Regen Hammer

Regen Hammers are rare ghosts in Luigi's Mansion 3. They are a rare variety of Hammers which appear in ScareScraper mode. They have 350 HP, almost double that of a regular Hammer's. They are defeated the same way as normal Hammers. However, if they are released before defeated, they begin to quickly restore or regenerate HP, hence Regen.

Regen Goobs, a rare variety of Goobs, and Regen Slinkers, a rare variety of Slinkers, also appear in the game.
