Now, that's how you stop some npcs from pursuing the party in some dungeon, just fill the dam corridor with rope, they will never pass that, not even a fireball will destroy it all in a hit since it will burn and keep burning for at least 2 turns

in my way, my character is kinda rolled as a half djinn from Woderland, so i just play it as if he create stuff from nothing for his spells but the feature i play it as if he just "happens to find stuff around", and it goes to hilarious situations like being in nowhere and then somepne says something like "we need X to do this" and my bard just says "why dont we use this one that is right here?" and then suddenly there is the object, which considering that a t lv14 you can make a damn Trebuchet (huge size) is hilarious 😂🤣

Add "Dropped a 15x15x15 block of stone on some drow levitating up a tower wall, from the tower's top.  It wasn't pretty for them.
