Can Gravity Well activate multiple times per cast of a spell

class-featurednd-5espellcastingwizard

Recently I've been looking at ways to make a forced movement character. This initially leads me to look at the warlock, specifically repelling blast. Repelling blast obviously works on each cast of the eldritch blast, as there are other invocations for eldritch blast that only works once per turn.

However, I also noted the Gravity Well feature for the Graviturgy Wizard, which says:

When you reach 6th level, whenever you cast a spell on a creature, you can move the target 5 feet to an unoccupied space of your choice if the target is willing to move, the spell hits it with an attack, or it fails a saving throw against the spell.

This made me think of trying to find synergy with repelling blast and if I could have a 15ft movement eldritch blast, potentially up to 60ft per cast if at a high enough level.

I've looked online but only found people talking about it on Reddit and DnDBeyond and I've found that people who give answers aren't always credible on those sites and people on this site tend to be.

So can the Gravity Well feature trigger multiple times per hit of Eldritch Blast?

Best Answer

Once per Spell

The class feature reads:

You’ve learned how to manipulate gravity around a living being: whenever you cast a spell on a creature, you can move the target 5 feet to an unoccupied space of your choice if the target is willing to move, the spell hits it with an attack, or it fails a saving throw against the spell.

So the trigger is "whenever you cast a spell on a creature" (once) The condition to allow movement is

  • The target is willing to move
  • The spell hits it with an attack
  • Or it fails the saving throw.

So if you cast EB with three attacks and one of them hits, then you move them 5 feet. Or if you cast EB with three attacks and three of them hit, then you move the target 5 feet -- because it is triggered once.

Why is this different from Repelling Blast? Because the trigger is different. Repelling Blast reads:

When you hit a creature with eldritch blast, you can push the creature up to 10 feet away from you in a straight line. Which means each beam would push.

Now, if you wanted to be cheesy and multi classed Wizard/Warlock, you could push them 10ft per blast from Warlock and another 5ft for the spell using Gravity Well for a 35ft (assuming all beams hit).
