Ponzi, Pyramid Builder, is a Unique Vault Sentry found in The Vault in Diablo III. He is, apparently, related to Mad Hoff.
In combat, he has Wormhole, Arcane Enchanted and Frozen Pulse affixes.
- This monster's name and title are a likely reference to Charles Ponzi, whose so-called Ponzi Scheme was a basis for financial pyramid fraudulent investment operations. To add to this, Mad Hoff is a likely reference to Bernard Madoff, a man who used this scheme.
