What is Essence Trap Network?

What does it do? Efficiency means the ratio between benefit and cost improves. The UI shows no change. What does this passive do? Cost doesn't seem to change. The UI does not say if the essence bonus increases with each trap built. Is it bugged? Dead passive?

Havent played in over a year, but several of the traps either had bugs or had effects that didnt register in the UI.

That one works. It's based on a percentage of what the killed monster normally awards for Essence drops, so the gain is fairly small when you have low levels of the passive purchased and/or you have few Essence Traps on the map. You also have to take into consideration that the monster has to be killed on an Essence Trap for it to trigger,and that weaker monsters that do not provide much Essence reward will not provide much (if any) bonus from an Essence Trap at all.

At higher levels of the Passive though, it can add significantly to the Essence generation when killing the larger monsters on fully upgraded Essence Traps. I haven't done the individual math, but on a level 20 Passive, 3-star Essence Trap, augmented with either the Merc's or the Sorceress's Essence gatherer abilities, I've seen Lesovik Shamblers or White Wobblers award as much as 3,000 Essence by themselves when 4-6 Essence traps have been unlocked across the map.
