@plum This is the first time a Mimic I placed that was successfully triggered, and this particular group of players didn't vocalize any suspicions on the book being the Mimic. We ended the session with joking that everything is now a potential mimic, especially that rock over there, or perhaps that Stalagmite, maybe even my sword is a mimic now.
I just gotta patiently wait for the Mimic funny business to calm down before I place another one, muhahahahaha.
