain automatically fail.
• Your Domain is warded against teleportation. Creatures may not use or benefit from spells, magical effects, or abilities that allow teleportation, planar travel, or ethereal travel.

Inside your domain, you have ultimate control over both the space and what you are capable of within the space. You gain the following effects:

• You can teleport at will to any other location within the Domain. In combat, this ability may be used in place of your movement.
• You can telepathically communicate with any creature in your Domain. This takes no more effort than speaking normally.
• You understand all languages spoken in your Domain, and you are understood by any creature you communicate with.
• You may designate, at will, creatures inside your Domain who are immune to or benefit from the Domain Effects that you choose.

As a bonus action, you can choose to end the spell.
