Hasi's Mansion

The mod centers on a Poltergust that the player wears and uses to suction entities and objects. Upgrades are inserted into the Poltergust with a right-click, and a left-click switches between the upgrades already inserted. When the last upgrade is reached, a left-click or right-click moves back one step at a time.

Keys and elevator buttons carry their own functions: a right-click raises the level and a sneak right-click lowers it, and a level that would fall below 0 is replaced by F. A Super-Suction Socket feature is bound to the default Z key, which locates a nearby socket while the Poltergust is worn, and the socket can pull entities closer in the manner of Luigi's Mansion 3.

Servers that run it need every player to install it too. Files are published for NeoForge only, for 1.21.1. The latest file is 0.2.2, released on 2026-02-10 on the alpha channel. The code is not open source; it is licensed under All rights reserved.
