Arcane Domain

You convert your spellbook into pure arcane energy and entangle it with the very fabric of reality around you, creating a domain where the laws of magic are yours to command.

Upon casting this spell your spellbook disappears and a 100 foot radius spherical barrier appears at a point you choose within range, while within the barrier you gain the following benefits:

• You do not require an arcane focus to cast your spells.
• Spells you cast can originate from any point in the domain.
• When you cast a spell with an area of effect you can choose which creatures within the area are affected.
• You can teleport to any point in the domain as a bonus action on your turn.

Additionally, creatures other than yourself within the domain are subjected to the following effects:

• When a creature casts a spell of 5th level or lower you can choose to have that creature make a concentration check against your spell save DC, wasting the spell on a fail.
• When a creature makes a spell attack or an attack with a magical weapon, you can change the attacks damage to a type of your choice.
• When you use your bonus action to teleport to a point in the domain, you can also choose to teleport another creature in the domain, unwilling creatures will have to succeed a wisdom save against your spell save DC.
• When a creature is forced to make a saving throw against a magical effect, you can choose to give the creature advantage or disadvantage on the roll.

Dispel magic has no effect on the domain, and the domain's effects can only be negated by a space enclosed within the spells Prismatic Wall, Antimagic field, or another Arcane Domain. When another creature casts Arcane Domain within with your own, reality will be returned to normal in the space where the two domains intersect. If this spell is cast on the same point every day for a year, the effects become permanent.
