[RPG] Does immunity to piercing damage make you immune to the pull effect of the Thorn Whip spell

dnd-5eforced-movementimmunitiesspells

The description of the thorn whip cantrip says:

You create a long, vine-like whip covered in thorns that lashes out at your command toward a creature in range. Make a melee spell attack against the target. If the attack hits, the creature takes 1d6 piercing damage, and if the creature is Large or smaller, you pull the creature up to 10 feet closer to you.

If a character has gained immunity to all piercing damage, would that character also be immune to the pull effect of thorn whip?

Best Answer

Nope.

The pull effect of Thorn Whip is contingent on a successful melee spell attack against a creature who is Large-sized or smaller.

If the attack hits, the creature takes 1d6 piercing damage, and if the creature is Large or smaller, you pull the creature...

If both conditions are true (the attack hits and the creature is no larger than Large-sized), then the pull effect would occur whether or not the creature takes damage.

Note that the spell doesn't explain how or why the creature is pulled. Do the thorns grip them? Does the whip wrap around them? Is it some unseen magical force? Regardless, spells do what they say they do. A hypothetical DM could rule otherwise, but by RAW, the creature is pulled simply because the spell says so.
