Domain expansion

Creates a 100ft cube around the caster, that is the casters domain, giving them an absolute advantage in that environment. As long as this is up you always have advantage, this spell is also determined by what item is used to cast it, and which spell slot it is put in.

1st - 3rd slot - permanent advantage, as well as a changed environment allowing for everyone who has lived in that environment to always be able to hide as a bonus action, no matter what.

3rd - 5th slot - Only gives the buffs to the caster and the casters allies not allowing enemies that also recognize the terrain to hide, or use it to there advantage.

5th - 7th slot - This allows the domain to be expanded much much larger than its normal size, it can also be left behind by the caster, but it wont give any advantages to anyone inside, its just a large scale change of environment. If its kept to its normal original size the domain can be manipulated to become difficult terrain for all non-friendly targets giving them all disadvantage and a -1 on all save or dodge rolls.

7th - 8th slot The domain completely works for the caster, hitting every enemy caught in the area every single turn with 1d10 bludgeoning damage , with the only way to avoid it being leaving the domain or flight. If flying they must take a perception check, if they fail it they are hit twice instead of once, if they succeed it they completely avoid damage.

9th slot - Depth of personal psyche, makes a domain based completely on the caster and of the caster choosing. Allowing them to roll a d20, and roll above 15 allow them to completely dodge all ranged attacks that come there way, and a roll of a nat20 allows them to be immune to damage. As well as allowing the caster to chose the damage type and it being a 2d10 damage every turn instead
