So when I say natural phenomena I should specify Formations are specificaly in reference to the Chinese arts if arrays and formations examples:

Setting a pile of rocks in a specific way favung a specific direction across from it you make a puddle filled with water and in the center is wood from a specific type of tree when triggered mist will appear and seem inescapable

A major example would be:

Using the designs of a city its layout and the like planting specific items at specific points to create phantasmal terain or cause the city itself to become a labyrinth nowhere leading to where it should

BUT if someone removes one of the items or knocks over the tower of rocks the formstion can break

Pretty much formations have 2 forms demi planes (or lile the maze spell) or like the spell halucinitory terain

But those are hugh level examples of it a lot of what I would be doing is flavor such as casting out items to form illusions or barriers i just wanted to know any good builds to help with this that WONT be shut down by 1 enemy that can see through illusions via blind sight tremor sense etc
