Maloney's Mechanism was released in 3.6 along with Synthesis League. Throughout the league, it dropped like any normal unique with ostensibly no ties to the synthesis mechanic whatsoever.

However, this league, it does not drop normally; rather, it only drops from things like Time-Lost Incubators.

This isn't listed anywhere on the poe wiki (including on the Synthesis League page), although it is noted on poedb.

Non-Synthesis uniques were added in 3.6.0 that aren't Synthesis-exclusive (ex. Vixen's Entrapment, Hyrri's Truth).

As far as I can remember, there hasn't been a League unique that was completely disconnected from the League mechanic since Torment. It just seems like an oversight that this one item, completely disconnected from the league's mechanic, is for some reason exclusive to its introduction league.
