Lol! I fell down 2 trapdoors solo in normal cata and this dropped off a random white mob... I had to check the event to find out wtf was going on...

+70% More Items From Chests
+32.5% Increased Monster Base Difficulty
+29% to Experience Cap
13.64% Faster Suffusencing
+90% Trapdoor Maximum Monster Level+66.67% Evil Well Longevity
Guess it's working lol. You figure that since the normal trapdoor max monster level is 5, this event makes it go 1-9 monster levels per trapdoor or 1-10?
