Items with skill:
Easily one of the best passives in the game, as having more Dust makes everything easier - and this provides potentially the largest Dust gains of any skill. On high floors, you may be lucky to find 3-5 Dust in a room (if it even has Dust at all), meaning high level Pilfer can practically double it. This is huge. Even active skills like Dust Drainer can't compare to the value of high level Pilfer. Being able to light more rooms will make your whole run much more comfortable.
Note that the Pilfer hero has to be the first one to open a door for this skill to work - just touching a door as it's opening after another hero activated it will not give the Dust bonus. This also means that having multiple heroes with Pilfer is redundant and will not give any extra bonus over a single hero with the skill. The skill will also only triggers if the room has any Dust.
