Domain Expansion

The user conjures a reflection of their souls as another dimension in a 30 ft sphere. Inside the sphere the user has boosted multipliers to all attacks and checks/saving throws made. The user also cannot miss any attacks they make. The spell can be cancelled out by an equal level version of the spell or if another caster casts the spell at a higher level then that version of the spell takes over the area. This dimension is considered a demiplane for all spells and purposes.
