Would the thorn whip cantrip pluck someone out of a web spell?
Could a gust of wind spell push a creature out of the sticky mass of webbing?
The web spell states:
[...] Each creature that starts its turn in the webs or that enters them during its turn must make a Dexterity saving throw. On a failed save, the creature is restrained as long as it remains in the webs or until it breaks free [...]
Note that the restrained condition does the following things:
- A restrained creature's speed becomes 0, and it can't benefit from any bonus to its speed.
- Attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage.
- The creature has disadvantage on Dexterity saving throws.
No part of the condition prevents a creature from being pushed, shoved, or moved by any sort of thing. This means, grapples, shoves, or spells such as thorn whip, thunderwave, misty step, and gust of wind could all get a creature out of the webs. And since "the creature is restrained as long as it remains in the webs or until it breaks free" the restrained condition would then end.
This is similar to how you can shove your way out of a grapple (by shoving either the grappler or the grappled) as explained in the following questions:
