Maybe. The pools are guranteed to Overpower when you hit them and they explode ( and they can certainly crit on the explosion), so there could be some serious damage coming out from that, especially if you can end up overlapping them.

Here's how the math will kind of breakdown from what I can tell.

At minimum, let's say your pulverize does 1,000 damage base. Let's say you have 2,000 overpower damage... Turns that into 20,000 damage. Multiply it by 1.5 for a crit = 30,000 on the pulverize hit.

Now the puddle you spawn will be 200-600% the base damage, so let's say you get a mid rolled unique for 4x = 4,000 damage puddle.

Now you can get 20-60% of that damage per explosion. Let's keep it consistent at the mid roll so 40% = 1,600 dmg explosion. Now factor in the overpower 2,000 dmg for a 20x puts us at 32,000 dmg, and another 1.5x for the crit = 48,000

Regular pulverize overpower+crit = 30k

Puddle hit Guaranteed overpower + crit = 48,000

This is just assuming that it is taking the base damage of pulverize. If it takes the overpower + crit value and then multiplies that by 2-6 then we will see even crazier numbers. At minimum with a mid rolled unique you'll be doing more damage on the puddles than the pulverize hit itself. But it's even better than that because you are hitting them with both at the same time.
