Domain Expansion: Library of Magic

Domain Expansion: Library of Magic creates a pocket dimension that looks like a black sphere from the outside but inside it looks like a lake with a sky full of stars and a moon high in the sky that reflects on the water. People inside the domain can stand on the water like it is solid ground.

Any spells the caster uses automatically hit their target while this domain is active. People inside the domain can move around lIke normal and can attack the caster but they can’t get out of the domain.

This domain cannot be broken from the outside or the inside. If two domains are in the same place a domain clash starts (both casters make an arcane check higher number wins).
