Domain Expansion

This spell can only be used once per long rest. The user needs to concentrate to cast barrier within 50 feet around themselves. Whoever is still within 50 feet of the user when it is finally their turn, will be trapped in the domain. When casting the spell, the user cannot do any actions or bonus actions whatsoever until the next turn.  

After the domain has been cast, then the user no longer needs to maintain concentration. The domain will remain active for 5 rounds after casting. When those 5 turns are over, the domain's effects will no longer be active.

When Domain Expansion is in effect, it will allow the user to ignore the target(s) armor class, dodges, reactions, saving throws or whatever else may prevent them from being hit. This also includes things such as distance or being behind cover. So long as the user's target is within the domain, then they will be able to hit the target with whatever spell or attack they choose. When rolling for damage, every single target within the domain (excluding the user) will take that amount of damage. 

The domain can be broken from the outside by dealing 30 damage to it of any kind. If the user is killed or incapacitated while the domain is active, then the domain will be dispelled.
