I had a titan in my weapon slot, and I changed it to a Pulvy. The enemy has a protected Titanium shield, and my Pulvy does 5 damage. Also, the only thing hitting is momentumed monsters and the weapon.
Before with 71 hp's:
After with 38:
With a bit of elementary math, it should be 71-(7*4)-2, which equals 41. The extra three comes from the pulvy doing 5.
Another note: Flying the Pulverizer removed the momentum effect of both the pulvy and the other pulvy I ended up putting there.
