Also, there is a spell called Rope trick. Quote "You touch a length of rope that is up to 60 feet long. One end of the rope then rises into the air until the whole rope hangs perpendicular to the ground. At the upper end of the rope, an Invisible entrance opens to an extradimensional space that lasts until the spell ends.
The extradimensional space can be reached by climbing to the top of the rope. The space can hold as many as eight Medium or smaller Creatures. The rope can be pulled into the space, making the rope disappear from view outside the space.
Attacks and Spells can't cross through the entrance into or out of the extradimensional space, but those inside can see out of it as if through a 3-foot-by-5-foot window centered on the rope.
Anything inside the extradimensional space drops out when the spell ends."
Larian doesn't implement it yet, but when they, it will be fun
That is one of those spells that I'd be very surprised if they get implemented since they either has no effect on the game play/world or too much effect. So I wouldn't keep my hopes up for a "when".
Edit: ^ IE spells that doesn't help with combat, exploration, dialogue or other in game mechanics. Example: Why implement Alarm spell if there will be no random encounters when resting etc.
Or spells that would be too much trouble making in a visual media. Example: Spells that effect static surroundings like walls etc.
Or spells that will pass both exceptions above but are deemed to be too niche.
